It will still be windy all day long. Temperatures start off close to 60 and fall in the 40s in most places by mid-afternoon.
The wind, which will be shifting to the southwest and eventually the west later Thursday, will make it “feel even colder” late in the afternoon, with the wind gusts as high as 40 mph. Blustery and much colder conditions are going to prevail Thursday night and Friday. It appears at this juncture that the best upperlevel support for some steadier snow will be “very close to” Baltimore late Thursday (this is because a very strong impulse of jet stream energy diving out of the north and west will be pressing across Maryland, Delaware and South Jersey late Thursday and Friday morning).
The arrival of some chillier air later will become “reinforced” late Thursday and Friday by a strong parcel of energy in the upper atmosphere. So, we expect winds gusting to near 35 mph Friday, temperatures mostly in the upper 30s and lower 40s, and that morning snow shower, which could result in some SLICK SPOTS.
It’ll stay cold over the weekend, and temperatures both Saturday and Sunday should be no higher than the 30s in most places. The “next challenge”(as our p.m. shift colleagues described it Wednesday) will be to determine what happens when a “Clipper” type disturbance rolling out of the Great Lakes Saturday night slides to the East Coast. Snow showers, or just a “plain old period of steady snow” is possible late on Saturday night or Sunday, and temperatures on Sunday afternoon could be just high enough to support some rain as well as a wet, slushy snow. Most of these details are going to be ironed out over the next couple of days.
Have a good day!!!
