Discussion
Low pressure will slide through the eastern Great Lakes region today and a strong cold front will trail on its southern side all the way into the southern states. Spotty and light mixed precipitation may break out this morning and mid-day, but the steadier and heavier stuff comes later this afternoon as the cold front arrives. Precipitation should change to snow later today and untreated roads could get slick by the evening commute. Likely snow accumulations later today/early tonight in the DC metro region should be on the order of a coating to a couple of inches. A true Arctic frontal boundary arrives on Wednesday and it is likely to be accompanied by strong wind gusts, possible snow showers, and perhaps even a heavier snow squall. The best chance for any snow on Wednesday should come between the hours of 10AM and 4PM. Arctic air then blasts into the Mid-Atlantic region late Wednesday and temperatures should be in the single digits by early Thursday morning.
