Weather Outlook for the Week of January 6, 2026

A quick-moving disturbance will exit the region early Wednesday, bringing an end to any precipitation as high pressure builds into the state. Temperatures will be mild with highs in the 40s and 50s through the end of the week. Parts of southeastern PA may even reach the low 60s by Friday afternoon as a low approaches the state from the west. Rain showers and even a few rumbles of thunder will develop early on Friday over western PA and move east through the rest of the state during the day. On Saturday, a second low crossing the Great Lakes will bring periods of rain throughout the day. A strong front will usher in colder air, along with the potential for additional showers and storms, later in the day into Sunday morning. As the front exits the state, any rain showers will change to snow showers as temperatures drop into the upper 20s to mid-30s by later Sunday evening, and some lake-enhanced precipitation develops through the start of the new work week. Any lingering precipitation will end by midday Monday as temperatures rebound to above normal levels for Monday and Tuesday of next week as another ridge of high pressure builds over the eastern U.S. 

Long-range guidance indicates a slightly milder than average remainder of January with precipitation near seasonal levels.
