Most of the forecast models indicate that a period of wintry precipitation will fall during the overnight hours on Thursday with precipitation ending just before the morning rush hour. Due to the precipitation falling during the overnight hours, snow will stick to untreated surfaces with slick spots likely by morning, especially away from the Urban Heat Island of downtown Washington.
If you’re ready for Spring, be patient, the medium-range forecast models indicate that unseasonably cold weather will return to a large portion of the United States as we head into the first full week of March.
The image above, (courtesy weathermodels.com) shows the 5-day ensemble mean of temperature anomalies the first ten days of March and it is looking rather cold across a large portion of the Midwest into the Mid-Atlantic.
A powerful cold front will cross the Washington Region this afternoon ushering in gusty winds in its wake. Winds could occasionally gust over 55 MPH in locations across the higher elevations of the Potomac Highlands, Catoctins, Blue Ridge and near/across the Chesapeake Bay.
The image above (courtesy weathermodels.com) from the North American Model (NAM) shows potential peak wind gusts from 7pm Sunday through 5pm Monday. The gusty winds coupled with saturated soil from the recent soaking rain increase the risk of downed trees.
