The bad news is that this will "squeeze" the smoke into western and central Pennsylvania, with widespread Very Unhealthy levels of 250+ expected for areas such as Pittsburgh, Erie, State College, Gettysburg, Harrisburg, York, and Lancaster for the afternoon and evening hours.
➡️If you live in zones A through C, it is highly advised to cancel outdoor plans for Friday due to unhealthy to hazardous air expected. The smoke will shift back east on Saturday, but there is still some uncertainty on how bad it is, as we will see widespread showers and storms that will help to cleanse out the air.
