Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
1104 PM CST Mon Feb 08 2021

Valid 091200Z - 101200Z


Severe thunderstorms are not forecast through tonight across the
contiguous United States.

In the midlevels, a mean trough over the Midwest will continue to
deamplify during the morning with quasi-zonal flow extending from
the central Great Plains east to the Atlantic coast.  A minor
perturbation over the northwest Gulf Coast at daybreak will move
east along the northern Gulf Coast and weaken during the day.  A
zone of low-level warm air advection over the northeastern Gulf
Coast during the morning will concurrently weaken during the day. 
Elevated weak instability will contribute to a focused area of
scattered thunderstorms during the morning over the northeast Gulf
Coast.  Ample effective shear (50 kt) could lead to a locally strong
storm with small hail.  The shower and thunderstorm activity will
likely lessen in coverage by early afternoon as it shifts generally
east of I-75 in southern GA/north FL.
