   Concerning...Tornado Watch 11...12...

   Valid 161132Z - 161330Z

   The severe weather threat for Tornado Watch 11, 12 continues.

   SUMMARY...Severe wind gusts and an isolated tornado threat will be
   possible as a squall line moves eastward across the remainder of
   Georgia this morning. Southern South Carolina will also be affected.
   Weather watch issuance may become necessary later this morning, to
   the east of the ongoing watches.

   DISCUSSION...The latest mosaic radar imagery shows a squall line
   located in Georgia from Albany northeastward to about 50 statute
   miles west of Augusta. The line is located ahead of a fast-moving
   cold front. Surface dewpoints ahead of the line are mostly in the
   60s F, with the RAP showing weak instability in place. In spite of
   this, the line has remained organized likely due to strong
   large-scale ascent associated with an approaching trough, and
   frontal forcing. Short-term model forecasts suggest the line will
   remain intact for several more hours this morning, as it approaches
   the Atlantic coast. The strong low to mid-level flow, evident on
   regional WSR-88D VWPs, will likely enable the line to produce severe
   gusts, especially with bowing segments that form within the line
   itself. Very strong low-level shear will also likely support an
   isolated tornado threat in the short-term.
