Tough one to score. Kind of fun if we see first flakes of season. But the cold wind and rain part is no fun at all. Get the Digit on Twitter| Discuss on Facebook

FORECAST IN DETAIL


Don’t think anyone voted for this weather. It’s cold and windy today, and the culprit is a Nor’easter trying to clip us with some rain, likely mixed with snow. Some areas could even see a light accumulation if the snow falls heavy enough for a time. Cold winds linger tomorrow, but marked improvement arrives Friday, and the weekend is looking quite nice!

Today (Wednesday): A strengthening area of low pressure centered offshore tracks northward parallel to the mid-Atlantic coast. The D.C. area will be toward the western edge of the storm’s precipitation shield. That means a cloudy chill with a 60% chance of light to moderate rain, likely mixed with snow. It’s possible during the afternoon or evening we see a period of snow heavy enough for a slushy accumulation up to around 1”. Odds of accumulating snow range from about 20% south, southwest and west of the Beltway; to 30% inside the Beltway; to 40% north, northeast and east of the Beltway; to 50% as you head toward Baltimore (closer to where the storm will be getting stronger). Temperatures are mainly steady in the mid-30s to near 40, and breezes are brisk from the north/northwest at 10-20 mph. Confidence: Medium

Tonight: We hold on to a 60% chance of light to moderate rain or snow during the evening, again with odds of accumulating snow ranging from 20-50% as described above. Any precipitation should come to an end by late evening or overnight. A continued breeze helps keep temperatures from plummeting, so lows should be mainly in the low-to-mid 30s. Confidence: Low-Medium

Tomorrow (Thursday): Not impossible that suburban areas, where early-morning temperatures will be near freezing, see some slick spots for the early part of the morning commute. Otherwise, get ready for another cold and windy day. Partly sunny skies warm us a bit from today, to highs in the upper 40s to near 50, but winds at 15-25 mph from the northwest keep things feeling mighty chilly. Confidence: Medium-High

Tomorrow night: Winds should decrease, but we’ll keep enough of a breeze to prevent temperatures from going as low as they could. Lows bottom in the upper 20s to mid-30s (suburbs to city) under mostly clear skies. Confidence: Medium-High

A LOOK AHEAD

Come Friday, winds are down to a more polite 10-15 mph as temperatures climb higher. Partly to mostly sunny skies courtesy a large bubble of high pressure help highs reach the low-to-mid 50s. Mostly clear Friday night with lows in the 30s (suburbs) to near 40 (downtown). Confidence: Medium-High

What a wonderful weekend treat! High pressure hangs around and gives us a partly to mostly sunny Saturday and Sunday with highs near 60, and Saturday night lows from the upper 30s to mid-40s. Confidence: Medium
