Mesoscale Discussion 0725 NWS Storm Prediction Center Norman OK 0210 AM CDT Thu May 09 2024 Areas affected...Tennessee...Northeast Mississippi...Northern Alabama...Far Northwest Georgia Concerning...Tornado Watch 213...214... Valid 090710Z - 090915Z The severe weather threat for Tornado Watch 213, 214 continues. SUMMARY...A threat for wind damage, isolated large hail and a few tornadoes will continue across western and middle Tennessee over the next couple of hours. The threats are expected to spread into parts of northeast Mississippi, northern Alabama and far northwest Georgia. A short-term extension or new weather watch issuance will be needed as the expiration of WW 213 approaches at 08Z. DISCUSSION...The latest hi-resolution radar imagery from Nashville, TN shows a large MCS with numerous severe storms, located across the Tennessee Valley. An undisturbed airmass is currently evident from southern middle Tennessee southward into the northern Gulf Coast states, where the RAP is analyzing MLCAPE in the 1500 to 2500 J/kg range. The Huntsville, AL WSR-88D VWP has 0-6 km shear near 40 knots, with 0-3 km storm-relative helicity of 300 m2/s2. This will support a tornado threat, with discrete supercells that remain out ahead, or with the more intense cells embedded within the MCS. Supercells could also be associated with an isolated large-hail threat. A wind damage threat will also be likely, especially with bowing line segments. ..Broyles.. 05/09/2024 ...Please see www.spc.noaa.gov for graphic product...
