   Areas affected...Portions of southeast Mississippi and southwest
   Alabama

   Concerning...Tornado Watch 29...

   Valid 171702Z - 171800Z

   The severe weather threat for Tornado Watch 29 continues.

   SUMMARY...A strong tornado threat will increase from Wayne county,
   Mississippi to Marengo and Wilcox counties in Alabama over the next
   1-2 hours.

   DISCUSSION...Shower activity through the morning has continued to
   deepen and a strong storm has developed in Jones County, MS. This
   storm has quickly exhibited low-level rotation which is indicative
   of the favorable low-level shear profile in this region. SPC
   mesoanalysis shows an area of 300 to 400 m2/s2 of 0-3km SRH in this
   region which is a result of southeasterly surface winds in local
   observations in this area and a 50 knot south-southwesterly
   low-level jet around 1.5km to 2km sampled by the KMOB and KDGX VWP. 
   The ongoing storm in this region in addition to any subsequent
   development could pose a significant tornado threat given the
   aforementioned favorable low-level shear profile and STP values
   around 2 to 3.
