Areas affected…Tampa Bay vicinity
Concerning…Tornado Watch 708…
Valid 121553Z – 121800Z
The severe weather threat for Tornado Watch 708 continues.
SUMMARY…The greatest risk for a brief tornado may focus near the
greater Tampa Bay vicinity through 200pm (1800 UTC).
DISCUSSION…Recent surface analysis indicates a very moist/buoyant
airmass is located over the west-central portion of the FL Peninsula
with mid-upper 80s deg F temperatures and near 80 deg dewpoints.
This airmass was sampled by the 12 UTC TBW raob and little change
has likely occurred thermodynamically except for slightly warmer
surface temperatures. As a larger cluster of the convection west of
Tampa Bay moves towards the bay over the next 1-2 hours, expecting
intermittent/transient rotation with the stronger updrafts embedded
within the larger convective cluster. 40-kt southwesterly 1-km AGL
flow will maintain sufficiently enlarged hodographs for at least the
next few hours and potentially favor transient low-level mesocyclone
development capable of an isolated risk for near-shore
waterspouts/tornadoes. It is unclear whether some of the focused
tornado risk will be maintained as this activity moves farther
inland into the central portions of the peninsula.
