Valid 230932Z - 231100Z
The severe weather threat for Tornado Watch 65 continues.
SUMMARY...An isolated severe threat may persist east of Tornado
Watch 65. A downstream watch will probably be needed.
DISCUSSION...Recent radar trends show occasional low-level rotation
with storms moving onshore across parts of the FL Panhandle Coast.
Based on latest RAP forecast soundings, mid to upper 60s surface
dewpoints will probably be needed to support surface-based storms.
09Z surface observations show adequate low-level moisture has
advanced inland across most of the FL Panhandle ahead of the ongoing
storms, as well as parts of far southeastern AL and southwestern GA.
Strong low-level flow and shear associated with a 40-50 kt southerly
low-level jet will likely support continued updraft rotation, and a
threat for isolated tornadoes and strong/gusty winds. Storms will
approach the eastern bound of Tornado Watch 65 in the next 1-2
hours, and it is scheduled to expire at 11Z (6 AM CDT/7 AM EDT).
Even though instability becomes increasingly marginal with eastward
extent, there may still be enough boundary-layer instability to
support a continued severe threat east of the current watch,
particularly along/near the coast of the FL Panhandle. Accordingly,
a downstream Tornado Watch will probably be needed by 11Z.
