ZCZC SPCSWOMCD ALL ACUS11 KWNS 101216 SPC MCD 101216 LAZ000-MSZ000-101345- Mesoscale Discussion 0412 NWS Storm Prediction Center Norman OK 0716 AM CDT Wed Apr 10 2024 Areas affected...Southern LA into Far Southwest MS Concerning...Tornado Watch 100...101... Valid 101216Z - 101345Z The severe weather threat for Tornado Watch 100, 101 continues. SUMMARY...The threat for strong to severe (60 to 80 mph) gusts and tornadoes remains from southern Louisiana and far southwest Mississippi. DISCUSSION...Ongoing convective line exhibited a notable surge over the past half hour, with storm motion now estimated at 50-55 kt. Strong to severe gusts continue within this line, as evidenced by the impressive velocity signature from KLCH as well as the measured 55 kt at WFO LCH. In addition to this surge, the storm motion has trended a bit more northeasterly, becoming even more perpendicular to the deep-layer vertical shear. Expectation is for this line to continue east-northeastward for at least the next few hours. Gusts from 60-80 mph remain possible within the line, with line-embedded tornadoes possible as well. Warm-air advection continues ahead of the line, with a few more organized cells manifesting within this regime. The overall parameter space, which is characterized by around 1000 J/kg of MLCAPE, 50 kt of deep-layer vertical shear, and 200 m2/s2 of 0-1 km SRH, supports a continued threat for supercells capable of all hazards, including tornadoes. Main deterrent for storm organization will be interference with other cells. The warm layer around 700 mb observed on the 12Z LIX sounding could act to suppress updraft intensity a bit as well. Even so, the general expectation is for the development of isolated to scattered supercells capable of all severe hazards. ..Mosier.. 04/10/2024 ...Please see www.spc.noaa.gov for graphic product...
