Forecast Discussion: Current conditions: At 2 p.m. EDT this Thursday afternoon, dry air remains in place across the area with high pressure retreating off of the east coast. The dry air continues to bring good air quality. An area of low pressure was located over Illinois. This low will move to the east over the next 24 hours, and will draw copious amounts of moisture into it as it does so. For tonight, we will have an overcast sky with showers this evening, then a steadier rain later on tonight. The rain may start as some sleet or wet snow in the Poconos. Low temperatures will fall back to the upper 30s overnight. *** Friday's forecast: Low pressure moving into the eastern Ohio valley will bring a brisk south to southeast wind for the day Friday with rain, heavy at times due to orographic forcing. Plenty of rainfall washout will keep PM2.5 concentrations low Friday. Chilly with temperatures only reaching into the middle to upper 40s. Rain will taper off to showers later Friday night with low pressure redeveloping over the Delmarva peninsula. *** Extended forecast: Low pressure will pull away from the east coast on Saturday, but the day will remain rather cloudy with a couple of morning showers. Brisk north to northwesterly winds will keep fine particulate levels low. Our weather will improve for Sunday as high pressure builds in from the west, and brings more sunshine. Plenty of dry air will mean low levels of particulate matter again. The next storm system coming out of the Midwest will affect us later Monday night into Tuesday with another round of rain, followed by a return of dry weather for Wednesday. Air quality will remain good through the period.---McAuliffe
