A Winter Weather Advisory is in effect from 4 am until 1 pm on Tuesday for Montgomery, Howard, Carroll and Frederick Counties in MD and all points westward AND in Loudoun, Fairfax, Prince William, Fauquier, Stafford and Spotsylvania Counties and points westward in VA. The farther west you are of these areas, the greater likely impact of the wintry mix and longer the duration of the Advisory.
A Winter Storm continues to move along the Gulf Coast of LA and MS. It will make steady progress toward the southern Atlantic Coast. As it moves northward, adjacent the U.S. East Coast, tomorrow and Wednesday, a variety of weather conditions will rapidly develop and will have significant impacts on the eastern quarter of the country. Although the precipitation, in advance of the core of the storm, may begin as a wintry mix in areas west of the Chesapeake Bay, this will be by and large a rain storm…a significant rain storm, for most of the I-95 corridor all the way to New England.
The morning mix may be briefly more significant along and west of the Blue Ridge. The local wintry mix will change to rain before noon tomorrow and the rain may be heavy later tomorrow. Two inches of rain or more could fall in our area. And as the storm departs on Wednesday, the leftover rain may change to snow as colder air is pulled in on the back side of the system and it becomes quite WINDY. No significant accumulation is anticipated. HOWEVER, the farther west and northwest you go from Washington, there will be more significant impacts from sleet, freezing rain and snow. Thanksgiving will be sunny and cold!
