Forecast Discussion: Current conditions: At 2 p.m. EDT this Thursday afternoon, warmer air was streaming northward out ahead of a cold front moving through western Pennsylvania. This front will pass through our area early tonight, and bring some rain and even a thunderstorm. The warmer and more humid air with light winds was keeping fine particulate in the moderate range. Improvements in air quality will occur over the next 24 to 36 hours, but with much colder air coming in. Much colder later on tonight with some wet snow possibly mixing in with any lingering rain. Low temperatures will plummet into the middle to upper 30s towards dawn. *** Friday's forecast: Clouds and even some light rain mixed with snow will linger into the morning hours on Friday, otherwise brisk and chilly with clouds hanging tough into the afternoon. High temperatures will only reach into the upper 40s, and with a stronger northwest wind, fine particulate concentrations will fall into the good range. Clear to partly cloudy and cold Friday night with temperatures falling into the middle 20s. *** Extended forecast: Good air quality will continue on Saturday with very dry and cold air in place. High temperatures will not get above the 40 degree mark despite sunshine. High pressure will then shift south and east of us Saturday night into Sunday, allowing for winds to shift into the west and southwest. Higher levels of fine particulate will then occur, and some locations will rise into the moderate range. Still on the chilly side on Sunday with highs no better than the middle to upper 40s. A series of weak systems will then affect us for the early part of next week, and with the progressive pattern, good air quality is expected. Turning a little milder towards the middle of next week, but with temperatures still only near normal to close out March.--McAuliffe
