951 ACUS11 KWNS 100911 SWOMCD SPC MCD 100911 FLZ000-GAZ000-ALZ000-101115- Mesoscale Discussion 0745 NWS Storm Prediction Center Norman OK 0411 AM CDT Fri May 10 2024 Areas affected...Far Southeast Alabama...Southern Georgia...Northern Florida Concerning...Severe Thunderstorm Watch 226...229... Valid 100911Z - 101115Z The severe weather threat for Severe Thunderstorm Watch 226, 229 continues. SUMMARY...A wind-damage, hail and isolated tornado threat will be likely across parts of the eastern Gulf Coast region this morning. As a severe MCS approaches the eastern edge of WW 229, new weather watch issuance may become necessary. DISCUSSION...The latest mosaic radar imagery shows a well-developed severe MCS from the far western Florida Panhandle into far southeast Alabama. This feature will continue to move east-southeastward along a gradient of moderate instability across the Florida Panhandle and southern Georgia. The latest WSR-88D VWP at Tallahassee, FL has 0-6 km shear of 55 to 60 knots suggesting that supercells and bowing line segments will be likely within the stronger parts of the MCS. The VWP also has 0-3 km storm-relative helicity near 150 m2/s2 which should be sufficient for an isolated threat for a brief tornado. The severe threat is expected to impact southeast Georgia and the northern Florida Peninsula within a few hours, where weather watch issuance may be needed. ..Broyles/Guyer.. 05/10/2024 ...Please see www.spc.noaa.gov for graphic product...
