Areas affected...central portions of the Florida Panhandle

Concerning...Tornado Watch 685...

Valid 261620Z - 261815Z

The severe weather threat for Tornado Watch 685 continues.

SUMMARY...Local risk for brief tornadoes will continue -- with
greatest short-term potential over central portions of the Florida
Panhandle.

DISCUSSION...Latest surface analysis reveals a nearly stationary
north-south trough -- acting as a pseudo warm front and, as such,
source of enhanced low-level vorticity -- extending from the
Franklin/Gulf County vicinity on the Florida Coast, northward across
far western Georgia and into the southern Appalachians.  This
boundary reflects the discontinuity between the moist/tropical
airmass to the east, and the continental airmass to the west.
Several/continued brief low-level spin-ups have been observed over
the past couple of hours within this zone, and expect this local
enhancement of tornado potential to continue over the next couple of
hours, given increasingly favorably low-level flow and the nearly
stationary character of this north-south boundary.
