Forecast Discussion: Current Conditions: As of 2 p.m. this Monday afternoon, there is sunshine aplenty across the region, but things remain on the cool side with temperatures barely reaching 70 in many areas. The abundance of cool and dry air is keeping fine particulate down in the good range. A cold front will pass through later on tonight with a couple of showers. While it may warm a bit later on this week, temperatures are expected to remain at near normal levels for this point in the month. *** Tuesday's forecast: Winds will shift into a northwesterly direction for the day Tuesday with high pressure rebuilding into the area from the Midwest. While fine particulate starts the day in the moderate range, there will be enough dry air to drop these levels into the good category by the afternoon as mixing increases. Mostly clear and cool Tuesday night with lows in the middle 40s in the cool spots. *** Extended forecast: We will be in a mostly dry weather pattern later this week into the weekend. A weak front may kick off another shower late Thursday night into Friday morning, but other than this, high pressure should control the weather picture. Good air quality should continue on Wednesday. Very light east winds on Thursday might bring PM2.5 up a little, but still in the upper good range. A reinforcing shot of drier air Friday into the weekend should result in low concentrations of fine particulate once more.---McAuliffe
