PM2.5 Forecast for Beijing – Saturday, February 1, 2014

Saturday looks like another day for poor air quality in Beijing.  We should see high AQI numbers overnight, but the pollution should decrease somewhat in the early morning hours.  Although it is unlikely, we cannot rule out the possibility that we could drop as low as Unhealthy for Sensitive Groups in the morning.  More likely, we will drop into Unhealthy for a period of time, then we will see increasing pollution from just after noon through the remainder of the day. 

EXTENDED FORECAST

SUNDAY, February 2:  Sunday should bring us good air quality again.  The current forecast gives us weather conditions that should leave us with clear skies sometime between 9AM and 2PM.

MONDAY, February 3:  The good air quality should continue for nearly the entire day on Monday.  We could see rising PM2.5 levels late in the day, but likely not until after sunset.

TUESDAY, February 4: The run of good air could last for a few hours on Tuesday, but we should see deteriorating air quality after noon at the latest.

PM2.5 Forecast for Beijing – Friday, January 31, 2014

We're expecting better than average air quality for Friday.  After higher PM2.5 levels overnight, it looks likely that the pollution should clear at least somewhat in the early morning hours.  There is some variation in the weather forecasts, so the possible range we're predicting for tomorrow's low point is fairly wide.  After the morning's clearing skies, we expect increasing PM2.5 levels in the afternoon.  On any other day, the evening's air quality should be fairly stable, but the presence of fireworks could significantly increase the evening's readings. 

EXTENDED FORECAST

SATURDAY, February 1: The first day of February may be a mixed day for air quality.  We could see decent air quality in the morning, but we could also see Very Unhealthy or higher pollution levels at points in the afternoon and evening.

SUNDAY, February 2:  Sunday should bring us good air quality again.  The current forecast gives us weather conditions that should leave us with clear skies sometime between 9AM and 2PM.

MONDAY, February 3:  The good air quality should continue for nearly the entire day on Monday.  We will likely see rising PM2.5 levels late in the day, but likely not until after sunset.

PM2.5 Forecast for Beijing – Thursday, January 30, 2014

Thursday's forecast is looking better now than it was.  It looks almost certain that we will have Good/Moderate air quality by the time we wake up in the morning, and PM2.5 levels should remain low at least through about noon.  But after lunch, PM2.5 levels should start moving and continue moving up throughout the rest of the day. 

EXTENDED FORECAST

FRIDAY, January 31:  Friday looks like something of a transition day.  While not giving us fully clear skies, the weather conditions should keep the pollution from accumulating too much.  It is most likely that we will see conditions at Unhealthy for Sensitive Groups or Unhealthy throughout the day.  Given the widespread shutdown of industry during the holiday, Friday is likely to be a better than average day.

SATURDAY, February 1: The first day of February is shaping up to be a disappointment when it comes to air quality.  Look for Very Unhealthy or higher pollution levels at points through the afternoon and evening.

SUNDAY, February 2:  Sunday should present us with a chance at good air quality again.  The current forecast gives us weather conditions that could leave us with clear skies after noon.

PM2.5 Forecast for Beijing – Wednesday, January 29, 2014

If you think that the graph for Wednesday's predicted air quality looks strange, you're correct.  This graph tells the story of two distinctly different outcomes for Wednesday (one on the high side and one on the low side), and there is a weather forecast that supports either extreme.  Under the first forecast, we should see improving air quality through the morning, then worsening conditions in the afternoon.  But under the second forecast, we would see increasing PM2.5 levels for basically the entire day, until after about 8PM.  We think there is about a 50/50 chance for each of these scenarios, so we will be hoping for the best for Wednesday's AQIs. 

EXTENDED FORECAST

THURSDAY, January 30:  Thursday should be a day with varied air quality.  There is a strong chance of good air quality in the early morning, but it looks like conditions should be deteriorating again by late afternoon.  This will likely be exacerbated late in the evening by smoke from the New Year fireworks.

