SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0131 AM CST Wed Feb 10 2021 Valid 121200Z - 131200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Organized severe thunderstorms are not forecast on Friday. ...Synopsis... 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. ..Leitman.. 02/10/2021
