ZCZC SPCSWOMCD ALL ACUS11 KWNS 151245 SPC MCD 151245 GAZ000-ALZ000-MSZ000-151415- Mesoscale Discussion 0256 NWS Storm Prediction Center Norman OK 0745 AM CDT Fri Mar 15 2024 Areas affected...East-central MS into central/northeast AL and northwest GA Concerning...Severe Thunderstorm Watch 51... Valid 151245Z - 151415Z The severe weather threat for Severe Thunderstorm Watch 51 continues. SUMMARY...A localized damaging-wind threat may persist through the morning. DISCUSSION...A long-lived QLCS is gradually moving eastward across parts of MS/AL into northwest GA this morning. Within the larger QLCS, shorter line segments have occasionally taken on a north-south orientation through the early morning, accompanied by some increase in organization and damaging-wind potential. This general trend may persist into mid morning, with an isolated damaging-wind threat accompanying the stronger line segments that do not get undercut by outflow. Some threat may spread outside of WW 51 into northwest GA, though the need for downstream watch issuance is uncertain, due to weaker instability with northeastward extent (as noted in the 12Z FFC sounding and objective mesoanalyses). Farther southwest, some uptick remains possible from east-central MS into central AL, where MLCAPE of 500-1000 J/kg and favorable deep-layer shear remain in place this morning. Local watch extension may need to be considered for parts of MS/AL, depending on short-term convective trends. ..Dean/Thompson.. 03/15/2024 ...Please see www.spc.noaa.gov for graphic product...
