DISCUSSION

Issued at 1250 AM CDT Mon Jun 8 2026

Subtropical jet over the area will gradually weaken as upper level ridging from the west slowly pushes in. Moisture from the gulf continues to keep the PWs in the area relatively high at or just above 2 inches. Today is probably the best chances of any showers being right now to the early morning hours along the coast, then another chance of showers and storms in the afternoon hours. There is still a limited chance of some heavy rainfall in the stronger storms leading to street flooding in areas that have had repeated rounds of rain but the threat seems relatively minimal compared to the previous days. High pressure from the gulf will slowly move in and help suppress but not completely remove chances of convection. However since there will be less rain and cloud cover, high temperatures will climb from the upper 80s to low 90s to the low to mid 90s as the week progresses, with heat index values reaching the mid to upper 100s by late this week.

High risk of rip currents still remain a concern as persistent onshore winds continues, however the winds will begin to decrease later this week which will help decrease it down to more of a moderate risk.

AVIATION

(12Z TAF Issuance) Issued at 525 AM CDT Mon Jun 8 2026

Prevailing MVFR ceilings at most terminals this morning with isolated pockets of IFR ceilings. Expect ceilings to improve to VFR by the late morning hours. A band of lingering light rain along and south of the I-10 corridor is anticipated to persist through most of the morning hours before gradually dissipating. In the early afternoon, there is potential for isolated thunderstorms to develop mainly north of I-10. Confidence is not high enough to include any thunder in this set of TAFs, but did include some PROB30's for SHRA as greatest confidence on afternoon activity is CXO and northward. Winds will be southeasterly around 10-15 kt with gusts up to 18-23 kt at times through the afternoon. Any lingering rain will dissipate around 00Z with MVFR to IFR ceilings filtering in again overnight into Tuesday morning.
