DISCUSSION

Issued at 120 PM CDT Tue Jun 9 2026

Mid level high pressure ridge axis is currently draped N-S across East TX down to Deep S TX and is keeping convection from developing. Very isolated weak showers have managed to briefly develop and am expecting this trend to continue through the remainder of the afternoon as the sea breeze moves inland. Models prog a weak mid level inverted trough to move west across S TX on Wednesday. This feature combined with low level moisture and the sea breeze will help produce isolated showers or weak thunderstorms Wednesday. There is a 15-30% chance of this occurring. Conditions will be slightly drier Thursday as the mid level ridge moves across the region. Friday the sea breeze looks to be a little more active, but rain chances look better over the weekend. This is due to deepening moisture with PWATs increasing to 2.2-2.3 inches, combined with a slightly stronger mid level inverted trough tracking west across the region. The probability of showers and thunderstorms increases to 20- 40% over the weekend.

There is a moderate risk of heat related impacts through the week and weekend due to temperatures in the 90s combining with high humidity, leading to heat indices ranging 100-110 degrees.

The rip current risk remains moderate tonight, becoming low Wednesday and is expected to remain low through Thursday. Swell periods are forecast to increase to 8-9 seconds by the end of the work week, which coincides with astronomically higher tides and nearing a new moon. This may result in a high rip current risk as well as minor coastal flooding by Friday into the weekend.
