SPC Mesoscale Discussion: Severe Potential… Watch Possible

SUMMARY…Storms are expected to develop eastward into southeast AL, the central FL Panhandle and southwest GA overnight. Primary threats will be damaging wind and isolated tornadoes. Trends are being monitored for a possible WW.

DISCUSSION…Broken band of storms from south central AL into the extreme western FL Panhandle continues eastward at around 30 kt. Tendency has been for the storms inland from the coast to out pace the greater low-level jet and destabilization. With exception of the northern end of the line, overall storms appear poorly organized. However, the low-level jet will gradually develop eastward tonight, and resulting moist advection should contribute to northward destabilization with time. Recent observations show dewpoints increasing to the upper 60s over coastal Fl and moisture should continue to increase farther inland with time. This suggests that storms may become better organized later this evening and especially into the overnight with low-level hodographs and effective bulk shear becoming supportive of organized structures capable of damaging wind and isolated tornadoes.
