Discussion

A major storm will ride up the eastern seaboard over the next 24 hours and it will bring the I-95 corridor region from DC to New York City heavy rainfall that may end up in the 2-4 inch range by midday tomorrow as we go from drought-like conditions to flood-like in quite a hurry. There may be enough cold air around early this morning to allow for a brief period of sleet, snow and/or freezing rain at the onset of the precipitation event to the west and north of the District, but plain rain is likely by this afternoon as slightly milder air pushes in and it will become heavy at times. Heavy rainfall will continue tonight up and down the I-95 corridor and there can be a few thunderstorms mixed in. Winds will increase noticeably tonight out of the south or southeast pumping in even milder air and temperatures will likely rise into the 40's by early Wednesday. As the storm pulls away later tomorrow, another batch of Arctic air will move into the Mid-Atlantic region, temperatures will drop quickly, and lingering rain showers could change to snow showers accompanied by strong northwest winds. Thanksgiving Day promises to be very cold with well below normal temperatures for this time of year and strong northwest winds in the morning hours; however, the winds are likely to slacken off during the afternoon and evening as high pressure edges overhead.
