Forecast Discussion: Current Conditions: At 2 p.m. EDT this Wednesday afternoon, plenty of cloudiness with a few showers are moving through the area. With the clouds and cool air, ozone and fine particulate remain in the good range. Showers will continue across the area this evening, then a steadier rain is likely later on overnight. *** Thursday's forecast: A large area of low pressure moving across Pennsylvania will bring rainy periods to the area into the early afternoon Thursday, with a thunderstorm possible in the afternoon. Considerable cloudiness and heavier rainfall will keep fine particulate down inside the good range. Breezy Thursday night with mostly cloudy skies along with a shower or two. *** Extended forecast: Variable cloudiness and breezy for Friday with a shower or two possible. A decent amount of mixing as well as lots of clouds will keep air quality good. Saturday will bring more clouds than sunshine, but most all of the day should be dry. Another episode of rain is in store for Sunday with the next frontal system, and a thunderstorm is also possible. Cloudy to partly sunny Memorial Day with a shower still possible, but most of the day should be rainfree. Air quality will remain good over the holiday weekend.---McAuliffe
