Double trouble? Chance for snow Thursday morning and Saturday in D.C. area.
Neither snow threat looks particularly serious at the moment, but both are worth monitoring.
A snowy month in the D.C. area could get a little snowier over the next five days. Two periods of snow are possible, the first Thursday morning and the second Friday night into the weekend.
Thursday’s snow, which will start as rain, could produce slick roads for the morning commute, especially in colder areas north and west of the Beltway. The weekend storm has a chance to be more significant, potentially tapping Atlantic moisture while drawing in very cold air.
However, neither of these snow chances are a lock to produce meaningful accumulation. Temperatures may not cool down fast enough before the snow ends Thursday for much to stick. Meanwhile, the weekend storm could miss us to the southeast.
In other words, both storm systems have the potential to be disruptive, but there’s also the possibility that neither delivers.
Snow timing and amounts
Precipitation could begin as early as Wednesday night after 10 or 11 p.m., probably starting as rain and with temperatures near 40. The rain could change to snow between predawn and sunrise Thursday from northwest to southeast across the region. Any snow should shut off between midmorning and midday.
This seems like the kind of event that could produce a coating to an inch or so in the immediate D.C. area and perhaps 1 to 2 inches in our colder areas to the north and west, but we will refine this outlook and produce a forecast accumulation map Wednesday.
Here is what we view as the chances for different amounts of snow in the District:
Chance of at least one inch: 40 percent (60 percent north and west of the Beltway, 30 percent south and east)
Chance of at least three inches: 20 percent (40 percent north and west of the Beltway, 10 percent south and east)
