The worst air quality this week is present this morning in much of South Central & Southeast PA (AQI 300-500). Fortunately, the plume of thick smoke causing this will drift south today and exit the area by the afternoon. We won't see an immediate sizable improvement in air quality though, more so a gradual change. More smaller plumes of smoke are likely this afternoon into tonight.

We expect to be done with this nightmare (for now) by Saturday. But there will continue to be the chance for smoke in the next several weeks as these fires continue. We're crossing our fingers on the models continuing to show multiple opportunities for rain next week.

Highs today will actually be fairly cool relative to average, a very nice day minus the air quality situation.

Here's the HRRR showing this morning's smoke followed by the smaller smoke plumes and then the gradual exit.