FRIDAY, January 31:  Friday is now looking like another mixed day.  We could see improved air quality in the early morning, but after about 9AM things should deteriorate.  There is a chance that we will see AQI levels at Very Unhealthy or higher at some point, although we could see fairly mild increases, given the widespread shutdown of industry during the holiday.

SATURDAY, February 1: The first day of February is shaping up to be a disappointment when it comes to air quality.  Look for Very Unhealthy or higher pollution levels at points through the afternoon and evening.

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Tuesday, January 28, 2014

After clearing skies on Monday evening, we're expecting better than average air quality for Tuesday.  The general trend for the day will be increasing pollution, but it is difficult to tell when we'll climb up into the Unhealthy range.  We think it is most likely that we will make it to Unhealthy fairly early in the morning, with the AQI tracking near the top of our predicted range, but there is also the chance that the good air will last until after noon.  We'll hope for the best, but keep an eye on the hourly reports throughout the day. 

EXTENDED FORECAST

WEDNESDAY, January 29: We’re expecting poor air quality on Wednesday morning and afternoon, with Unhealthy or higher levels, then we should see the pollution decrease in the evening.

THURSDAY, January 30:  Thursday should be a day with varied air quality.  There is a decent chance of good air quality in the early morning, but it looks like conditions should be deteriorating again by the afternoon and through the evening.  This will likely be exacerbated late in the evening by smoke from the New Year fireworks. 

FRIDAY, January 31:  The poor air quality from Thursday evening should continue into Friday, and there is a good chance that we will see AQI levels at Very Unhealthy or higher at some point. 

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Monday, January 27, 2014

We were very fortunate to have the good air quality stay around for most of Sunday, but Sunday night and Monday are a different story.  We've already seen increasing PM2.5 levels, and that should continue through early Monday morning.  We should peak at Very Unhealthy or Hazardous sometime after sunrise before the pollution starts to drop off again between late morning and afternoon.  The weather forecasts for the afternoon diverge significantly, and they predict two different outcomes.  The first forecast would have us drop down to Good or Moderate levels as early as mid-afternoon and continuing at that level for the rest of the day.  But the second forecast would give us a much slower reduction that would likely leave us no better than Unhealthy at the lowest point of the day.  So for Monday afternoon, it's a good idea to keep an eye on the hourly AQI reports to see where things are headed. 

EXTENDED FORECAST

TUESDAY, January 28:  Tuesday is looking like another day with mixed air quality.  We could see fairly low AQIs in the early morning and in the afternoon, and although the pollution should accumulate some, it looks like the AQI is likely to stay at Unhealthy or lower for the entire day.

WEDNESDAY, January 29: We’re expecting poor air quality on Wednesday, almost certainly at Unhealthy or higher levels all day.

THURSDAY, January 30:  Thursday should be another day with varied air quality.  There is a decent chance of good air quality in the early morning, but it looks like conditions should be deteriorating again by the afternoon and through the evening.

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Sunday, January 26, 2014

Sunday may be a mixed bag for air quality.  We're expecting increasing PM2.5 levels overnight through about sunrise, and we should be at Unhealthy or Very Unhealthy at the peak.  Then through the morning, the PM2.5 should stabilize or decrease somewhat.  Sunday's weather pattern is unusual for Beijing, so it is difficult to say whether the predicted weather will result in a big drop in the pollution or just a small drop/leveling off.  In any case, we expect the pollution to accumulate again in the evening.

EXTENDED FORECAST

MONDAY, January 27:  Monday still looks like it will give us a chance at good air quality, with that clear air most likely arriving in the late afternoon or evening after we spend the rest of the day with poor air quality.

TUESDAY, January 28:  Tuesday is looking like another day with mixed air quality.  We could see fairly low AQIs in the early morning and in the afternoon, and it looks like the AQI is likely to stay at Unhealthy or lower for the entire day. 

WEDNESDAY, January 29: We're expecting poor air quality on Wednesday, almost certainly at Unhealthy or higher levels all day. 

