Forecast Discussion: Current Conditions: Unseasonably cold air is entrenched into the region this Friday afternoon, and the winter-like chill will remain with us through most of the upcoming weekend, with tomorrow perhaps the coldest day we see until late next fall. The brisk northwesterly flow has kept fine particulate down in the good range, and this good air quality will also prevail most of the weekend. Tonight will be brisk and rather cold with a couple of snow showers. Low temperatures in the upper teens. *** Saturday's forecast: Very cold air remaining in place Saturday with strong mixing and vertical ventilation keeping PM2.5 levels in the good zone. A snow shower can still occur in the morning, then high pressure will build in during the midday and afternoon hours. In spite of sunshine returning, the mercury will rise no higher than the upper 20s. Quite cold Saturday night with a mostly clear sky and winds diminishing. Lows in the middle teens in the colder spots, with PM2.5 increasing, but remaining in the upper good range. *** Sunday's forecast: High pressure over the Mid-Atlantic region on Sunday will shift winds into more of a westerly direction, but mixing should be such that fine particulate does not rise significantly. Afternoon temperatures recovering into the lower to middle 40s thanks to increasing late March sun strength. *** Monday's forecast: A snow shower will start the day on Monday, with some sunshine returning in the afternoon. Robust west to northwest flow again will prevent PM2.5 from going into the moderate range. High temperatures mainly in the middle to upper 40s. *** Extended forecast: Springlike swings in temperatures are likely during the extended period. A weak area of low pressure moving to our north can bring a rain or snow shower early Tuesday, then high pressure builds in during the middle of next week with warmer air coming back in. PM levels will start the period in the good range, but then winds shift into more of a south to southwest direction in the middle of next week and bring in warmer and more humid air, so moderate concentrations are more likely by Wednesday and Thursday. A cold front will then bring in some showers by the end of the week.--McAuliffe
