Mesoscale Discussion 2242 NWS Storm Prediction Center Norman OK 0627 PM CST Sun Dec 29 2019 Areas affected...west-central AL Concerning...Tornado Watch 708... Valid 300027Z - 300200Z The severe weather threat for Tornado Watch 708 continues. SUMMARY...A corridor of greater severe potential exists across portions of western AL this evening. Damaging wind gusts and a tornado or two will be possible over the next couple of hours. DISCUSSION...Several areas of weak to moderate rotation have been noted in SRV data over the last 30 minutes from Noxubee County MS to Lamar County AL, both with semi-discrete supercells and bowing segments. A corridor of relatively increased severe potential will exist downstream of this section of the line across western AL over the next 1-2 hours. The 00z RAOB from BMX showed MLCAPE around 400 J/kg with effective SRH greater than 400 m2/s2. This strong shear environment will continue to support organized, rotating convection capable of damaging gusts and possibly a tornado or two in the short term. ..Leitman.. 12/30/2019 ...Please see www.spc.noaa.gov for graphic product...