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Saturday, January 25, 2014

For Saturday, we're still holding out hope that Friday evening's good air quality will stick around for a bit.  We could see the PM2.5 increase somewhat overnight, but the PM2.5 should be decreasing in the morning.  We should see our lowest pollution levels around early afternoon, then in the late afternoon and evening we should see the air quality deteriorate fairly quickly. 

EXTENDED FORECAST

SUNDAY, January 26:   For Sunday, we're expecting poor air quality.  We could see a dip in the pollution between late morning and early afternoon, but we should have Unhealthy or higher PM2.5 levels for the entire day.

MONDAY, January 27:  Monday should bring us another chance at good air quality, most likely arriving around noon or early afternoon after a morning with poor air quality. 

TUESDAY, January 28:  On Tuesday, we should be back to poor air quality, with the AQI at Unhealthy or worse for the entire day. 

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Friday, January 24, 2014

After Thursday's poor air quality, we have a good chance at greatly improved air quality on Friday.  We're expecting PM2.5 levels to start dropping in the early morning hours, and we could see Good/Moderate air quality as early as 7 or 8AM.  There is some chance that we will not see the pollution clear entirely, but in any case we should see Friday's AQI at lower levels than Thursday's. 

EXTENDED FORECAST

SATURDAY, January 25:  It looks like the good air quality could continue through the morning and possibly into the early afternoon, but we expect deteriorating conditions in the afternoon and evening.

SUNDAY, January 26:   The extended forecast predicts weather conditions that are likely to give us high AQI levels.  We could see a dip in the pollution between late morning and early afternoon, but we should have Unhealthy or higher PM2.5 levels for the entire day with a good chance at seeing Very Unhealthy or worse conditions.

MONDAY, January 27:  Monday should bring us another chance at good air quality, most likely in the afternoon or evening. 

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Thursday, January 23, 2014

On Thursday, we're in for poor air quality all day.  We could see some variability in PM2.5 levels (as shown in the graph), but we're expecting to be at Very Unhealthy or higher AQI for the entire day.

EXTENDED FORECAST

FRIDAY, January 24:  There is a very good chance of clearing skies on Friday, likely early in the morning.  That should give us AQI readings at Good or Moderate for the entire day.

SATURDAY, January 25:  It looks like the good air quality will continue through the morning and possibly into the early afternoon, but we expect deteriorating conditions in the afternoon and evening.

SUNDAY, January 26:   The extended forecast predicts weather conditions that are likely to give us high AQI levels.  We could see a dip in the pollution between late morning and early afternoon, but we should have Unhealthy or higher PM2.5 levels for the entire day. 

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Wednesday, January 22, 2014

Wednesday brings us back to poor air quality in Beijing.  Overnight, we expect increasing PM2.5 levels, but there is a good chance that things will level out or drop a bit during the morning.  But after noon, we expect the buildup to start again, likely taking us into the Very Unhealthy range before midnight. 

EXTENDED FORECAST

THURSDAY, January 23:  Thursday will likely be similar to Wednesday with slightly improved air quality in the morning and deteriorating conditions in the afternoon.  The poor air quality should continue with high AQI levels all day, likely at Very Unhealthy or worse in the late afternoon and evening.

FRIDAY, January 24:  There is a good chance of clearing skies on Friday morning with AQI readings at Good or Moderate; but there is also a chance that the weather will only reduce the AQI slightly, leaving us at Unhealthy or higher.  But even if we see that clearing occur, we should see increasing pollution in the evening.

SATURDAY, January 25:  We expect rapidly deteriorating conditions in the early morning hours, then stable or slightly deteriorating conditions in the afternoon.  Overall, it's likely we'll spend the day at Very Unhealthy or higher AQI levels.

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Tuesday, January 21, 2014

After a great day on Monday, we should have a few more hours left of good air on Tuesday, but that can't last all day.  Sometime between late morning and mid-afternoon, we can expect the PM2.5 to start accumulating.  Depending on how the weather behaves, we could stay as low as Unhealthy, or the AQI could climb up to Very Unhealthy before midnight. 

