D.C. area forecast: A calm Monday, big winter storm possible Wednesday, weekend warm-up Posted at 05:00 AM ET, 03/04/2013 Today: Mostly sunny. Chilly temps and brisk winds, but finally some legit sunshine. SPI: 7+ (↑).- At least some snow likely from Wednesday's Snowquester, and potential for significant amounts. The week get off to bright but chilly start before conditions begin to deteriorate late Tuesday. On Wednesday, a major winter storm - named Snowquester - impacts the region with possible periods of heavy snow (mixed with rain perhaps in milder locations). We clear out Thursday and, by the weekend, Snowquester is a distant memory with temperatures into the 50s. Today (Monday): A sunny day, but one that feels more like early February than early March. Despite the ample sunshine, highs only reach 40-45. Winds are from the northwest at around 10-20 mph with some higher gusts. It will feel more like the 30s this afternoon. Tonight: Clear and cold, with lows in the low-to-mid 20s in the colder suburbs to near 30 downtown. Winds from the northwest are light, around 5-10 mph. Tomorrow (Tuesday): High clouds increase in the morning and the cloud cover lowers and thickens in the afternoon. There's an outside chance of a little light rain before dark. Highs range from 40-45. Winds are light. Confidence: Mediium-High Tomorrow night: Rain and snow are likely to develop, especially after midnight. Rain or a rain/snow mix is likely to change to snow before dawn along and west of I-95. Lows range from 30-34 (suburbs-city). Snow is likely Wednesday, except rain or snow mainly east of I-95. The snow could be heavy at times. But if the storm tracks too far south, lighter precipitation would be expected, and more rain may mix with the snow, even west of I-95. Highs should range from 32-36 (western suburbs-city) Snow and/or rain tapers off Wednesday night, with lows 30-34 (suburbs-city). Here are our current snowfall odds: Chance of 2" or more: 70-80 percent Chance of 5" or more: 45-60 percent Chance of 10" or more: 10-30 percent Note: The low end of the ranges apply to D.C./I-95 and points east, while the higher end of the ranges apply to areas west of D.C. and I-95 (where the accumulation potential is greater due to colder temperatures). Thursday and Friday at least partially clear out behind the storm, but they are breezy and remain colder than normal. Thursday is the windier and colder of the two days, with highs 35-40, while Friday's highs reach the mid-40s or so. Overnight lows are in the 20s to near 30. Temperatures moderate for the weekend, with highs near 50 Saturday under partly sunny skies. By Sunday, highs may climb into the mid-50s, while clouds increase. There's a slight chance of a rain shower by Sunday evening. Overnight lows Saturday range from 33-40 (suburbs-city) Confidence: Medium
