SPC Mesoscale Discussion: Tornado Watch 436…
SUMMARY…Isolated severe thunderstorms remain possible across the watch area, and may spread into southeast Georgia this morning.
DISCUSSION…Storms remain ongoing in a southwest to northeast oriented zone from the western FL Panhandle across much of southern GA. Supercell trends have decreased over the past few hours, but several substantial storms remain ongoing with modest outflow and shear zones noted on radar. Latest surface observations show a gradual northeastward advection of the near 70 F temperatures and upper 60s F dewpoints due to persistent southwesterly flow (50 kt at 1km) which is helping to erode the cooler outflow air. This in turn will allow effective SRH to rise over southeast GA this morning (the VAX VWP currently shows upwards of 300 m2/s2), and will increase the threat of damaging winds or a brief tornado. Storm trends will continue to be monitored for any increase and the need for another watch.