EXTENDED FORECAST

WEDNESDAY, January 22:  Poor air quality should be the order of the day.  We might see lower pollution levels in the morning, but we should have Unhealthy or Very Unhealthy PM2.5 levels for much of the day.

THURSDAY, January 23:  Wednesday’s poor air quality should continue on Thursday; expect high AQI levels all day, likely at Very Unhealthy or worse.

FRIDAY, January 24:  There is a good chance of clear skies on Friday morning, but there is also a chance that the weather will only reduce the AQI slightly.  But even if we see some clearing in the morning, we should see increasing pollution in the evening. 

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Monday, January 20, 2014

It took a little longer than expected, but our good air quality finally appeared on Sunday evening.  For Monday, we can expect that good air quality to continue for almost the entire day.  We might see a slight increase in pollution in the evening, but that looks like a small chance at this point.

EXTENDED FORECAST

TUESDAY, January 21:  There is a decent chance that Monday’s good air quality will carry over for part of Tuesday, but we can expect the PM2.5 to start accumulating again sometime between mid-morning and late afternoon.

WEDNESDAY, January 22:  Poor air quality should be the order of the day.  From the extended forecast, it looks like we will have Very Unhealthy PM2.5 levels for much of the day.

THURSDAY, January 23:  Wednesday's poor air quality should continue on Thursday; expect high AQI levels all day.

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Sunday, January 19, 2014

We were able to enjoy just a few hours of good air on Saturday before conditions worsened.  Sunday presents the opposite scenario:  we will need to wait out some poor air quality in the morning before conditions improve in the late morning or early afternoon.  Look for Good/Moderate air to arrive sometime between 10AM and 5PM, most likely around noon or 1PM. 

EXTENDED FORECAST

MONDAY, January 20:  We're expecting Good/Moderate air quality for Beijing all day on Monday.

TUESDAY, January 21:  Monday’s good air quality should carry over for part of Tuesday, but we can expect the PM2.5 to start accumulating again in the afternoon and evening.

WEDNESDAY, January 22:  Poor air quality should be the order of the day.  From the extended forecast, it looks like we will be looking at Very Unhealthy PM2.5 levels for much of the day. 

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Saturday, January 18, 2014

We were able to enjoy some Good air quality on Friday, but only for the briefest of moments before the pollution piled on again.  On Saturday, we should get another chance at some good air quality.  Look for the PM2.5 levels to start dropping at or shortly after midnight.  Our possible window for Good/Moderate air quality is between about 6AM and 6PM with high levels of pollution at either end of the day. 

EXTENDED FORECAST

SUNDAY, January 19:  We should start off the morning with poor air quality, then there is a good chance we will see the skies clear again, likely after noon.  After that, the pollution levels should remain low for the rest of the day.

MONDAY, January 20:  If the extended forecast holds, we can expect Good/Moderate air quality for Beijing all day on Monday.

TUESDAY, January 21:  Monday's good air quality should carry over for part of Tuesday, but we can expect the PM2.5 to start accumulating again in the afternoon and evening.

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Friday, January 17, 2014

The weather that would have cleared Beijing's air on Thursday afternoon never actually arrived, so the poor air quality will be hanging around for a while longer.  We can expect very high AQI levels through Friday mid-morning, but between mid-morning and mid-afternoon we should see the pollution start to clear out.  If all goes well, we could see Moderate air quality by late afternoon, or we might have to wait until later in the evening for some decent air quality.

EXTENDED FORECAST

SATURDAY, January 18:  Saturday looks like a fairly average day for Beijing.  We should see somewhat clear skies in the morning (a carry-over from Friday’s clearing), then increasing pollution in the afternoon and evening.  Unless the forecast changes, it looks unlikely that the accumulation in the evening would happen quickly, so we should top out at Unhealthy or Very Unhealthy. 

SUNDAY, January 19:  There is a good chance we will see the skies clear again on Sunday, likely between about 8AM and noon, then the pollution levels should remain low for the rest of the day. 

