Areas affected...northern Florida...southeast Georgia...southern
Concerning...Severe potential...Watch possible
Valid 071641Z - 071845Z
Probability of Watch Issuance...40 percent
SUMMARY...A gradual increase in storm intensity is possible across
northern Florida into southern Georgia over the next several hours,
with at least a localized damaging wind or brief tornado threat.
DISCUSSION...Destabilization is slowly occurring ahead of a
pre-frontal convective band extending from the eastern FL Panhandle
into southern GA. Storms on the leading edge of this band have shown
relative strength at times with transient areas of rotation with
some of the cells. Other deepening showers are over northern FL
where temperatures are approaching 80 F.
Winds aloft will generally increase throughout the day, with
gradually veering low-level winds. The increasing speed shear should
maintain favorable hodographs supporting a few supercells, as well
as a few small bows. VWPs and forecast soundings generally indicate
effective SRH values on the order of 100-200 m2/s2 today.
