Short-term
A strong high pressure will remain over the eastern seaboard through Thursday. A weak ridge builds over the Northeast Wednesday into Friday. Dry air will be advected into the upper levels leading to mostly clear skies for the mid-Atlantic.
Long term
A deep upper level trough will dig into the eastern seaboard. Late Thursday, a cold front will move through the southeastern portions of the US bringing precipitation to areas south of the Mason Dixon Line. The northern mid-Atlantic region will remain relatively dry with some increase in cloud cover late Thursday into Friday. Over the weekend, a strong upper level ridge will build over the region, translating to a strong surface high pressure.
