DISCUSSION

Issued at 119 PM CDT Wed Jun 17 2026

Tropical Storm Arthur will continue to push to the northeast away from the Middle Texas Coast. The only continuing threats from this will be the increased risk for rip currents and minor coastal flooding through this evening. There is some potential that we could see minor coastal flooding once again due increased swell periods during high tide Thursday morning, but with low confidence due to the offshore flow, will hold off on issuing anything.

An upper level ridge continues to build across South Texas tonight, with temperatures soaring into the triple digits over and west of the Coastal Plains. With relative humidity values of 40-75%, heat indices will reach 115-120! An Excessive Heat Warning will be in effect Thursday afternoon for all but the barrier islands where a Heat Advisory will be in effect.

Weakness in the high pressure will allow a shortwave to move across the area Friday night through Saturday night. This will reintroduce a low to medium (20-40%) chance for showers and thunderstorms across the Brush Country. Rainfall amounts are not anticipated to be anywhere near what we have seen in the past few days as we will be in a much drier regime.

AVIATION

(18Z TAFS) Issued at 119 PM CDT Wed Jun 17 2026

Currently seeing MVFR conditions at ALI/VCT and VFR at CRP/COT/LRD as TS Arthur moves away. Winds generally out of the southeast through the period. Expect VFR to continue overnight in COT/LRD. Will see MVFR CIGs in CRP and VCT overnight, while ALI will fall to MFVR/IFR due to fog.
