Sunday's snow will probably be more cosmetic than disruptive in the D.C. area.
We can’t rule out an inch or two, but a coating or so is more likely.
The Washington region will see the weather flip from 60 degrees to snow in less than 24 hours this weekend. But this latest blast of wintry weather, while jarring, shouldn’t be too problematic for those attempting to get around on Super Bowl Sunday.
Although some areas, especially south of the District, could see a quick inch or two of snow early in the day, other areas may not see much more than melting snowflakes.
Most of the snow should exit by midmorning Sunday. In places that do see a quick burst of snow early in the day, we can’t rule out some slick spots before conditions gradually improve. Most areas should be clear leading up to the evening.
“Sunday’s snow looks like a minor event, at most, with snowfall limited to a coating to an inch or two wherever a consolidated stripe of snow develops early Sunday morning,” said Wes Junker, Capital Weather Gang’s winter weather expert. “The system never taps into Atlantic moisture, so snowfall should be light.”
