Not much change with the forecast. Looks like timing wise-it may start Thursday night
around 10pm or so and be done way before you wake up lol...so alot of people may not even see it snow. Accumulation wise...we are talking 1-3 inches since its such a quick mover. Maybe someone lucks into 4. Been a pretty wild winter so far. Warm and precipitation less December(we couldnt even buy rain). Snowy and Cold January so far(except for Jan 1). Fredericksburg, Va has more snow than Boston,Philly,NYC and Hartford Combined. Looks like for the most part, we will remain in a wintry pattern for the next couple weeks with a few warm shots here and there. Here is the 6z eurp..looks a bit over done but 2-3 inches from this "storm" isnt out of the question.
(from CWG)
A few inches of snow possible Thursday night, with slick roads Friday morning
Widespread amounts of 1 to 3 inches are expected with a little more possible locally
A fast-moving storm system will sweep through the Mid-Atlantic and Northeast on Thursday night, probably laying down about one to three inches of snow in the Washington and Baltimore areas.
It’s not out of the question that a few areas will see a little more or a little less, but this event will not be nearly as heavy as Monday’s severe snowstorm.
The snow should start between 8 p.m. Thursday and midnight, and end before sunrise Friday. Because temperatures will fall as it snows, roads are likely to become quite icy, causing delays and cancellations Friday morning.
Amounts
Computer models suggest this storm could produce as little as a dusting of snow and as much as six inches, but they generally show two or three inches falling in the region. The models vary as to what areas will see the most snow; some show the heaviest amounts north of the District, while others put them to the south.
Our snowfall map, showing widespread amounts of one to three inches, represents a blend of the model projections, as it’s too early to know what areas will be hardest hit or just fringed by this system.
There is a chance of a locally heavy corridor of snowfall that produces up to three to six inches, but it will be Thursday before we have a better idea of where that might set up.
The National Weather Service’s snowfall map, pictured below, shows the potential for widespread amounts of two to four inches, which is a little higher than we’re comfortable predicting at this point.
Snow timing and temperatures
One of the reasons our snowfall forecast is a bit conservative is because temperatures will be above freezing in some areas when the snow first arrives, probably in the mid-30s in the immediate area (although colder to the north and west) after highs in the low 40s Thursday afternoon. Thus, some accumulation may be lost to melting.
After midnight, however, temperatures should drop below freezing areawide, causing roads to ice over and become snow-covered.
8 p.m. Thursday to midnight: Light snow develops west to east, possibly starting briefly as rain in southern Maryland. Temperatures: 31-37 (northwest to southeast).
Midnight to 3 a.m. Friday: Snow, moderate to possibly heavy at times. Peak rates of one inch per hour possible. Temperatures: 28-33 (northwest to southeast).
3 a.m. to 6 a.m. Friday: Snow tapers off. Temperatures: 24-29 (northwest to southeast).
