   Concerning...Severe Thunderstorm Watch 135...136...

   Valid 102208Z - 110015Z

   The severe weather threat for Severe Thunderstorm Watch 135, 136
   continues.

   SUMMARY...Severe wind gusts and large hail are expected with
   convection as it spreads southeast this evening.

   DISCUSSION...Mid-level heights are falling across the Mid South this
   evening as a 500mb speed max digs across eastern KS toward northern
   MS. Left-exit region of this jet appears partly responsible for an
   expanding cluster of thunderstorms along the cold front over western
   TN. Additionally, while the boundary-layer lapse rates are quite
   steep across much of this region, surface temperatures are
   considerably warmer across northern MS into central AL where
   readings are in the lower 80s. As profiles cool aloft, the greatest
   buoyancy should focus across northern MS into northern AL. Frontal
   convection may continue to grow upscale due to the aforementioned
   exit region and thermodynamic profiles favor strong downdrafts, in
   addition to large hail. Severe storms should spread across northern
   MS and northern AL through mid evening.
