Maryland–D.C. – The air feels mild and calm now, but wet pavement could turn slushy fast by Sunday night as colder air slides into the capital. A developing coastal system is lining up to bring accumulating snow into Washington by early Monday, threatening the morning drive.
According to the National Weather Service, rain develops Sunday with highs near 38 degrees, then changes to snow Sunday night after 10 p.m. New snow accumulation of 2 to 4 inches is possible before midday Monday. Northwest winds could gust as high as 26 to 29 mph, especially by Monday afternoon.
Reagan National Airport sits near 47 degrees late this morning with partial clearing. Temperatures fall into the mid-30s tonight. Little or no accumulation is expected before dawn Sunday, but conditions shift steadily through the day. By late evening Sunday, steadier snow may coat bridges and untreated roads first. Plan ahead if you rely on I-395, I-295 or the Capital Beltway.
Snow may linger into early Monday before tapering. Highs reach near 39, which could create slushy conditions during the day. As skies partially clear Monday night and lows drop into the mid-20s, watch for flash freezing. Melted snow may refreeze, leading to slick sidewalks and black ice for the Tuesday commute.
Sunshine returns Tuesday with highs near 37. Temperatures rebound into the upper 40s by Wednesday, and milder air builds late week. Longer-range trends suggest above-normal readings into early March, hinting at early spring warmth after this February snow threat.
