![]() ![]() These are the areas most likely to see morning commute impacts and possible school impacts as well. ![]() Although it is likely to initially melt on contact, it is also likely that some spots will see a steady enough snowfall to begin accumulating on grassy areas and possibly untreated roadways as well. I-81 Corridor/Western VA/WV Panhandle/Northern MD: While precipitation may initially begin as rain, sleet, or even freezing rain, our weather models try to transition over to snow pretty quickly across the highlands with enough cold air in place in the upper levels of the atmosphere. Wet roads will likely be the story of the morning commute - not snow covered roads. We do NOT anticipate any accumulations by sunrise in these locations. Higher elevated areas of Montgomery, Loudoun, and western Howard counties could see more sleet mixing in because these are areas that tend to just naturally run several degrees colder than the city. ![]() I-95 Corridor/D.C./Central MD/Northern VA: Current guidance suggests a rainy start in most of Northern Virginia and the immediate D.C. There is currently a good agreement between the weather models that we'll see surface temperatures above freezing and enough warm air aloft that the event should begin as mostly rain - although we can't rule out sleet mixing in in a few spots.

Spotty rain showers cannot be ruled out south or west of town, but this should be the exception rather than the rule. Some early sunshine will give way to more afternoon clouds ahead of the storm, but most of our area will remain dry through the evening hours. Region-Wide: No concerns about winter weather Monday.

The second round of wintry precipitation will come through late Tuesday night through Wednesday. The first round of wintry precipitation Tuesday will bring slippery travel north and west of the District, where a Winter Weather Advisory is in effect for a snow and sleet mix. While the event itself will likely appear to be one prolonged event, it is actually two separate storms running consecutively to one another: To put it lightly, we have one of the trickiest forecasts in recent memory coming up over the next couple of days here in the D.C. Funny enough - last year's biggest snow of the season also came in March and the upcoming storm is expected to be similar in that it may be more of a "messy mix" than any single type of precipitation. ![]()
