Forecast Discussion: Current Conditions: At 2 p.m. EDT this Friday afternoon, high pressure nosing it's way in from the Midwest is bringing plenty of sunshine across the area. Brisk west to northwesterly breezes are bringing good air quality with ozone and fine particulate. The good air quality should continue into the day Saturday, but then as the air turns more humid later on in the weekend, pollutant concentrations will be on the increase. Mostly moonlit and pleasant tonight with lows in the lower 60s. *** Saturday's forecast: Sunshine and some clouds Saturday. An adequate amount of low level mixing should keep fine particulate and ozone in the good range. One or two spots might see a thundershower pop up, mainly across northern parts of the partnership area. Afternoon temperatures reaching in the lower to middle 80s. Mostly clear for Saturday night with lows in the lower 60s. *** Sunday's forecast: Periods of clouds and sunshine with increasing humidity Sunday. Highs in the middle 80s, with fine particulate and ozone on the rise, perhaps to the lower moderate range as winds turn into the southwest. *** Monday's forecast: A cold front moving through the area Monday will bring showers and a thunderstorm with it. High temperatures will reach into the middle 80s with more clouds than sunshine. Ozone will thus be limited to the good range, while things remain humid enough to keep fine particulate in the moderate zone. *** Extended forecast: Cooler and drier air will bring improved air quality for the area in the middle of next week. A northwesterly flow Tuesday into Wednesday should keep fine particulate and ozone down in the good range. Weak disturbances in the west to northwest flow might bring a shower from time to time late Wednesday or Thursday, but exact timing is uncertain at this point.---McAuliffe
