A large high pressure area over the Northeast maintains dry weather in the region. As the high pressure area drifts offshore, south winds will promote warming. Farther west, a flow from the Gulf of Mexico sweeps north toward the Great Lakes, and we see showers and thunderstorms developing. In this video, we show how the rain should eventually spread east as a cold front moves slowly from the Midwest toward the East Coast.
Once the cold front arrives in or near the I-95 corridor, many possibilities open up. Two of them are shown on these maps. Last night's GFS showed a low pressure area from then the Gulf states latching on to the front to bring rain to the Middle Atlantic states Monday. The European model shows the same storm but has it moving more slowly and expanding its influence farther north and west. This map shows those two solutions. I expect more changes on both models during the next few days.
