Lehigh Valley Weather

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.

Forecasters have turned their attention to the end of next week, saying most model guidance indicates a storm system developing and affecting the East Coast — including the mid-Atlantic —around Thanksgiving Day and into Black Friday.

The drought is far from over, but enough precipitation has fallen to boost the confidence of state officials when it comes to outdoor fires.

After a steady – but not soaking – overnight rain, the area remains on track to break a pair of records that have stood the test of time. But more precipitation is on the way, including snow.

The National Weather Service has issued a winter storm warning in effect from Thursday afternoon through Friday afternoon for Carbon and Monroe counties in an "elevation-dependent system."

Forecasters are watching a storm system expected to rapidly intensify Wednesday night into Thursday. It could bring more than an inch of rain to the area, and even snow in some locations.

The National Weather Service in Mount Holly issued the warning for gusty winds and low relative humidity, which is in effect from 7 a.m. to 6 p.m. Saturday.
