In the wake of Wednesday’s very minor winter weather event, some paved surfaces that became wet late Wednesday could be slick for a while Thursday morning.

Most temperatures will be starting off near or slightly below freezing, but clouds that are tending to linger early Thursday morning should break for a good deal of sunshine from mid-morning on.

Highs  should be in the mid and upper-40s, and the night will be relatively clear. Mild weather will be returning Friday, with many thermometers reaching 50 in the bright sunshine.

Our next “weather of consequence” is headed our way late Friday night and Saturday.  The global models are still showing that the Northeast and portions of the mid-Atlantic states will be getting impacted by a synergy of two features: an arctic cold front, and a wave of low pressure that will be developing early Saturday in the waters located off the Jersey Shore.

First of all, we will want to point out that there will be no impact on Friday evening’s rush – because precipitation should start to break out sometime after midnight.  Secondly, we should also be mindful of the fact that some relatively mild air always tends to get “squeezed out” ahead of arctic fronts.

Therefore, it wouldn’t surprise us if several thermometers were in the upper-30s to around 40 late on Friday night when precipitation starts, and that could lead to some rainfall at the onset, as well as snow.

But, as colder air manages to spread out across the coastal plain early Saturday morning, all forms of precipitation should end as some snow or flurries.

There are several “ideas” being tossed around about this event. Some forecasters believe that there will just be a 20 or 30-minute snow squall in the big, coastal cities, which could drop a quick coating to an inch before moving on — and there are others who believe that the eventual development of that low pressure system offshore may enhance our snowfall for a few hours longer.

Either way, we should be addressing the potential for some slick spots around here for a while on Saturday morning.
