11:30 a.m. update: We’ve already seen a few snow flurries in parts of the region and there is still a risk of snow showers or squalls this afternoon. Snow could be mixed with rain and sleet, through early this afternoon.

Temperatures are above freezing (falling through the 40s into the 30s this afternoon), so roads should remain just wet (except a little slush could build-up in heavy bursts), but any snow could reduce visibility. In addition, winds may gust over 30 mph at times.


HRRR model shows scattered snow showers zipping through the region this afternoon - especially west and northwest of Washington.

8:55 a.m. update: Some of the higher resolution modeling is bringing a few snow showers or snow squalls into the area midday through afternoon or so. These are aided by lake effect snow to some degree and may blow in on the gusty northwest winds. Keep an eye out!

FORECAST IN DETAIL

Winter is here. You’ll notice much colder air today as well as some strong winds pushing it into our area. This sets the stage for what could be our first snow event across the local area since November, given that the December storm only clipped our southern suburbs. There’s still some uncertainty there, though, and it may be that places south are favored once again.

Tomorrow (Thursday): It remains mostly sunny on Thursday, and it’s also cold and blustery. Afternoon highs will reach only the upper 30s and there are winds from the northwest at 10-20 mph with higher gusts. Wind-chill values will make it feel more like temperatures are in the upper 20s for much of the day. Confidence: Medium-High

Tomorrow night: Mostly clear, cold and breezy. Temperatures will fall well below freezing in all locations, with lows in the mid-20s or so. Northwest winds at 10-20+ mph create wind-chill values in the teens overnight. Confidence: Medium

A LOOK AHEAD

Gusty winds finally back off by Friday, leaving us with mostly sunny skies but cold conditions. Daytime highs reach only the mid-to-upper 30s. Clouds start to overspread the region Friday night, keeping temperatures from falling off too much. Overnight lows are in the mid-or-upper 20s. Confidence: Medium

Saturday and Sunday will bear some close watching, as a low pressure system developing over the southeastern United States makes a close pass to our region. We’re not expecting any real issues on Saturday, with mostly cloudy skies and temperatures in the mid-30s in most spots. Light to moderate snow may develop overnight on Saturday and continue into Sunday morning. It’s too early to give any totals, but the potential exists for up to several inches. Confidence: Low

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.

5/10 (↑) Measurable snow seems a decent bet this weekend, although the best odds remain south for now. It’s most likely to occur Saturday night and into Sunday.
