Another clear and cold night is underway, but it won’t be as cold as it was for many of us last night.  Mainly clear skies and a fresh snow pack allowed temperatures to drop into the single digits across the Lehigh Valley and Poconos early this morning, with near to below zero cold in parts of northwestern New Jersey. Usually, a calm wind is required for perfect radiational cooling conditions and the coldest temperatures, but even with a light breeze persisting overnight, single digit cold and even some below zero wind chills were achieved. Plenty of sunshine allowed for some temperature recovery on Wednesday, but it was still a rather cold and breezy day with highs around 30 to 35 degrees for most of us, except the Poconos and higher elevations of northwestern New Jersey which remained in the 20s.

But now, we have bottomed out and have nowhere to go but up, and up we will go especially by the weekend as 50-degree warmth is in the forecast and a second January thaw arrives. While the weekend looks dry, some wet weather is likely on the way early next week. Despite the raindrops, the milder than average temperatures should remain in place through Tuesday.

Winds will diminish overnight as skies remain mainly clear, which will allow for another cold night across the area but not quite as cold as last night. Lows should drop into the mid-teens for most of us, by the far the coldest night of an increasingly mild forecast.

That warm up will be slow at first as the cold only gradually eases, but that process will begin on Friday. Expect another mostly sunny day as high temperatures inch back above freezing to around 35 to 40 degrees by afternoon. Winds will be lighter as well, which means there will be less of a wind chill on Friday. Skies will remain mainly clear into Friday night, with lows dropping into the mid 20s as the nights also become less cold going forward.

On the weather map, we'll watch a large area of high pressure over the southeastern United States slowly slide off the coast. As it does so, our winds will shift around from the west and southwest, and the warming trend will become more noticeable and pronounced.  Highs will climb to near 50 degrees on Saturday with mostly sunny skies, and Sunday also looks at least partly sunny with highs in the upper 40s. So while we aren't expected to get as warm as the first thaw when we broke record highs in the mid 60s late last week, we're also not expecting any soaking rain to accompany the warmth, at least not initially. That means the weekend will be mild and dry, including for the NFC Championship Game in Philadelphia Sunday evening. 

Early next week, things turn unsettled as we'll have a pair of fronts to contend with. On Monday, we'll watch a warm front lift north through the area, bringing clouds and a little rain or drizzle. With the damp weather and a wind that will shift from the east and southeast, it won't be quite as warm as the weekend was, but highs are still expected to be on the plus side of 40 degrees. Steadier rain will arrive later Monday night into Tuesday morning as a cold front arrives, bringing one final surge of milder air out ahead of it as high temperatures make another run to near 50 degrees.

Behind that front, some cooler air will arrive on brisk westerly breezes, but it still won't be all that cold. Expect partly sunny skies through the middle and end of next week and highs still a touch above seasonable levels for mid-January, with highs expected to be around 35 to 40 degrees and overnight lows in the 20s. No big snows or bitter blasts of arctic cold are in sight through next week.
