DISCUSSION

Issued at 142 PM CDT Mon Sep 14 2026

A few showers and storms today, but mainly just a stray shower/storm. Satellite trends not showing a low inland with the sea breeze today, but recent history makes it hard to say there's no chance. Thus have a 20% chance along the seabreeze for the afternoon. Otherwise, the rest of the afternoon will feature hot temps similar to the past several days. Heat advisory remains in effect through the afternoon and a few sites have reached advy criteria as of early afternoon.

Overall picture with high pressure in place remains. The ridge center is north of the area with a few short waves rotating east to west under the ridge. For Tuesday into Wednesday moisture levels look too low to warrant more than low PoPs (mainly Tuesday). Moisture levels will increase though Thursday - topping over 2", even 2.25" along the coast which is pushing PoPs up in some models, including the NBM. Feel though that some guidance may be a bit too excited, and have capped PoPs over land closer to 50%. Expect scattered showers and storms, but not a widespread rain out day. Also, rainfall totals are not expected to be impressive. Probabilities of greater than 0.1" are pretty good along the coast, but when you look at greater than 0.5", they are near zero. Even a little rain is better than none, though!

Hot temperatures are expected again on Tuesday, but deep moisture decreases quite a bit and as a result of mixing, surface RH will also decrease more efficiently than today, so we're only borderline on a heat advisory tomorrow. It may be necessary, but confidence isn't there at the moment. As we head toward Wednesday and Thursday we should see at least a bit of relief from the upper 90s and temps over 100, but unless showers/storms persist over an area on Thursday, would still expect near to slightly above normal temps. Low temperatures will decrease a bit late in the period with drier air moving in. High temps return to above 100 west and in the mid and upper 90s east for the weekend.

AVIATION

(00Z TAFS) Issued at 550 PM CDT Mon Sep 14 2026

VFR conditions will prevail at all sites through the evening. A brief period of MVFR CIGS is not out of the question for any site, but did include a TEMPO group for LRD, COT and VCT due to model guidance and similar conditions as last night/this morning when MVFR conditions briefly developed and lasted more than a couple of hours. Gusty S-SE winds continue into the evening across the western areas. Winds relax overnight then restrengthen mid to late Tuesday morning across S TX with gusts around 25 knots by Tuesday afternoon.

MARINE

Issued at 142 PM CDT Mon Sep 14 2026

A fresh (BF 5) breeze is expected south of Port Aransas across Corpus Christi and Baffin Bays and out to 20 nautical miles once again this afternoon. Small Craft Should Exercise Caution in the bays and nearshore waters south of Port Aransas through this evening. Otherwise, a gentle to moderate (BF 3-4) onshore flow is expected through the upcoming week. A few showers and storms are possible over the waters today. Rain chances increase to medium to high Wednesday through Friday, then decrease again for the weekend.
