FORECAST IN DETAIL

Temperature Map

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

One day at a time we emerge from this latest bout with brutal cold, not to mention last night’s dusting (north/west) to around 2″ (south/east) of powdery snow for much of the area, and as much as 2-4″ in Southern Maryland where travel requires caution this morning. Today’s improvement is minor but noticeable, with highs in the 20s several degrees warmer than yesterday, but still with biting wind chills. Tomorrow we manage the 30s, and Friday we more fully defrost with highs in the 40s. Highs in the 40s should stick around through the weekend, but with enough cold air above the surface to threaten a bit of mixed precipitation.

Today (Wednesday): Watch out for slick roads early this morning, and wind chills only slightly better than yesterday, in the single digits to near zero. Skies turn mostly sunny this morning and stay that way through the day, helping temperatures rise from near 10 to the mid-teens this morning, to the mid-20s for afternoon highs. Even then, though, breezes from the northwest around 10-15 mph keep wind chills in the teens. Confidence: High

Tonight: Winds become light and temperatures tumble once again under clear skies. Lows settle mainly in the teens, perhaps dipping into the single digits in the outer north and west suburbs. Confidence: High

Tomorrow (Thursday): High pressure looks to hang around long enough for a mostly sunny and overall pleasant Thursday, at least relative to recent days. Highs hit the mid-30s with light winds. Confidence: High

Snow Potential Index

A daily assessment of the potential for at least ~1″ of snow in the next week, on a 0-10 scale.

2 (↓): Any weekend flakes shouldn’t amount to much. Maybe something brewing next Tues-Wed, but that’s a ways out.

Tomorrow night: As high pressure shifts off the coast, clouds increase and temperatures continue their moderating trend with lows in the 20s. Confidence: High

A LOOK AHEAD

Friday presents a 30% chance of a passing rain or snow shower. Otherwise, we’re  partly to mostly cloudy and warmer still, with highs “roaring” into the 40s. Friday night trends partly cloudy with lows in the upper 20s to mid-30s. Confidence: Medium-High

On Saturday, the front end of our next system approaches. While much of its precipitation may pass to our north, enough may run into lingering cold air overhead to produce some light mixed precipitation as highs reach the 40s. Any precipitation Saturday night is likely to be light and in the form of rain, with lows probably no lower than the mid-to-upper 30s. The cold front portion of the system comes through Sunday with a decent chance of showers at some point, perhaps ending with some conversational snowflakes, and highs again in the 40s. Confidence: Low-Medium
