Another in what seems to be an unending parade of clipper-type systems will bring another round of light snow to northwestern Pennsylvania late this afternoon and this evening. Accumulations will be light with generally 1 to 3 inches anticipated. There won’t be much lake enhancement because temperatures aloft will only be marginally cold enough for a lake response.
The snow will taper to scattered snow showers after midnight tonight.
Wednesday will be mostly cloudy with a few scattered snow showers or flurries but little if any additional accumulation is expected.
The dry weather will last into Thursday morning. Then, yet another system will approach from the west spreading precipitation across the area Thursday afternoon. This time though, temperatures will be a bit milder and some areas could see a mix of rain and snow or even all rain.
Somewhat colder air will arrive Thursday night changing any rain or mixed precipitation back to snow. The snow is then expected to linger into Friday morning. This system will be one to watch as the models handle its development and evolution in very different ways. Thos differences will have major implications on our weather, especially with regards to snowfall amounts.
Once that system passes to our east, high pressure will build across the region for the upcoming weekend bringing us a brief break in our active weather pattern and milder temperatures.
