Forecast Discussion: Current Conditions: At 2 p.m. EDT this Monday afternoon, high pressure continues it's grip on the region with unseasonably hot conditions. Light wind flow expected over the next 24 hours will keep temperatures high and air quality will remain poor. In fact, an ozone action day will be declared for the area for the day Tuesday as the heat hangs on for another day. Light winds, recirculating air, sunshine, and unseasonable heat will bring ozone to the code ORANGE range for the area with temperatures maxing out in the middle and upper 80s. Fine particulate levels will also be in the moderate range for Tuesday as relative humidity will continue to be elevated. *** Extended forecast: A cold front will be moving through the area on Wednesday, but likely without rainfall. Ozone and fine particulate may lower some with increased mixing, but remain in the moderate range. A major change to more seasonable conditions is expected later on this week with much better air quality. High temperatures will return to the upper 60s by the end of this week.---McAuliffe
