Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1145 PM CST Wed Feb 02 2022
Valid 041200Z - 051200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected on Friday.
...Synopsis...
The upper trough extending from the Upper Midwest to the Mid-MS
Valley and southern Plains will shift eastward on Friday, becoming
positioned from NY/PA to the coastal Carolinas by Saturday morning.
The southern branch of the trough will shift east more slowly,
tracking from the southern Plains toward the Lower MS Valley. Strong
southwesterly deep-layer flow associated with this system will
overspread much of the Southeast U.S. northward through New England.
At the surface, a strong cold front will extend from the Chesapeake
Bay vicinity to the western FL Panhandle and the central Gulf of
Mexico. Isolated thunderstorms are possible ahead of the front
across parts of the Southeast into the NC/SC Piedmont/coastal plain.
South/southwesterly low-level winds will transport 60s dewpoints
northward into the Carolinas. While weak to moderate vertical shear
will be in place given increasing wind speeds with height, poor
lapse rates and limited diurnal heating will preclude stronger
destabilization across the Southeast. Low-level flow will remain
veered ahead of the front in the absence of stronger surface
cyclogenesis. Furthermore, large-scale ascent will remain somewhat
nebulous, especially across FL/GA. As a result of poor
thermodynamics and weak forcing for ascent will limit warm sector
convection, with any thunderstorms tied more closely to the cold
front. Given boundary-parallel deep-layer flow, any storms that
develop will become undercut by the cold front and severe potential
will remain low.
