February 4 at 9:45 PM – Every time I look at the latest short range high resolution radar, it keeps pulling the snow farther west. It doesn’t look like much on the map this evening, but it will develop right on top of us between 1 AM and 3 AM Friday. We will get snow, but high intensity will be needed to overtake the warm ground and temperatures that may remain near or above freezing. Yes, it can snow with warmer air, thanks to very cold air producing the flakes at cloud level.
This morning it looked like maybe flurries could skirt as far west as Annapolis or Baltimore. Now it appears the light snow pulls back past Frederick. This is all in response to the front on the coast stalling (as I mentioned earlier it fit the same reasoning the warm air never arrived yesterday and why the rain lasted longer). Now upper lever energy and cold air from the Great Lakes is puling this system back and more of us will wake up with snow.
Our latest Winter Weather Advisory map is below. Before looking at the latest timeline, I want to remind you what I said in my last report: Temps will be marginal, so expect a slushy, sloppy snow. Plus the ground is still warm as evident in melting over 2 feet of snow this week. So some flakes will be wasted to cool the ground down. But the overnight snowfall will help your FITF
This will be heavy in the morning near the Bay to the coast. I-95 travel will be impacted. I do expect school delays… and maybe more impact on the Delmarva where it will last all morning. The top snowfall will be on Delmarva between Easton and Dover. See the latest snowfall projection below.
Rain is spreading north, and will expand back west to the mountains. I wanted to pick this up where it gets interesting… at 3 AM
