Wednesday never brought us the clear air we were hoping for, and Thursday's forecasts indicate that we will probably be seeing our third day in a row of rainy, polluted air. You can expect the PM2.5 levels to remain at Unhealthy or the lower range of Very Unhealthy for the entire day; there may be some variation, but it is very difficult to predict that hour-by-hour (as we've seen the last two days).
