035 FXUS64 KBRO 090317 AFDBRO Area Forecast Discussion National Weather Service Brownsville TX 1017 PM CDT Fri Aug 8 2025 ...New DISCUSSION, MARINE... .DISCUSSION... Issued at 1015 PM CDT Fri Aug 8 2025 Mid-level high pressure over the Desert Southwest and across the Southeastern US into the eastern Gulf will continue into next week. At the same time troughing and along the lower Texas coast will allow daily chances of showers and thunderstorms (20-35%), mainly along the sea breeze through Wednesday. Will see lesser chances (10% or less) of precipitation as we head towards the end of next week as mid level ridging spreads westward into Deep South Texas. Near to slightly above normal temps will continue into next week, with heat indices of 105 to 110 degrees each day. A few locations, especially across the inland coastal counties, may briefly have heat indices exceed 110 degrees especially as we head into mid to late week. The timeframe and coverage remains below Heat Advisory criteria but can not rule out the possibility of a Heat Advisory being needed Wednesday, Thursday and/or Friday. At the very least, SPSs will likely be needed. Heat risk will remain Moderate (level 2 of 4) to Major (level 3 of 4) every day. && .AVIATION...
