Forecast Discussion: Current Conditions: At 2 p.m. EDT this Tuesday afternoon, an area of high pressure is producing plenty of sunshine, heat, and humidity across the area. Very light winds and limited cloud cover will continue to bring elevated air quality values over the next couple of days. As a cold front moves through later Thursday and Thursday night, improvements in air quality are foreseen for later on in the week. Tonight will remain warm and sticky with a mostly moonlit sky. Low temperatures only dropping down to near 70 degrees. Areas of fog are possible with fine particulate well into the moderate range. *** Wednesday's forecast: Hot and humid conditions will continue during the day Wednesday with limited cloud cover. Ozone values will rise rapidly as we move into the afternoon hours, and peak concentrations will be in the code ORANGE range in many locations. The humid conditions will also allow fine particulate to remain solidly in the moderate range. Afternoon temperatures will rise to the lower 90s. Warm and muggy again Wednesday night with lows in the lower 70s. *** Extended forecast: A cold front will approach later in the day Thursday, and bring thunderstorm activity out ahead of it Thursday afternoon and evening. The formation of this convection should keep ozone levels in the moderate range, and light winds and high humidity will cause fine particulate to remain in the moderate range. Afternoon temperatures will still rise to around 90 degrees. A new area of high pressure then builds in for Friday, and with a cleaner air mass, both ozone and fine particulate will average in the upper good to lower moderate range. Times of clouds and sunshine on Saturday with only limited afternoon and evening thundershower activity with a weak cool frontal passage late in the day. Both ozone and PM2.5 will average in the upper good to lower moderate range with temperatures near 90. Mostly sunny skies are expected for Sunday with temperatures in the upper 80s, with ozone and PM mainly in the lower moderate range. Another cold front will move in from the Midwest later Monday or Monday night. Air quality should be mainly moderate early next week, but increasing northerly flow in the middle of next week may bring improvements to the good range.---McAuliffe
