Areas affected...parts of southern AL...southwest/central GA...into
the western FL Panhandle
Concerning...Tornado Watch 132...
Valid 062048Z - 062215Z
The severe weather threat for Tornado Watch 132 continues.
SUMMARY...Several bands of strong to severe storms will remain
capable of damaging gusts and a couple tornadoes. Some local
extensions of WW132 may be needed, but the downstream threat appears
more limited.
DISCUSSION...As of 2040 UTC, regional radar observations indicate a
band of convection across southeastern AL and west-central GA
continues to show embedded supercell and bowing structures capable
of damaging gusts and tornadoes. This should continue for a couple
more hours as storms approach the eastern edge of the Tornado Watch
132. Areal extensions of a few counties may be needed as storms
begin to outrun the watch. As storms continue farther east, a
gradual decrease in buoyancy should favor weakening into the evening
hours. Until then, damaging gusts and a couple tornadoes remain
possible.
To the southwest, a second smaller band of convection across
southern AL will likely maintain intensity for a few more hours this
afternoon. A few more isolated cells have also developed farther
east within the warm sector across southwest GA and the northern FL
Panhandle. 1500-2000 J/kg of MLCAPE and 40+ kt of effective shear
could support a continued severe threat into this evening. This
matches with some hi-res guidance that shows a gradual expansion of
strong storms into southwest GA and possibly northern FL. However,
forcing for ascent is some what nebulous and storm coverage has
remained more isolated thus far. With storms approaching the
southeast corner of WW132 in the next few hours, some consideration
may be given to a small downstream watch. However the extent of the
severe risk and need for any new watches is currently unclear.
