FORECAST IN DETAIL

Snow showers mess with our midday and afternoon — perhaps long enough to also affect the evening commute home. Even if the snow ends by the commute, there’s a chance its effects will linger. We’ll watch this sneaky snow chance for you throughout the day, so stay tuned! After it passes, a slow but steady warming trend arrives this weekend. Ready to thaw a bit?

Today (Friday): As clouds take hold, snow-shower potential enters the picture with time. It seems likely that at least snow showers break out by later morning, and it could end up being a fairly solid shield of mostly light but sometimes moderate snow. This doesn’t look like a huge amount of snow, but it could certainly be enough to cause some travel troubles, even during the day, thanks to cold temperatures. Upwards of one inch or a little more seems possible in the most consistent areas of snow, with many spots getting less than that and some out west seeing very little at all. With only light southeasterly breezes, high temperatures in the near 30 to mid-30s range, and near or below freezing in snow, should not feel much colder or more painful than previous days! Confidence: Medium

Tonight: Any last snow showers should wrap up quickly in the evening. Skies slowly clear. Breezes from the west-southwest may blow between 5-10 mph but nothing too biting. This warmer wind direction heralds the slow but steady warming trend that is set to begin this weekend, just be patient! Low temperatures look to be in the 20s regionwide, with near 30 possible downtown and other warm spots. Confidence: Medium-High

Tomorrow (Saturday): Somewhat tranquil weather kicks off our warming trend. Sunny skies are coupled with southwesterly (warm direction!) breezes around 10 mph, and mainly sunny skies! Everyone should get a good thaw, assuming you want one. High temperatures top out in the mid-to-upper 40s. Confidence: Medium-High

Tomorrow night: Downtown may halt falling below the mid-30s for pre-dawn low temperatures, with upper 20s still possible outside of the Beltway. It’s clear but there’s still a slight breeze—potentially variable in direction through the night — stirring things up just enough to prevent all the surface’s heat from escaping. We just can’t cool effectively and quickly with a slight breeze, even with clear skies appearing likely! Let us know if you need a more detailed explanation. Confidence: Medium-High

A LOOK AHEAD

Sunday: Clouds slowly increase, as do temperatures a bit more. We may see upper 40s to low 50s for early afternoon high temperatures, before clouds really move in and stop our climb. We have a slight tongue of moisture coming up from the Gulf of Mexico, which shouldn’t trigger daytime showers as it appears now, but may help relieve chapped lips for a bit! Confidence: Medium

Sunday night: Exact timing is hard to pin down, but a few light rain showers are possible — especially later into the evening. Regardless, clouds hang tough and dominate the sky. Low temperatures may hover near 40 downtown, with a few colder spots outside of the Beltway managing to dip into the mid-30s perhaps. Confidence: Low-Medium

Our warming trend tops out on Monday and Tuesday, with high temperatures into the 50s if not eyeing the low 60s. Clouds like likely at times, ahead of our next cold front, so it may not be the most beautiful start to our workweek. We’ll keep you posted on rain shower chances, which may erupt here and there, especially by Tuesday. Check back this weekend for tweaks to the forecast as we get closer! Confidence: Low-Medium

SNOW POTENTIAL INDEX
A daily assessment of the potential for at least one inch of snow in the next week, on a 0-10 scale.

4/10 (↑): Snow showers break out midday Friday. It all lasts a few hours. Best shot of one inch is east and northeast of our local area, and it’s no guarantee.