MONDAY, January 20:  If the extended forecast holds, we can expect Good/Moderate air quality for Beijing all day on Monday. 

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Thursday, January 16, 2014

Wednesday evening was a startling reminder of how quickly the PM2.5 pollution can accumulate in Beijing.  For Thursday, we will see those Beyond Index levels continue briefly before the pollution starts to drop off a little before sunrise.  The PM2.5 should continue to drop until about noon, when we should reach the low point of the day and when the pollution starts to accumulate again.

EXTENDED FORECAST

FRIDAY, January 17:  High PM2.5 levels on Friday morning should give way to clearing skies sometime in the afternoon.

SATURDAY, January 18:  Right now Saturday looks like a fairly average day for Beijing.  We might see somewhat clear skies in the morning (a carry-over from Friday's clearing), then increasing pollution in the afternoon and evening.

SUNDAY, January 19:  Look for poor air quality again on Sunday, but there is a chance that the pollution levels will drop off some in the evening. 

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Wednesday, January 15, 2014

Wednesday's air quality will be mixed as we see lower AQI levels in the morning and much higher numbers in the afternoon.  We should see the pollution decrease to Unhealthy or Unhealthy for Sensitive Groups in the early morning, but by noon or earlier the pollution should be increasing again.  Look for us to move back into Very Unhealthy or Hazardous by evening.

EXTENDED FORECAST

THURSDAY, January 16:  Thursday looks very similar to Wednesday, with lower pollution levels in the morning and higher levels in the evening. 

FRIDAY, January 17:  High PM2.5 levels on Friday morning should give way to clearing skies sometime in the afternoon. 

SATURDAY, January 18:  Right now Saturday looks like a fairly average day for Beijing.  We might see somewhat clear skies in the morning, then increasing pollution in the afternoon and evening. 

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Tuesday, January 14, 2014

Tuesday looks like another day for poor air quality in Beijing.  We should see some reduction in pollution in the early morning hours, but it is unlikely that it will drop below Very Unhealthy or Unhealthy.  Then, after noon, we should see the PM2.5 levels increasing again through the rest of the day.

EXTENDED FORECAST

WEDNESDAY, January 15:  It continues to look like we could see some high pollution levels on Wednesday.  Air quality should be somewhat better in the morning, but it is likely that we will see Hazardous AQI levels in the afternoon or evening.

THURSDAY, January 16:  High pollution levels should continue today; it looks unlikely that we will see air quality better than Very Unhealthy. 

FRIDAY, January 17:  We should get a break from the high pollution levels at some point on Friday.  Big air movements should greatly improve air quality somewhere between late morning and late afternoon.

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Monday, January 13, 2014

Monday is likely to fall short of Sunday's good air quality.  We should be at Unhealthy conditions overnight, then we should see the levels of PM2.5 drop somewhat after sunrise.  Shortly after noon, the pollution should begin to accumulate again, and we could see sharp increases throughout the evening. 

EXTENDED FORECAST

TUESDAY, January 14:  After high AQI levels overnight, the pollution should be somewhat lower in the morning, but it is uncertain how much lower.  We could drop as low as Moderate, but it is more likely that the lowest level will be Unhealthy for Sensitive Groups.  Then between mid-morning and noon, PM2.5 levels should move up again fairly quickly.

WEDNESDAY, January 15:  From this far out, it looks like we could see some high pollution levels on Wednesday.  It is difficult to say how high, but it is likely to be Very Unhealthy or higher. 

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Saturday, January 11, 2014

It looks like Saturday will be a day for unhealthy air quality.  After the increase in pollution on Friday evening, we should see continued increases overnight, then some reduction in PM2.5 in the early morning hours.  After noon, the pollution may accumulate for a few more hours before the skies start to clear late in the evening.

EXTENDED FORECAST

SUNDAY, January 12:  We have a good chance of seeing clear skies between early and mid-morning on Sunday, but that trend should reverse in the afternoon, leaving us with higher AQI values in the afternoon and evening.

