(This evening through next Thursday) Issued at 1235 PM CDT Fri Aug 7 2026 If you, like me, have been left out of the rain over the last few days and are beginning to feel like you live in a rain bubble , fret not, for precipitation chances will remain in the 30- 60% chance range each afternoon through at least Tuesday. Your bubble will burst eventually. The region remains embedded in a narrow weakness aloft bisecting two sprawling ridges with one over the four corners region and the Bermuda high over the western Atlantic. This weakness will continue to support daily thunderstorm development once daily convective temps are exceeded (presently being measured around 90 degrees). These will be further enhanced during the afternoon by the inland advancing sea breeze. Mid level moisture is expected to increase further Sunday and Monday as a slug of moisture associated with a weak wave/inverted trough lifts north out of the gulf. This will push precipitation chances even higher (40-80%). The increase in cloud cover and precipitation will keep afternoon highs a few degrees cooler in the upper 80s to lower 90s. The Bermuda high is progged to build westward across the northern gulf coast Wednesday which will drop precipitation chances through the second half of next week. Jones && .AVIATION... (18Z TAFS) Issued at 1235 PM CDT Fri Aug 7 2026 VFR conditions will prevail through the taf period. Showers and thunderstorms will continue to develop through the afternoon intermittently impacting the terminals. These storms will be capable of brief periods of visibility reducing heavy rainfall. Storms will wane through the early evening and should be largely dissipated by 00Z. Guidance is once again indicating the potential for patchy, shallow ground fog early Saturday morning. Any fog that develops will dissipate by 13Z. Another round of scattered showers and thunderstorms will initialize by around 16Z Saturday. Jones && .MARINE... Issued at 1235 PM CDT Fri Aug 7 2026 Light southeasterly winds and low seas will continue through next week as a surface high pressure system ridges across the northern Gulf. There will be a daily chance for showers and thunderstorms with the best chance closer to shore during the afternoon hours. && .FIRE WEATHER... Issued at 1235 PM CDT Fri Aug 7 2026 Hit or miss showers and thunderstorms will be possible each afternoon through the weekend. Widespread significant rainfall is not expected and this will likely allow the overall antecedent conditions to become drier with an increase in the KBDI. With low level Gulf moisture from mainly southerly winds, minimum afternoon relative humidity values are expected to range from 50 to 60 percent. && .LCH WATCHES/WARNINGS/ADVISORIES... LA...None.
