MD 2300 CONCERNING TORNADO WATCH 713... FOR SOUTHEAST LA...COASTAL MS/AL
Mesoscale Discussion 2300 NWS Storm Prediction Center Norman OK 1135 PM CST Fri Dec 01 2023 Areas affected...Southeast LA...coastal MS/AL Concerning...Tornado Watch 713... Valid 020535Z - 020700Z The severe weather threat for Tornado Watch 713 continues. SUMMARY...A brief tornado and marginally severe wind/hail will remain possible into the early morning as convection gradually shifts east from southeast LA to coastal portions of MS/AL. DISCUSSION...A pair of lower-end supercells have recently progressed into the Lake Pontchartrain vicinity, with additional deep convection lingering to the southwest in the northern Terrebonne/Lafourche Parish area. A limited severe threat should persist with this convection as it moves east towards the MS/AL coast. Surface-based instability has been subsiding amid overturning and stronger buoyancy relegated to the western Gulf, with MLCAPE holding at or below 500 J/kg east of LA. As such, the overall thermodynamic environment should gradually become less favorable for sustaining supercell structures. In addition, downstream low-level wind profiles as sampled by the KMOB VWP are still fairly modest, although an uptick remains progged during the early morning. This setup will yield a low-probability severe threat continuing east of WW 713, with uncertainty over whether another watch is needed. ..Grams.. 12/02/2023 ...Please see www.spc.noaa.gov for graphic product...

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1250 AM CST Sat Dec 02 2023 Valid 031200Z - 041200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms will be possible on Sunday from Florida northeastward into the eastern Carolinas, but no severe storms are expected. ...DISCUSSION... A trough at mid-levels will move across the central U.S. on Sunday, as southwesterly flow remains in place over the eastern U.S. Ahead of a cold front, a moist airmass will be in place from Florida northeastward into the eastern Carolinas. Isolated thunderstorms will be possible during the day across this moist airmass as surface temperatures warm. However, instability is expected to be insufficient for a severe threat. Elsewhere, no thunderstorm activity is forecast across the continental U.S. Sunday and Sunday night. ..Broyles.. 12/02/2023 Read more
