Areas affected...Far South Texas

Concerning...Severe potential...Watch unlikely=20

Valid 091438Z - 091615Z

Probability of Watch Issuance...5 percent

SUMMARY...Isolated severe wind gusts are possible for the next 1 to
2 hours.

DISCUSSION...A (likely) slightly elevated supercell has moved across
Hidalgo county this morning with a recent measured wind gust of 54
knots in McAllen, Texas. The 12Z KBRO RAOB sampled this environment
with 2500 J/kg MUCAPE and 47 knots of effective shear with a PWAT of
2.00". This should be sufficient to maintain some isolated wind
threat for the next 1 to 2 hours. On the storm scale, an additional
stronger core has developed in western Willacy county. These
stronger cores, in addition to additional development near the Rio
Grande, should support isolated areas of intense water loading and
the potential for damaging wind gusts for the next 1 to 2 hours
before these storms move offshore and the threat subsides.
