...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms will be possible on Tuesday from far
southeast Georgia to the Florida Peninsula. No severe threat is
forecast.
...DISCUSSION...
West-northwesterly mid-level flow will remain in place on Tuesday
across much of the nation. At the surface, a cold front is forecast
to advance southward to near the central Gulf Coast and northern
Florida. As surface heating and low-level convergence increase near
the front, isolated thunderstorm development will be possible. No
severe threat is expected over the continental U.S. on Tuesday and
Tuesday night.

0340 AM CDT Sun Mar 22 2026
Valid 251200Z - 301200Z
...DISCUSSION...
...Wednesday/Day 4 to Thursday/Day 5...
An upper-level ridge will move into the Rockies on Wednesday, as
northwesterly mid-level flow remains from the Great Plains to the
eastern U.S. On Thursday, the ridge will become less amplified as it
moves into the Great Plains. At the surface, low-level moisture is
forecast to return northward into the lower to mid Mississippi
Valley. Within this moist airmass, a pocket of moderate instability
is expected by late Thursday afternoon. Thunderstorm development
will be possible near a front along the northern edge of the
stronger instability from northeast Missouri east-northeastward into
north-central Ohio. Storms are expected to move east-southeastward
across the Ohio Valley on Thursday afternoon and evening. A severe
threat will be possible, but the magnitude of any potential threat
is still uncertain.
...Friday/Day 6 and Sunday/Day 8...
From Friday into Saturday, a cold front is forecast to move
southward from the mid Mississippi Valley to the central Gulf Coast.
Isolated thunderstorms will be possible along parts of the front
both Friday and Saturday afternoon. Weak instability should keep any
severe threat marginal.
On Sunday, the models are forecasting a dry airmass over most of the
continental U.S., suggesting the potential for storms is low.
