FORECAST IN DETAIL

Temperature Map

Temperatures: Latest D.C. area temperature map. See interactive map on our Weather Wall.

It’s much colder than normal to start this week and we throw in yet another snow chance, Tuesday. The normal high is approaching 60 degrees and we’ll average 20 degrees below that through Wednesday. But the pattern changes Thursday through the weekend, with normal to even above normal temperatures arriving on the scene.

Today (Monday): Lots of sunshine today, but deceptively chilly. After a sub-freezing start, highs only recover into the low-to-mid 40s.  Winds are from the northwest at around 10 mph. ConfidenceMedium-High

Tonight: Mostly clear early on, followed by increased clouds.  There’s a 30 percent chance of light snow in the pre-dawn hours (4-7 a.m.), with lows ranging from near freezing downtown to the upper 20s in the colder suburbs. Light winds. Confidence: 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. More info

4/10 (↑) – Tuesday’s storm could lay down a quick inch or so, but not a major storm for DC.

Tomorrow (Tuesday): Snow is likely in the morning (70 percent chance), with more scattered snow showers in the afternoon…especially east of the city.  Temperatures at or below freezing to start the day may allow for some slushy accumulation on roadways, especially in our colder suburbs.  As the day wears on, any snow will be challenged to accumulate much, except on grassy areas.  Total accumulations are probably around 1″, but stay tuned for a more detailed update with a forecast map this afternoon.  Highs are mostly in the mid-to-upper 30s.  Confidence: Medium

Tomorrow night: Some evening snow showers are possible, especially east of town, with little or no accumulation.  Otherwise, skies gradually clear, but it’s extremely windy as our snow-maker turns into a powerhouse storm offshore. Lows are in the 20s to near 30 downtown.   Confidence: Medium

A LOOK AHEAD

A mostly sunny Wednesday, but blustery and cold.  Highs only reach the upper 30s to lower 40s, with a very strong wind from the north.  Winds start to diminish Wednesday night, with chilly lows in the 20s to near 30. Confidence: Medium-High

Thursday isn’t exactly a mild day, but it marks the start of a warming trend.  Under partly sunny skies, highs aim for 50-55.  Winds start to pick up a bit in the afternoon.  A little breezy Thursday night, with lows in the upper 30s in the colder suburbs to the mid-to-upper 40s downtown. Confidence: Medium

Friday’s mild, but a weak front passing through means mostly cloudy skies and a chance of showers.  Highs are near 60-65.  The shower chance lingers into Friday evening, but then skies partially clear overnight, with lows in the 40s. Confidence: Medium

The weekend looks pretty good at this point, with partly sunny skies and generally dry weather.  We’ll need to keep an eye on a possible backdoor cold front to the north that could bring some chillier conditions (highs only in the 40s to low 50s). But said front probably stays to our north.  The end result is a couple good-looking days, with highs around 60 both days. Confidence: Low-Medium
