Areas affected...central portion of the FL Peninsula

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

Valid 112046Z - 112245Z

Probability of Watch Issuance...20 percent

SUMMARY...Widely scattered, weakly rotating deep convection will
probably persist for the next 1-2 hours before the onset of slight
nocturnal cooling. As large-scale ascent increases this evening, a
subsequent reintensification of storm activity is expected. A
tornado risk may develop with this evening storm activity. It is
uncertain regarding the timing for a possible tornado watch.

DISCUSSION...Radar/satellite imagery shows a destabilized boundary
layer featuring deep-moist convection over central portions of the
FL Peninsula. This convection has developed south of a stationary front/baroclinic zone draped west to east across the north-central
part of the peninsula. Surface observations show temperatures
generally in the upper 70s with dewpoints in the 68-70 deg F range
north of the boundary, whereas south of the boundary temperatures
range through the 80s and dewpoints are in the mid 70s.=20=20

Late afternoon 88D VAD data shows a veering and gradually
strengthening wind profile in the lowest 8 km. Flow is modest in
the lowest 4-6 km currently, but is expected to slowly intensify
through the evening and lead to a gradual enlargement of the
hodograph. Given the expected arrival of stronger large-scale
forcing for ascent later this evening into the overnight, the
forecast for greater supercell coverage/intensity is anticipated to
coincide with this process. In the meantime, brief rotation may
occur for the next 1-2 hours with the focus perhaps concentrating
near the temperature gradient/front.
