Mesoscale Discussion 0810 NWS Storm Prediction Center Norman OK 0227 PM CDT Wed May 17 2023 Areas affected...southern AL Concerning...Severe potential...Watch unlikely Valid 171927Z - 172130Z Probability of Watch Issuance...5 percent SUMMARY...Isolated strong to locally severe thunderstorms capable of 45-60 mph gusts will potentially yield pockets of wind damage. DISCUSSION...Visible satellite/radar mosaic imagery shows a developing cluster of thunderstorms moving slowly east-southeast over southwest AL. Surface observations ahead of the activity indicate temperatures have warmed into the upper 80s with dewpoints in the upper 60s. Weak westerly tropospheric flow according to KMOB VAD data will favor slow, eastward-moving thunderstorms. Objective analysis shows 1500-2000 J/kg MLCAPE and forecast soundings show a very moist profile. Water-loaded downdrafts will likely be the primary hazard with the stronger cores. Where localized 45-60 mph gusts occur over the next couple of hours (through 2130 UTC/430pm CDT), pockets of wind damage are probable. ..Smith/Grams.. 05/17/2023 ...Please see www.spc.noaa.gov for graphic product...
