Hurricane Willa, once a Category 5 storm that made landfall on the western Mexican coast Tuesday, will aid in heavy rains late-week across parts of the southern Plains, Gulf Coast, and Southeast as a new area of low pressure develops across the region. Then by the weekend, that low will evolve into a nor’easter that will move up the East Coast, bringing some snow to the interior Northeast.

This afternoon, low pressure is beginning to organize near the Texas coastline. As the deepening pressures along with the rich, tropical moisture associated with Willa move east, so will the rain. This Wednesday, rain will be widespread in light to moderate quantities across the southern Plains and up through the southern to central Rocky Mountains. The heaviest of rain — if any — will be found near the coast of Texas thanks to the Gulf of Mexico being right there, an area with abundant moisture. Beginning late in the day, we’ll see a warm front lift through the central Gulf Coast, which will usher in a line of heavy rain and thunderstorms to the region. That will persist into the overnight hours, especially across southern Louisiana.

On Thursday, everything will move to the east. The surface low pressure will provide rain and thunderstorms to the Gulf Coast state and Southeast during the day while an upper-level low associated with a digging trough of low pressure will bring rains to the central Plains, Midwest, and Mid-South. The best risk for any flash flooding or heavy rain will once again be located near the Gulf. By the end of the day, the precipitation will span as Far East as South Carolina and as far south as northern Florida.

Finally by Friday, the low pressure will begin to take a turn to the north as it nears the coast. This will allow for a widespread light to moderate rain to much of the Midwest and Mid-Atlantic while it clears out across the Southeast by midday, although it may be slower to exit in the Carolinas.

Drier and cooler air will then move in behind the low thanks to the cold front tracking south and east. This will be quite the powerful front, bringing the dry air as far south as the Florida Keys.

Through Friday, a widespread 0.5 to 1.5 inches of rain can be expected with localized totals of up to 3 inches near the Gulf Coast, which may trigger minor flooding.
