Areas affected...North FL and far south GA
Concerning...Tornado Watch 220...
Valid 092036Z - 092130Z
The severe weather threat for Tornado Watch 220 continues.
SUMMARY...While the bulk of damaging wind/brief tornado threat
appears to be shifting off the Georgia coast, localized strong gusts
may linger into parts of northeast Florida. A downstream watch
issuance appears unlikely.
DISCUSSION...The southeastward-propagating portion of the broad
arcing MCS across south GA has recently moved just offshore to along
the far southeast GA coast. This was responsible for a swath of
damaging winds and brief tornado reports, with measured gusts up to
48 kts. Given modest low-level shear in the 18Z TLH sounding, and
even weaker values noted in the more recent VWP data, convective
outflow has surged well ahead of the MCS, especially with western
extent. Still, with the presence of low to mid 90s surface
temperatures and ample buoyancy ahead of the outflow, it is
plausible that locally strong gusts may accompany deeper convection
before it likely wanes during the early evening.
