DISCUSSION

Issued at 116 AM CDT Tue Jul 14 2026

Moisture continues to stream into the area on a strong south to southeasterly low level jet. PWAT values on 00Z sounding hit 2.2 inches, but without a good focus mechanism, convection will continue to be limited through Tuesday. An elongated trough remains situated north of our area where flooding rains are expected over the next 24 to 48 hours. We did see a few showers and storms along the sea breeze this afternoon, and will expect a similar situation tomorrow. Some guidance suggests the trough dipping down toward the Victoria Crossroads and increasing rain chances there. By Tuesday night into Wednesday the boundary does sag south into the area and we will see an uptick in PoPs to 50-60%, especially north. This will really hinge on how far south the boundary makes it. There is ample moisture to work with, so any convection that does move into/develop in our area will be able to produce locally heavy downpours. Area wide rainfall totals are generally low, under half an inch, though do peak a bit higher in the Cotulla area. Probabilities of an inch or more of rain are up to 50% for around Cotulla, and much lower for most of the area. No plans to issue a flood watch at this time as uncertainty is very high and FFG does not support more than an isolated risk for flash flooding.

By Thursday into Friday, mid level forcing pushes to the west and relatively drier deep layer air settles in lowering rain chances. Just an isolated sea breeze shower/storm would be in the forecast from Thursday night into the weekend. Temperatures early in the period will be a few degrees below normal, then return to near normal levels by the weekend.

AVIATION

(12Z TAFS) Issued at 555 AM CDT Tue Jul 14 2026

Convection continues to our north, skirting our northern sites. So far, COT and VCT have remained rain-free, but have included PROB30 groups for the potential for showers and thunderstorms at these terminals. A mixture of MVFR and VFR conditions will persist this morning before predominately VFR conditions develop. Seabreeze convection is possible this afternoon so have included another PROB30 group where convection is most likely.

MARINE

Issued at 116 AM CDT Tue Jul 14 2026

Generally gentle to moderate (BF 3-4) southeasterly-southerly winds with seas running 2 to 3 ft should persist through mid-week. Winds become more moderate to fresh in the beyond Wednesday with seas increasing to 4-5 ft. Generally low to medium (25 to 40 percent) rain chances are expected through early Thursday.
