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.
