Forecast Discussion: Current Conditions: At 2 p.m. EDT this Friday afternoon, high pressure building in from the nation's midsection is bringing warm, but less humid conditions with a good deal of sunshine. A clean, dry north to northwesterly flow is bringing low levels of fine particulate and ozone. Over the next few days, humidity levels will slowly begin to rise, and there will also be a corresponding increase in fine particulate and ozone. Mostly moonlit tonight with lows in the lower to middle 60s. *** Saturday's forecast: Dry weather will continue for the most part on Saturday. A weak disturbance can produce a late day thunderstorm in one or two spots. Afternoon temperatures in the middle and upper 80s. Ozone will remain in the upper good range, and fine particulate will also average upper good overall. Clear to partly cloudy Saturday night with lows in the middle 60s. *** Sunday's forecast: Very warm and more humid for the day Sunday with limited convection. Both ozone and fine particulate may rise into the lower moderate range. High temperatures in the upper 80s with more sun than clouds. *** Monday's forecast: A cold front approaching from the west later Monday into Monday evening will spark thunderstorms during this period. Ozone levels might go into the moderate range where thunderstorms are delayed, with fine particulate well into the moderate range. High temperatures near 90 degrees. *** Extended forecast: Cooler and drier air will move in for the middle of next week, with breezy conditions and a partly sunny sky Tuesday into the day Wednesday with good air quality and temperatures averaging a few degrees below normal. A couple of showers are possible Thursday as a wave of low pressure moves along a stalled front in the Mid-Atlantic.---McAuliffe
