Forecast Discussion: Temperatures and humidity will begin to creep up on Wednesday, but it will still be a sunny and pleasant late summer day. Although the air mass in place continues to be quite clean, recirculating flow aloft and calm winds though the morning will allow ozone precursors to accumulate, setting the stage for ample ozone production in the afternoon. As a result, ozone should rise well into the Moderate range. Particles will also rise in response to the morning stagnation but remain in the Good range in the relatively clean air mass. **Extended Forecast: A shift to onshore (south/southeasterly) flow on Thursday will push ozone slightly lower into the Moderate range and particles a bit lower into the Good range. Friday will be hot and humid ahead of an approaching cold front. Ozone will rebound to the top of the Moderate range, and particles will rise to the low Good/Moderate threshold. -Huff
