Areas affected...Portions of the Rio Grande Valley

Concerning...Severe potential...Watch likely=20

Valid 290047Z - 290215Z

Probability of Watch Issuance...80 percent

SUMMARY...Severe wind gusts near 60-70 mph and marginally severe
hail will accompany a developing MCS through the late evening hours.

DISCUSSION...Several robust updrafts, and a couple of supercells,
will continue moving eastward off the higher terrain of Chihuahua
Mexico. Cell mergers appear likely, and the downstream environment
remains favorable for maintenance considering easterly surface winds
around 15 to 20 kt. Convergence zone balance is anticipated between
this surface flow and westerly 0-3 km shear vectors. In addition, a
very unstable and undisturbed air mass remains in place across south
Texas.
