   Areas affected...south Texas

   Concerning...Tornado Watch 437...

   Valid 201042Z - 201215Z

   The severe weather threat for Tornado Watch 437 continues.

   SUMMARY...A tornado risk may persist another couple of hours across
   south Texas before waning through the morning hours.

   DISCUSSION...Convection has shown very minor rotation over the past
   several hours across south Texas. Overall intensity has remained
   weak, and lightning trends have decreased early this morning.
   Forecast guidance suggests low-level shear will weaken through
   early/mid-morning. Overall expectation is that a new tornado watch
   will not be needed, though a local extension in time may be
   considered if any convection shows signs of intensification over the
   next hour.
