Gulf States Face Up to 3.99 Inches of Rainfall Over the Next 7 Days as Hot Ridge Builds Into the Plains and Coastal Storm Possible by Mid-Month
GULF STATES — Some of the best rainfall totals over the next 10 days are concentrated across the Gulf Coast states, where they are needed most, with the NOAA Blend of Models showing accumulations of up to 3.99 inches through Friday May 15, 2026. Meanwhile a hot ridge building over the Southwest into the Plains is expected to push east by mid-month, and a small coastal storm may develop along the East Coast.
Where the Heaviest Rain Falls Over the Next 7 Days
The NOAA Blend of Models precipitation forecast valid from 06Z May 8 through 06Z May 15, 2026 shows the heaviest rainfall totals concentrated across the Gulf Coast corridor, with the highest amounts focused across Louisiana, Mississippi, Alabama, and the Florida Panhandle.
| Region | Forecast Rainfall Total |
|---|---|
| Gulf Coast core — Louisiana, Mississippi | 1.5 to 3.99 inches |
| Alabama, Florida Panhandle | 1.0 to 1.9 inches |
| Texas Gulf Coast | 0.6 to 1.6 inches |
| East Coast corridor | 0.5 to 1.3 inches |
| Central and Northern Plains | 0.1 to 0.4 inches |
| West and Southwest | Near zero to 0.1 inches |
The maximum forecast total across the entire map reaches 3.99 inches across the Gulf Coast bullseye zone.
The East Stays Cool and Unsettled
Across the Eastern United States, the pattern through mid-May remains cool and unsettled with no major storm systems expected. Conditions will feature general spring showers and thunderstorms rather than any organized severe weather outbreak for the region during this period.
Hot Ridge Builds Into the Plains by Mid-Month
A hot ridge currently positioned over the Southwest is expected to build eastward into the Plains and potentially further east by mid-month. This ridge will bring significantly warmer and drier conditions to the central United States as the pattern transitions away from the current cool and unsettled setup across the East.
Coastal Storm Possible Along the East Coast
Forecasters are watching for the potential for a small coastal storm to develop along the East Coast during this period. The strength and track of any such system will depend on the evolution of the trough pattern currently locked over the Eastern United States.
The Bottom Line for the Next 10 Days
The best weather story over the next 10 days belongs to the Gulf States, where meaningful rainfall totals of 1.5 to nearly 4 inches are forecast across Louisiana, Mississippi, and Alabama. The rest of the country sees a split between a cool and unsettled East, a building heat ridge across the Southwest and Plains, and a dry West.
