D.C. area forecast: Brief mix to rain today, blustery Wednesday; next storm by late Friday

9:15 a.m. update: A band of mixed precipitation - rain, sleet and snow - is moving through the metro region. It has reached areas west of the District and should move into the eastern suburbs before 10 a.m. The heaviest precipitation is north and northwest of D.C., and more in the form of sleet and snow. With temperatures above freezing, significant issues on the roads are not expected, but briefly reduced visibilities and a slick spot or two are possible in heavier bursts. As we head into the afternoon, mixed precipitation should change to rain with temperatures rising into the 40s.

FORECAST IN DETAIL


In what has become an all too predictable routine this winter, we warm up just enough today to get rain (rather than snow - except for a possible brief mix at the onset) before we turn colder and drier. Below average temps dominate Wednesday to Thursday before a new storm approaches late Friday. There is a chance enough cold air holds for mixed precipitation Friday night before changing to rain which lingers into Saturday. Drier weather returns for Sunday.

Today (Tuesday): Cloudy with rain developing mid-to-late morning and ending by mid-to-late afternoon. Some mixed precipitation is possible in the far north and west suburbs, especially in the late morning. A winter weather advisory is in effect for the mountains well to our west. Highs range from the mid-to-upper 40s. Winds from the south and southwest at 10-15 mph. Confidence: Medium

Tonight: Partial clearing and turning colder with temperatures dropping into the mid-to-upper 20s or probably right near 30 in the city. There could be a few slick spots *well* north and west of D.C. Breezes from the west and northwest at 10-15 mph. Confidence: High

Tomorrow (Wednesday): Morning sunshine could give way to instability cloud cover by late morning and afternoon with cold winds blasting us from the west and northwest at 15-20 mph (gusts as high as 30-35 mph). Highs range from the upper 30s to the low 40s, but those annoying winds offer a much colder perception. Confidence: High

Tomorrow night: Winds begin to die down somewhat overnight as we find partly cloudy skies and temperatures dropping down into the low-to-mid 20s. Confidence: High

A LOOK AHEAD

Thursday should be a touch warmer with more sunshine and less windy weather overall. Highs range through the low-to-mid 40s with breezes closer to 5-10 mph most of the time. Thursday night is partly cloudy with lows in the mid-to-upper 20s. Confidence: Medium

Friday brings the arrival of our next weather system. The guidance has been trending slower with this feature such that the precipitation might not commence until very late afternoon or evening now. By that point, we should be warm enough for just plain rain yet again, but high pressure stalled over New England could offer some mischief by locking in some colder air Friday evening. For now, let’s go with low-to-mid 40s for highs along with cloudy skies and a 30% chance of rain showers toward evening (rain could be mixed with sleet or snow in the far north or west). Friday night sees more rain with a slight risk of mixed precipitation and lows in the 30s. Confidence: Low

The weekend isn’t looking as nice now as rain showers could linger into Saturday along with cloudy skies and temperatures stuck in the 40s. Some clearing is seen returning by late Saturday into Saturday night when lows dip into the 30s again. Sunday aims for partly sunny skies and maybe the warmest day of our forecast period with upper 40s to low 50s forecast. Confidence: Low
