TODAY’S DAILY DIGIT
A somewhat subjective rating of the day’s weather, on a scale of 0 to 10.
4/10: Gotta bump it up as we finally get some sun. But it’s still a chilly, breezy day in the end.
Today: Finally some sun! Breezy. Highs: Low-to-mid 40s.
Tonight: Mostly clear and cool. Lows: Mid-20s to near 30.
Tomorrow: Increasing clouds. Highs: Upper 30s to near 40.
FORECAST IN DETAIL
Well, we can see more clearly now that the rain is gone, but it leaves a couple obstacles in our way in the form of cold and wind, even if today is a bright, bright, sunshiny day. A blustery breeze ushers in colder air today before clouds increase again tomorrow. Rain chances return tomorrow night into Tuesday, with a wintry mix possible for D.C.’s far north and west suburbs, as a coastal storm threatens conditions ranging from scattered showers to a decent dousing depending on its exact track.
Today (Sunday): Don’t adjust your eyes, yes, that’s the sun you’re seeing out there! We’ve finally broken out of the damp and dreary, but it costs us a few degrees in the process. The wind doesn’t help much either, with a breeze from the north at 15-25 mph for much of the day, though it may peak early, and gusts near 30 mph. Those winds make temperatures struggling through the 30s toward highs in the low-to-mid 40s feel more like the 30s all day long, even with mostly sunny skies. Confidence: High
Tonight: Skies stay mostly clear overnight, and despite slackening some, a steady breeze continues from the north through the night. Temperatures drop through the 3os to lows in the mid-20s to near 30. Confidence: High

Tomorrow (Monday): “The wedge” returns tomorrow, with high pressure over the Northeast and developing low pressure off the Southeast coast trapping cold air east of the mountains. Clouds are on the increase as skies trend toward mostly cloudy through the day. Winds from the north-northeast are lighter than today, around 10 mph, but still add a bit of a chill to already chilly highs in the upper 30s to near 40. Confidence: Medium-High
Tomorrow night: A few showers may develop during the evening, with a better chance of more numerous showers overnight. Can’t rule out a bit of conversational sleet or snow mixing in locally. Areas further north and west of the District — from Carroll, Frederick, Loudoun, and Fauquier counties toward points north and west — may see an accumulating wintry mix. Overnight lows drop into the low-to-mid 30s. Confidence: Medium
A LOOK AHEAD
That risk of a wintry mix may linger into early Tuesday morning for our northern and western suburbs — with again any accumulation likely confined to Carroll, Frederick, Loudoun, and Fauquier counties and points north and west — before changing to plain rain. Models still differ on the track and breadth of a coastal storm responsible for the precipitation. If it hugs close enough to the coast, which it looks like it might, then we’ll see a good chance of rain area-wide through much of the day. If it tracks a bit further off the coast, then rain might be less of a factor. Locked in by clouds, highs max out in the low-to-mid 40s. Shower chances diminish Tuesday night as the storm pulls off to the north, with a few snow flurries possible overnight as lows dip to the low-to-mid 30s for most. Confidence: Low
An upper-level area of low pressure moves by on Wednesday keeping our skies mostly cloudy. The instability created by a pocket of cold air aloft, and a relatively mild surface, could spawn a few scattered showers, and maybe even some graupel if we’re lucky. The overall chance of precipitation is around 30 percent. Expect highs in the low-to-mid 40s again. Confidence: Low-Medium
SNOW POTENTIAL INDEX
A daily assessment of the potential for at least ~1″ of snow in the next week, on a 0-10 scale.
1/10 (→): Far N/W burbs (Frederick and Loudoun counties) may see Monday night wintry mix, though 1 inch seems unlikely.
