NWS Storm Prediction Center Norman OK
1038 AM CDT Wed Apr 05 2017
Areas affected...FL Panhandle...GA...Southwest SC
Concerning...Severe potential...Watch likely
Valid 051538Z - 051715Z
Probability of Watch Issuance...95 percent
SUMMARY...Tornado Watch will be issued by 17z to address increasing
severe threat from the eastern FL Panhandle into SC.
DISCUSSION...Boundary-layer cu field is beginning to deepen from the
eastern FL Panhandle into southeast GA as surface temperatures rise
to near 80F. Latest high-res Vis imagery depicts
clustering/towering CU along a corridor from near MAI to near VDI.
Substantial breaks in cloud cover suggest additional heating can be
expected and thunderstorms will likely evolve over the next few
hours. Given the strength of the wind fields and rising instability
there is increasing concern for discrete supercell formation by
early afternoon. Environmental parameters appear favorable for a
few strong tornadoes across this region, in addition to large hail
and damaging winds. Tornado watch will be issued for parts of this
area by 17z.
