AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)

Forecast Discussion: Current Conditions: At 2 p.m. EDT this Friday afternoon, a strong area of high pressure, both at the surface and aloft, is bringing a continuation of summerlike conditions across the area. Very light winds and plenty of sunshine have brought fine particulate to the moderate range. Ozone levels will also increase to moderate this afternoon in parts of the area. For tonight, we will have a mostly clear sky as low temperatures fall into the upper 50s. *** Saturday's forecast: Mostly sunny skies with unseasonably warm air continues for Saturday, and with a light northerly flow limiting mixing, both ozone and fine particulate will go low moderate. Afternoon temperatures in the middle 80s. *** Sunday's forecast: Sunny and rather warm for the day Sunday. Mixing should be just enough to prevent either ozone or fine particulate from rising above the moderate range. High temperatures in the middle and upper 80s. *** Monday's forecast: A little more humid with summerlike warmth will start off the week for Monday, and with emissions increasing, we will have to watch ozone levels for possible USG concentrations. Fine particulate will remain moderate with elevated humidity. *** Extended forecast: Unseasonably warm weather will start off the extended period, with a cold front slated to move through by the middle of the week. Later on in the week, a much cooler and stronger northwesterly flow will bring improvements in air quality along with a return to temperatures more typical of early fall.---McAuliffe
