MD 0750 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR PORTIONS OF NORTHERN FLORIDA
Mesoscale Discussion 0750
NWS Storm Prediction Center Norman OK
0712 PM CDT Fri May 10 2024
Areas affected…portions of northern Florida
Concerning…Severe potential…Watch unlikely
Valid 110012Z – 110115Z
Probability of Watch Issuance…5 percent
SUMMARY…An isolated damaging gust could accompany any ongoing
storms over the next few hours, and a waterspout cannot be ruled out
along coastal areas. The severe risk should remain isolated and a WW
issuance is not expected.
DISCUSSION…A cluster of thunderstorms is currently traversing the
Big Bend area of northern FL amid a warm and moist low-level
airmass. Surface temperatures in the low 80s F amid 70+ F dewpoints
yield over 2000 J/kg of SBCAPE on the cool side of a residual
baroclinic boundary, where storm maturation could occur. Given the
presence of 50+ kt effective bulk shear values (driven by elongated
hodographs with modest low-level curvature), transient supercells
may develop from the ongoing cluster of thunderstorms. Confidence in
this scenario is modest at best. However, any storm that can mature
in this environment could produce a damaging gust or two, and a
waterspout could also form close to the coastline. The best chance
for a gust or waterspout would be in the next few hours, before
nocturnal cooling will support boundary layer stabilization and a
decrease in thunderstorm potential. Since the severe threat should
be sparse at best, a WW issuance is not expected.
