Areas affected...parts of central and southern Florida

Concerning...Severe Thunderstorm Watch 91...

Valid 111724Z - 111930Z

The severe weather threat for Severe Thunderstorm Watch 91
continues.

SUMMARY...Severe risk continues locally across parts of central
Florida -- within WW 91 -- and will gradually shift southward
requiring new WW consideration across much of south Florida.

DISCUSSION...Latest radar loop shows a band of storms sagging
southward across central Florida, with occasionally stronger
storms/convective segments noted.  As outflow associated with this
band shifts steadily southward, the primary zone of severe risk will
likewise shift south -- and eventually out of the current WW.

Meanwhile, as the very moist south Florida airmass continues to
warm/destabilize, additional/cellular development is occurring south
of the main convective band.  Given sufficient shear across the
area, a few of these storms could produce gusty winds and hail,
prior to the arrival of storms from the north.  Given these trends,
a new WW will likely be required in the next 60 to 90 minutes,
across much of south Florida.
