Mesoscale Discussion 1872
NWS Storm Prediction Center Norman OK
0523 AM CST Thu Dec 24 2020
Areas affected...central FL Panhandle
Concerning...Severe potential...Watch unlikely
Valid 241123Z - 241330Z
Probability of Watch Issuance...20 percent
SUMMARY...The threat for a supercell or two moving ashore from the
Gulf of Mexico may occur this morning, but only a limited area
(confined to near the beaches) and the activity transitioning from
surface-based to elevated, will likely preclude the need for an
additional tornado watch.
DISCUSSION...Radar mosaic shows band of quasi-discrete convection
south of Pensacola ahead of the squall line near Mobile Bay and
approaching the FL Panhandle. The residual influence of a surface
ridge over the northeast Gulf Coast has been slow to abate with
relatively cool temperatures ranging from the lower 50s in the
eastern Panhandle to the lower 60s in the western Panhandle. The
lack of stronger destabilization ahead of the approaching storm
activity will likely contribute to storms not intensifying
appreciably as they move into a more hostile air mass. Nonetheless,
an isolated risk for a strong/damaging gust with the discrete
activity (relatively low), or the squall line later this morning,
could yield a localized severe risk. However, the spatial extent
and overall magnitude of this marginal threat will likely preclude a
tornado watch.