MONDAY, January 13: We could have slightly lower PM2.5 levels in the morning, but it is unlikely that we will see AQI values below Unhealthy for Sensitive Groups.  Then after lunch, we should see the pollution begin to accumulate again.

TUESDAY, January 14:  Tuesday looks like a repeat of Monday, with lower pollution levels in the morning then increasing pollution in the afternoon.

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Wednesday, January 8, 2014

Wednesday looks like a great day in Beijing!  We should see PM2.5 levels at Good/Moderate for nearly the entire day.  We will likely see PM2.5 increase in the evening, but it does not look like it will increase terribly quickly. 

EXTENDED FORECAST

THURSDAY, January 9:  Thursday will likely be worse than Wednesday for air quality, so we should spend a good portion of the day at Unhealthy AQI levels.  The general trend should be for increasing PM2.5, so we could see an AQI of Very Unhealthy by late evening. 

FRIDAY, January 10:  There are no signs of good air arriving on Friday, so we can expect AQI levels to be at Unhealthy or Very Unhealthy for the entire day. 

SATURDAY, January 11:  Saturday looks like a repeat of Friday, with the AQI at Unhealthy or Very Unhealthy for most of the day, but there is a good chance that we will see big increases in PM2.5 levels in the evening.

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Tuesday, January 7, 2014

On Tuesday, we should make it back to good air quality again.  We should see pollution levels dropping in the early morning hours, and we could drop into the Good/Moderate range as early as 5 or 6AM.  Although the clearing could happen a few hours later than that, once the pollution clears, we should have good air quality for the rest of the day.

EXTENDED FORECAST

WEDNESDAY, January 8:  We're looking for Good or Moderate levels for almost the entire day, then increasing PM2.5 levels in the evening.

THURSDAY, January 9:  Thursday will likely be worse than Wednesday for air quality, so we should spend a good portion of the day at Unhealthy AQI levels.  The best air quality of the day should come between late morning and late afternoon, and we could see the AQI dip down to Unhealthy for Sensitive Groups during that time.

FRIDAY, January 10:  There are no signs of good air arriving on Friday, so we can probably expect AQI levels at Unhealthy in the morning, then possibly increasing to Very Unhealthy in the afternoon and evening. 

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Monday, January 6, 2014

In the never-ending roller coaster that is Beijing's air quality, Monday should bring us to another peak in pollution levels.  Look for increasing pollution overnight and through about sunrise.  We should see PM2.5 concentrations level off or drop somewhat through the morning and early afternoon, then we can expect the air quality to begin to deteriorate yet again.

EXTENDED FORECAST

TUESDAY, January 7:  We should see poor air quality continue overnight, then it’s likely that we will see clearing skies sometime between late morning and mid-afternoon.

WEDNESDAY, January 8:  We should see air quality that is generally better than average for Beijing this time of year, likely with Good or Moderate levels for parts of the day.

THURSDAY, January 9:  Thursday will likely be a little worse than Wednesday for air quality, so it's likely that we will spend a good portion of the day at Unhealthy AQI levels.  The best air quality of the day should come between late morning and late afternoon. 

UPDATE – Our prediction with overlay of actual readings:

 

PM2.5 Forecast for Beijing – Sunday, January 5, 2014

Our constantly changing Beijing air quality is keeping us on our toes as it looks like we'll get good air quality for Sunday.  Sometime around or shortly after midnight, we should see PM2.5 levels start to drop, likely giving us Good/Moderate air quality around sunrise.  We can expect the AQI to stay low through early afternoon, then begin to increase fairly quickly through the late afternoon and evening.

EXTENDED FORECAST

MONDAY, January 6:  The air quality should continue to slowly deteriorate through Monday, leaving us with Unhealthy or worse conditions for the entire day, likely with the highest pollution of the day coming in the evening.

TUESDAY, January 7:  We should see poor air quality continue overnight, then it’s likely that we will see clearing skies sometime in the afternoon.

WEDNESDAY, January 8:  We should see air quality that is generally better than average for Beijing this time of year, and the afternoon should be particularly nice with Good or Moderate air quality.
