The National Weather Service issued a winter weather advisory mid-Sunday afternoon, warning of potential slippery conditions as mixed precipitation moves through the Lehigh Valley into early Monday morning.
A system arriving Sunday night could bring a period of snow and ice to the area before a changeover to rain but “there remains considerable uncertainty with the details.”
The rainfall is expected to be heaviest Wednesday afternoon and evening as a cold front approaches, with forecasters not ruling out some rumbles of thunder possible in the Lehigh Valley.
Highs in the 30s and lows mainly in the 20s are forecast for the weekend and well into next week, which could be jarring on the heels of one our warmest Novembers on record.
Guidance “continues to trend towards a warmer solution for Thursday’s storm,” the National Weather Service said, meaning it's going to be a wet, not white, Thanksgiving.
