   Valid 091248Z - 091445Z

   The severe weather threat for Tornado Watch 215, 216 continues.

   SUMMARY...An isolated wind damage/tornado threat should continue
   this morning across northern Alabama and northern Georgia. The
   threat may spread southward into central Alabama and central
   Georgia, where new weather watch issuance remains possible.

   DISCUSSION...The latest mosaic radar imagery shows an MCS,
   associated with strong to severe storms, located from far northeast
   Mississippi extending eastward into far western South Carolina. A
   moist and unstable airmass is present to the south of the MCS across
   much of the Gulf Coast states. In addition, regional WSR-88D VWPs
   across this airmass have 0-6 km shear near 60 knots and 0-3 km
   storm-relative helicities between 200 and 250 m2/s2. This should
   support an isolated tornado threat with supercells embedded in the
   line, or that develop to the south of the line. A wind-damage threat
   will also be possible with the supercells and the stronger line
   segments. The severe threat is expected to increase later this
   morning as surface temperature warm. For this reason, weather watch
   issuance may be needed to the south of the current watches.
