The final storm of this streak, which brought flooding rains to portions of the middle of the country, will finally move toward the East Coast and eventually out of the United States Sunday night, and its associated cold front will clear its precipitation with it.

This Sunday, the rain will have cleared out of the flood-ravaged areas of the ArkLaTex, Mid-Mississippi Valley, much of the Ohio Valley, and Great Lakes region thanks to the cold front and drier air behind it. To the east of there, however, rain and even thunderstorms will continue. Much of the Northeast and Mid-Atlantic will deal with periods of rain through much of the day as the rain clears out west to east. Snow, freezing rain, and sleet are possible in the higher elevations of northern New England due to colder air intruding from Canada. To the south, we’ll be watching training rain and thunderstorms across the Gulf Coast states from coastal Texas through inland Louisiana, Mississippi, Alabama, Georgia, and the western Carolinas. There is the chance for a few isolated severe thunderstorms as well along the Gulf Coast. These training storms may lead to flash flooding as well, especially from southeastern Texas through northern Georgia.

Then overnight Sunday, all of the precipitation will clear out of the Northeast and northern Mid-Atlantic region by midnight while the Southeast and Gulf Coast remains wet as a new area of low pressure rides the front boundary from the Gulf of Mexico. This will keep the rain around for another day in this region. During the overnight hours, rain and thunderstorms will continue from southeastern Texas through the interior of the Gulf Coast states and into the southern Appalachians. The rain showers will reach as far north as the tidewater of Virginia.

NAM Future Radar at 8am ET Monday

On Monday, we’ll still be talking about the rain. There may be a line of sub-severe storms that develops from the coast of Louisiana through Northern Georgia. This would be ahead of the eastward-moving cold front. In the morning on Monday, showers and thunderstorms are forecast from southern Louisiana through the southern Appalachians and into the Carolinas. A few showers may sneak into portions of Virginia and the DelMarVa as well. Then in the afternoon, the rain will finally come to an end in most of Louisiana and inland Mississippi and Alabama. The thunderstorms will continue along the coast east of New Orleans as well as into portions of Georgia and the Carolinas. By the evening, this line of showers and thunderstorms will weaken considerably and the activity will become scattered before all of the precipitation diminishes and moves off the Southeast coast early Tuesday morning.
