Today: Rain and snow end early. Blustery, possible p.m. flurries. Highs: 35-40
Tonight: Snow shower possible early, gusty winds. Lows: 16-22
Tomorrow: Sunny start becoming cloudy by afternoon. Highs: 35-40
As a fast-moving storm fires up right on top of us, rain could end as a bit of snow early this morning in parts of the region. The precipitation shuts off quickly, but the cold, blustery conditions mark a radical change from the past two days. For those missing our record warmth, you don’t have long to wait. 70s could return on Sunday!
Today (Thursday): The main point for the rest of Thursday: it’s windy! Gusts are pushing past 40 mph, so bundle up. Clouds persist through the day, and a few quick-hitting snow showers could redevelop as it wears on. It’s not out of the question one or two of these produces briefly heavy snow that reduces visibility and quickly coats the ground before zipping away. Highs actually occurred at midnight with temperatures holding in the 30s through the afternoon. Confidence: Medium
Tonight: Winds are still brisk through the evening from the northwest gusting to 25 mph. A few lingering snow showers can’t be ruled out. Skies clear late as winds subside and lows drop to mid-teens northwest of town and upper teens to lower 20s in the metro area. Confidence: Medium-High
Tomorrow (Friday): Sunny skies and light winds are a marked improvement, but temperatures are not. Highs only reach the mid-30s to 40 as Arctic air holds its ground. Clouds build back into the area by afternoon. Confidence: Medium-High
Tomorrow night: The clouds are likely to hold into the evening and could hamper viewing of the eclipse of the full “snow” moon. Skies are likely to clear later at night. Temperatures barely slip as southwest winds are already at work warming up the area. Lows hold in the upper 20s to lower 30s. Confidence: Medium-High
Saturday, the warm-up begins in earnest despite a fair amount of high clouds. Highs climb to the mid-to-upper 50s. This should feel just fine as winds are generally light. Clouds persist through the night, and lows only fall to the mid-to-upper 40s. Confidence: Medium
A very light shower is possible most any time on Sunday as warm moist air surges into the area, but measurable amounts are unlikely. Clouds dominate holding highs in the low-to-mid 60s, but if there are enough breaks in the clouds, lower 70s are quite achievable. A weak cold front pushes across the area overnight setting off more light showers. Lows range through the 40s. Confidence: Medium
Monday is not so bad with clearing skies for a change and highs mainly in the low-to-mid 50s. Confidence: Medium
SNOW POTENTIAL INDEX
A daily assessment of the potential for at least 1 inch of snow in the next week, on a 0-10 scale.
3/10 (→): Odds of even an inch are pretty low, even in our northern suburbs.
Updates we posted this morning:
7:30 a.m. update: Precipitation is starting to taper off and move away from the region. Radar still shows some narrow bands of (non-accumulating) snow and rain cycling through but those should move off or break apart over the next hour.
The main story for the rest of the day will be the wind and cold. Temperatures hold in the 30s and winds gust over 30 mph at times. Yes, we could see a few flurries or snow showers pop up that briefly limit visibility…and we’ll be watching for those.
Scroll down for the forecast through the weekend.
6:35 a.m. update: The back edge of the precipitation has reached western Fairfax and western Montgomery County. We are seeing the rain mix with and change to snow north and west of the Beltway and even a report of a coating on the grass around Damascus and Mt. Airy. But, aside from our far northern suburbs, any snow should melt on contact and be very short-lived. We’re still expecting precipitation to taper off over the next hour or so from west to east.
5:30 a.m. update: The snow is a bust – mostly. Winter weather advisories have been dropped for our far northern and northwest suburbs (upper Montgomery, Loudoun and Howard counties) as significant accumulating snow is no longer anticipated. The precipitation is exiting before the cold air has time to arrive for meaningful snow in a lot of the region.
Having said that, rain has changed to snow around Frederick, Md and the rain-snow line should press southeast over the next hour towards the northern side of the Beltway. The rain may end very briefly as sleet and/or snow into the Beltway, but radar and short-term models suggest the precipitation should end quickly between 7 a.m. and 8 a.m. in most spots. Our northern suburbs may get a quick grassy coating and see visibility reduced for a short time after the changeover to snow occurs, but impacts on the morning commute will be pretty limited.
