Valid 251223Z - 251430Z
Probability of Watch Issuance...20 percent
SUMMARY...A few thunderstorms may become marginally severe later
this morning, with hail or wind. But coverage may not warrant a
DISCUSSION...A weak cold front currently extends across south
Florida, with substantial tropical moisture to the south. The 12Z
MFA and KEY soundings both show PW approaching 2" along with
2000-3000 J/kg MLCAPE in place. Further, mid to upper level wind
fields remain strong, which is lengthening hodographs.
Scattered storms currently exist along the front and extending
southwestward over the Gulf, with a few showers ahead of the front
as well. With pockets of heating, a few of these storms could become
marginally severe with hail or wind. However, generally unfavorable
synoptic-scale conditions will ensue throughout the day with the
upper trough lifting away from the area. Thus, the overall threat is
not expected to be widespread or warrant a watch.
