   Areas affected...MS Delta...southern AL and GA...FL Panhandle

   Concerning...Tornado Watch 3...4...

   Valid 022336Z - 030130Z

   The severe weather threat for Tornado Watch 3, 4 continues.

   SUMMARY...The threat for damaging wind and isolated tornadoes
   continues across the watch areas.

   DISCUSSION...Surface analysis shows a warm front from southeastern
   AL across southern GA, with 65-70 dewpoints to the south and
   relatively stable and dry air to the north. Meanwhile, a cold front
   continues to surge eastward from central AL southwestward into
   southeast LA, accompanied by a line of thunderstorms with gusty

   The main tornado threat area remains along the warm front, where
   cells intersecting the front have shown persistent areas of
   rotation. VWPs from southeast AL show large looping low-level
   hodographs with 0-1 km SRH on the order of 250 m2/s2. This, along
   with ample moisture, should continue to support a risk of a
   transient tornado as cells interact with the warm front. However,
   increasing rain and storms from the west will likely disrupt storm
   mode later this evening, with the main forcing for ascent with the
   upper trough also lifting away from the area.
