Day 3 Convective Outlook  
NWS Storm Prediction Center Norman OK
0131 AM CST Wed Feb 10 2021

Valid 121200Z - 131200Z


Organized severe thunderstorms are not forecast on Friday.


Strong surface high pressure and an arctic airmass will persist
across much of the CONUS east of the Rockies on Friday. A mostly
stationary front will reside from the Piedmont of SC west/southwest
through southern AL to the mouth of the MS River and then just
offshore the TX coast. This boundary will remain nearly stationary
as another upper shortwave trough pivots southeast from CA toward
the southern Rockies during the period. This will maintain a warm
advection regime across the southeastern U.S. A narrow warm sector
will reside across FL into southern GA/AL ahead of the stationary
boundary while isentropic ascent results in showers and isolated
elevated thunderstorms from the Upper Texas Coast toward the TN
Valley. While some warm-sector thunderstorms are possible, poor
lapse rates and weak instability will preclude severe potential.
