After periods of steady rain overnight, the last of the rain showers will pull out of the region Wednesday morning.
Bring the umbrella for the morning commute, but you won’t need it for the rest of the day. Rain showers end by mid-morning, as the cold front passes. Then, two things will happen.
It will become sunnier. We should see breaks of sun midday and a mostly sunny sky for the afternoon (more clouds along the coast). You will also feel the chill in the air as we say hello to winter.
Highs Wednesday in the upper 40s are seasonable for this time of the year, but given the recent mild stretch of weather, you will notice the chill. We will need winter jackets for the bus stop, as we start out in the mid to upper 20s Thursday morning.
Thursday will be much like Wednesday afternoon, crisp and mostly sunny. However, a low-pressure system makes the weather interesting for the weekend.
So, yes, snow is on the table! Many of you snow lovers have been tracking this for quite a while. In fact, we have been eyeing mid-December as cold and stormy since mid-November. Here is the setup.
Low pressure rides along the eastern edge of the high pressure Friday, sliding it up the East Coast. The clouds will thicken. It will be cold, too, with highs about 40. This system has plenty of moisture with it. However, high pressure has plenty of dry air, too, setting up a battleground over New Jersey.
Friday afternoon into Saturday morning is the best time for precipitation, likely starting as a rain/snow mix, before going to all snow. This will be a rare day because the best places for snow will be along the shores. That is where I am confident about flakes flying. The farther west you go, the better chance the dry air eats up the moisture.
How much snow? A couple of inches at the shore, at most. Helping accumulations is that any snow would fall overnight. However, again, there is potential for zero snow anywhere, or that it will not stick.
The rest of Saturday will be chilly, but dry.
If you stay warm, go out and enjoy all of the holiday parades.
Sunday will then have a clipper system move in. Clipper systems run low on moisture, but usually bring lots of cold air. If we miss snow Friday to Saturday, we will not have to wait long for our next chance. However, any snow showers here would be light, dry snow and failing to accumulate much.
