   Areas affected...Southeast Texas and Southwest Louisiana

   Concerning...Tornado Watch 32...

   Valid 141321Z - 141515Z

   The severe weather threat for Tornado Watch 32 continues.

   SUMMARY...A severe threat will likely continue this morning as a
   line of storms moves eastward across southeast Texas and the middle
   Texas coast. The severe threat may affect far southeast Texas and
   southwest Louisiana by late this morning. A new weather watch may
   need to be issued across the Beaumont and Lake Charles vicinities as
   the line moves into the far eastern part of WW 32.

   DISCUSSION...The latest radar trends show a continuous line of
   strong to severe thunderstorms extending from near Bryan/College
   Station south southwestward to about 25 statute miles west of the
   Houston metropolitan area. The southern part of the line extends
   southwestward from near Victoria to about 20 miles west of Corpus
   Christi. The latest HRRR run suggests the northern part of the line
   will remain intact and move eastward across the Houston area over
   the next 2 to 3 hours. The latest estimates move this part of the
   line to the eastern edge of tornado watch 32 by around 16Z. Although
   weak instability is located to the east of the current watch,
   moisture advection and surface heating will take place this morning.
   As a result, conditions should become favorable for severe
   thunderstorms in the Beaumont vicinity eastward to near Lake Charles
   by late morning into early afternoon where a new weather watch may
   be needed. A tornado threat along with wind damage and hail will be
   possible with the stronger elements within the line.
