Areas affected...portions of west-central Texas southward toward the
Rio Grande

Concerning...Tornado Watch 49...

Valid 130950Z - 131045Z

The severe weather threat for Tornado Watch 49 continues.

SUMMARY...The severe threat continues across WW 49.

DISCUSSION...Convection has generally struggled to deepen across the
WW area this morning, although one cell recently crossed the Rio
Grande near DFX.  This storm is surviving despite weak inhibition,
and has a threat of all modes of severe as long as it can persist.

Uncertainty persists with regard to the extent of convection across
the region. However, it appears that severe convection will remain
possible through the entirety of the valid WW period as the region
remains under the grazing influence of ascent from a mid-level wave
over New Mexico/northern Mexico.  It is also possible that
convection moving eastward from Terrell County may interact
favorably with the warm frontal zone near that region and pose a
severe threat as well.  PFCs/profiles remain supportive of organized
convection favoring all modes of severe - thus the severe threat
across WW 49 continues.
