Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1158 PM CST Thu Feb 10 2022
Valid 121200Z - 131200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Aside from parts of southern Florida, and perhaps parts of Deep
South Texas, the risk for thunderstorms appears negligible across
much of the U.S. Saturday through Saturday night.
...Synopsis...
Upper troughing is forecast to cover much of the CONUS early
Saturday, stretching from the Intermountain West to off the East
Coast. An embedded shortwave trough, initially extending from the
northern Plains southwestward into the southern High Plains, is
expected to progress eastward/southeastward throughout the day,
ending the period extended from the Upper OH Valley into the far
western Gulf of Mexico. Another shortwave trough is expected to
follow in the wake of the first, moving through the northern/central
Plains and Upper/Mid MS Valley late Saturday night and early Sunday
morning. This overall pattern evolution will help maintain broad
upper troughing across the central and eastern CONUS while upper
ridging initially centered off the west coast slowly builds
eastward.
At the surface, a cold front will likely extend from the Upper OH
Valley southwestward through the TN Valley, Mid-South, and central
TX early Saturday. This front is forecast to continue
southward/southeast through the period and is expected to have moved
through all of the central and eastern CONUS except for the southern
FL peninsula by early Sunday.
Modest low-level moisture will be in place across the TX Coastal
Plain as the front moves through, with frontal lift in the vicinity
of this moisture contributing to isolated thunderstorm potential.
Isolated thunderstorms are also possible across southern FL, mainly
early Sunday morning as the front approaches the region.
