Forecast Discussion: Current Conditions: At 2 p.m. EDT this Tuesday afternoon, a northwesterly flow has resumed across the region in the wake of a cold front which moved through earlier today. While a lot of areas are in the moderate range for fine particulate at present, these levels should drop as the afternoon progresses. However, the PM concentrations will rise once again later tonight as winds decrease and mixing is more limited. Lows overnight in the middle 40s in the cooler spots. *** Wednesday's forecast: High pressure will bring a good deal of sunshine for the region on Wednesday. With winds and mixing remaining light, fine particulate will drop some by afternoon, but may end up averaging in the lower moderate range. Afternoon temperatures will rise into the lower to middle 70s. Another cold front will cross the area Wednesday night, but is not expected to bring any rainfall. *** Thursday's forecast: Another area of high pressure will build southwward from Ontario on Thursday with slightly cooler air and northerly winds. This should bring PM down into the good range with highs in the lower 70s. *** Extended forecast: Dry weather will continue across the area into the upcoming weekend with a little bit of a warming trend. Higher humidity levels will also be evident by late Saturday into Sunday as winds shift into the southwest. Good air quality should continue on Friday with low humidity, but then more moderate levels of PM are possible over the weekend. High temperatures may approach 80 degrees or perhaps a little higher on Sunday if there is enough sun. Another cold front will then bring another chance for showers Sunday night into Monday along with cooler temperatures.---McAuliffe
