KEY MESSAGES

Issued at 618 PM CDT Thu Sep 24 2026

- Dry and hot conditions through the weekend.

- Attention turns to an potential "cold" front towards the middle and latter half of next week, bringing slightly cooler temperatures and widespread rain chances.

DISCUSSION

Issued at 115 PM CDT Thu Sep 24 2026

The summer swelter continues through this weekend with above normal temperatures and dry conditions. Hot and near record temperatures continue into the first half of next week, but the overall conditions become a little more favorable for streamer showers in the morning and 20 percent chance for afternoon sea-breeze thunderstorms.

The big talking point for next week is the potential arrival of a "cold" front late Wednesday into Thursday. However, there is significant uncertainty regarding the southern extent of the front, the strength, and the timing.

Complicating the situation is Hurricane Polo and how it will interact with the parent trough as it moves across the Desert Southwest early next week. There are a couple different possible scenarios, the tropical system could help to deepen the trough, which would make it more likely to track farther south and then bring rain to the region, or it may not have much impact on the deepening of the trough, keeping it farther north, and thus a better chance of the front washing out before it reaches South Texas.

Regardless, it does look like we will see increased chances for rain later next week and some slightly cooler temperatures.

AVIATION

(00Z TAFS) Issued at 618 PM CDT Thu Sep 24 2026

Mainly VFR conditions expected during this TAF period. Some models are hinting at a 35-55% chance for MVFR CIGs out west during the early morning and a low chance for fog at VCT. Due to low confidence have opted to leave the lower CIGs out of TAFs for now. Otherwise, winds in the morning will be light and variable giving way to easterly/southeasterly winds during the afternoon/evening around 10- 15KT with gusts up to 20KT.

MARINE

Issued at 115 PM CDT Thu Sep 24 2026

A gentle to moderate (BF 3-4) east to southeasterly flow is expected to persist through the the weekend with seas between 2-4 feet. A moderate to near fresh (BF 4-5) southeast flow picks back up Monday and Tuesday ahead of an approaching cold front with seas around 3 to 5 feet. A cold front looks approach the waters next Wednesday or Thursday, shifting winds around to the east with significantly increased chances for precipitation. Confidence remains low on the strength and timing of the cold front, so stay tuned for updates as we get closer.

FIRE WEATHER

Issued at 1210 AM CDT Thu Sep 24 2026

Humidity levels remain elevated with minimum RH values staying above 35% for counties out west and winds are expected to remain light. Thus elevated fire weather conditions are not expected at this time.
