Mesoscale Discussion 2199

Areas affected...portions of the northern Florida Peninsula

Concerning...Severe potential...Watch unlikely=20

Valid 261822Z - 261915Z

Probability of Watch Issuance...5 percent

SUMMARY...A damaging gust or two is possible this afternoon. The
severe threat should be sparse at best, and a WW issuance is not
expected.

DISCUSSION...A loosely organized line of multicells continues to
gradually progress eastward across the northern FL Peninsula amid
weak tropospheric flow. Given weak vertical shear, storms are
expected to remain loosely organized, joined only by a singular cold
pool. These storms are preceded by a heated boundary layer, where
surface temperatures are reaching 90 F amid mid 70s F dewpoints,
contributing up to 3500 J/kg SBCAPE (per 18Z mesoanalysis). With
precipitable water values also exceeding 2 inches, water-loaded
downdrafts should be common with the stronger storms, and a damaging
gust or two may occur. However, the severe threat should remain
sparse and a WW issuance is not anticipated.
