Mesoscale Discussion 2187
NWS Storm Prediction Center Norman OK
0106 AM CDT Mon Oct 27 2025
Areas affected...Parts of the western Florida Panhandle
Concerning...Severe potential...Watch unlikely
Valid 270606Z - 270830Z
Probability of Watch Issuance...20 percent
SUMMARY...A localized risk of brief tornadoes/waterpsouts will
continue through the early morning hours while spreading eastward
across the western Florida Panhandle. Given the localized and and
conditional nature of the risk, a watch is not expected.
DISCUSSION...The latest surface analysis shows a mesoscale
low/frontal wave over the far western FL Panhandle. A marine front
extends eastward across the remainder of the southern FL Panhandle
-- demarcating the northern bound of upper 60s to lower 70s
boundary-layer dewpoints. Ahead of the frontal wave, the EVX VWP is
sampling 35-kt east-southeasterly flow at 0.5 km AGL, which is
yielding a clockwise-curved low-level hodograph (150-180 m2/s2 0-500
m SRH per EVX). As the frontal wave tracks eastward along the marine
front, a forced confluence zone/low-level warm-advection plume will
continue supporting thunderstorm development across the FL Panhandle
through the early morning hours. Given the implied enhanced
low-level streamwise vorticity and relatively moist boundary layer,
transient supercell structures will continue to pose a risk of brief
tornadoes/waterspouts. However, poor lapse rates and a very narrow
zone of surface-based effective-inflow-layer air should keep the
overall threat localized and conditional -- precluding the need for
a watch.
