Christmas Eve & Christmas Day Mostly Dry
Snow Likely Late Friday Into Early Saturday
Merry Christmas to everyone and on this Christmas Eve we are enjoying a lovely day of sunshine. A dry air mass is settling overhead and we have no weather issues to worry about right into the first part of Friday. Skies are partly to mostly sunny this afternoon. Winds are reasonable and not an issue. Radars are nice and quiet and temperatures are topping out in the lower 40s across Eastern Pennsylvania to Southern New England. We see no issues tonight and under clear skies, most lows will be in the 20s.

Christmas Day is shaping up to be a nice quiet day overall. There may be a few more clouds in the mix because we have a cold front that will pass through during the day. The front lacks moisture so there is no precipitation in the forecast, just a wind shift from west to northwest and then to the north as the front moves southward. Skies will be no worse than partly sunny and high temperatures will be in the low to mid 40s.
A very cold dome of high pressure will be building into Southeastern Canada and New England and northerly winds down the Hudson Valley will bring that cold air southward. Skies will be clear but by Friday morning, most lows will be in the teens and lower 20s. The high is key to the next Pacific system that heads from the Plains to the lower Great Lakes Friday. From there the low will be forced southward rather than eastward.
Snow will begin to spread southeastward from Western New York and Northern Pennsylvania and will be reaching Eastern Pennsylvania to Southern New England late Friday afternoon noon and evening. Cold air will be plentiful and temperatures will only top out Friday in the upper 20s to lower 30s. Snow is likely for much of Eastern Pennsylvania to Southern New England Friday night into Saturday morning.
This is the early snow forecast from the National Weather Service which shows that the axis of the heavy snow cuts right across Central and Northern New Jersey, Western Long Island, the Hudson Valley and much of Eastern Pennsylvania. These are early forecast amounts and are subject to change over the next 2 days. In areas in Southeast Pennsylvania, Southern New Jersey and west into South Central Pennsylvania, we could see sleet and freezing rain along with the potential for some serious icing issues Friday night. These areas will see less snow than areas to the north. Temperatures will be mostly in the 20s while the snow falls.
Low pressure tracks offshore Saturday and there may be some lingering snow Saturday morning before weather conditions improve. We should see temperatures back into the 30s Saturday. Sunday we will see early sunshine followed by arriving clouds. From the 20s in the morning we will reach the upper 30s and lower 40s for highs. An arctic front approaches Sunday night into Monday with more precipitation. This time around it may be more rain than anything else but we will have to keep an eye on temperatures inland for some potential for some sleet or freezing rain at the start. After this front passes, next week we will see a series of cold air masses coming into the Eastern US.
