D.C. area forecast: Cold today, really cold tomorrow; wintry mix this weekend?

Today’s Daily Digit

A somewhat subjective rating of the day’s weather, on a scale of 1 to 10.

5
The cold is so much less exciting without snow in the air. At least it’s not as frigid as Thursday will be.

Express Forecast

Today: Partly sunny and cold. Highs: Low-to-mid 30s.

Tonight: Partly cloudy. Lows: Upper teens to low 20s.

Tomorrow: Really cold, breezy. Highs: Mid-to-upper 20s.

FORECAST IN DETAIL

Those with snow on the ground will see more melting today thanks to some sun and highs near or a bit past freezing. Of course, that’s still pretty cold, but not so bad compared to tomorrow when temperatures may not get out of the 20s with wind chills in the teens. The cold moderates back into the 30s on Friday before our next chance of wintry weather threatens to disrupt the first half of the weekend.

Temperature Map

Today (Wednesday): Other than some morning slick spots after overnight lows in the teens to mid-20s, today starts much more calmly than yesterday. No precipitation to worry about, just partly sunny skies and chilly temperatures, headed for highs in the low-to-mid 30s this afternoon. Winds are light, around 5-10 mph from the west. Confidence: High

Tonight: Another chilly night awaits as lows dip mainly to the upper teens to low 20s under partly cloudy skies. That means any puddles left by the daytime warming will re-freeze overnight. Also overnight, breezes pick up from the northwest as a reinforcing cold front comes through. Confidence: High

Tomorrow (Thursday): Behind the overnight cold front, daytime winds from the northwest continue to bring in colder and drier air. The result is an even colder day than today, with highs probably only in the mid-to-upper 20s, and wind chills in the teens thanks to 10-20 mph winds. Skies should be partly to mostly sunny, but when it’s this cold that won’t make much of a difference. Confidence: High

Snow Potential Index

A daily assessment of the potential for *accumulating* snow for the next week on a 1-10 scale.

3 (↓) Saturday storm looks more like a mixed precip event, but could start with some white stuff.

Tomorrow night: Winds die down and, even with some clouds floating by, most suburbs should drop down to the teens for lows. Perhaps downtown holds near 20. Confidence: High

A LOOK AHEAD

It’s still cold, but temperatures do make a decent recovery on Friday, rebounding to highs in the 30s with light winds and partly to mostly sunny skies. Friday night lows fall back to the mid-20s to low 30s, with a chance of mixed precipitation by morning. Confidence: Medium

Mixed precipitation seems increasingly likely to arrive sometime Saturday with highs in the 30s to near 40, possibly changing to all rain before the storm moves out Saturday night. We’ll fine-tune this forecast as we get later in the week. Any lingering precipitation should exit fairly early on Sunday, with highs right now aiming for around 40. Confidence: Low
