High pressure will build across northwestern Pennsylvania today and tonight bringing and end to the light snow and gracing the region with a brief period of dry weather. High temperatures today will reach the mid 20s with lows tonight in the teens.
The high will move off to our east on Thursday as a pair of low pressure systems to the west approach. One low will track eastward into the Great Lakes while the other will track from the southern Plains into the Tennessee Valley. Clouds will increase and there could be a few rain or snow showers during the afternoon. High temperatures will climb to the mid 30s.
Thursday night and Friday, the pair of storm systems will track east of us and phase into a single powerhouse storm near the New England coast. Colder air will be pulled southward across northwestern Pennsylvania Thursday night changing all precipitation over to snow. There could be some accumulations. Lows will dip to the mid 20s.
The snow will continue into Friday, before gradually tapering off Friday afternoon. Additional accumulations are possible. Highs on Friday will rise to around 30 degrees.
High pressure will bring fair weather back to the area over the upcoming weekend with dry weather and moderating temperatures expected.
