Clouds and an unseasonably warm 66F greeted early risers at Reagan National Airport on Thursday, but that mild start will not last. Cooler, blustery conditions are on the way, with showers moving in during the morning commute and a brief midday mix of rain and snow possible as temperatures tumble. Gusty northwest winds will make the afternoon feel colder and could leave a few slick spots on area roads.
Rain is likely before 11 a.m. Thursday, March 12, then is expected to flip to a rain-and-snow mix between 11 a.m. and noon, continuing on and off into the afternoon. Highs will top out near 47F before dropping into the upper 30s. Northwest winds are expected around 12 to 16 mph, with gusts up to 37 mph, and precipitation chances peaking near 90 percent. New snow accumulations outside the mountains should stay light, generally under a half inch, though heavier, wet bursts could briefly cut visibility. According to the National Weather Service Baltimore/Washington, the Blue Ridge has the best shot at measurable snow.
Where Snow May Stick
The Blue Ridge and Skyline Drive are the main areas to watch, with forecasters calling for 1 to 3 inches there and a Winter Weather Advisory in effect for higher elevations Thursday, March 12. Outside the mountains, any accumulation should be patchy and quick to melt on roads and sidewalks. This post updates our March 11 coverage earlier forecast because advisory language and mountain totals were added overnight.
Friday Wind And Fire Risk
Another strong cold front will sweep through on Friday, March 13, bringing robust southerly winds ahead of it and gusts that could again flirt with advisory levels in exposed areas. Low humidity paired with those gusty winds will raise fire-weather concerns in drier inland valleys, where relative humidity is expected to dip into the 20s in some spots. Winds should shift and ease Friday night, with temperatures moderating as the weekend approaches.
Commute And Boaters
For commuters, expect wet roads and the possibility of brief slushy patches through the afternoon. Slow down, give yourself extra travel time, and watch for slick bridges and shaded areas where slush can hang on. On the water, mariners should follow Small Craft Advisories into the evening on parts of the Bay and make sure loose gear is secured before heading out. We will update this post if any watches or warnings are expanded.
