105 FXUS64 KBRO 301055 AAA AFDBRO Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 555 AM CDT Mon Jun 30 2025 ...New AVIATION... .SHORT TERM... (Monday through Wednesday) Issued at 1033 PM CDT Sun Jun 29 2025 Tropical Depression Barry has made landfall in Eastern Mexico, 273 miles south of Brownsville. Its remnants are bringing showers and some thunder to the region tonight, and an increased swell is leaving a Moderate Risk of rip currents. These showers and coastal hazards are the only anticipated impacts to Deep South Texas from TD Barry. While flash flooding is not anticipated, PWAT values of 2.25" from the 00Z sounding indicate plenty of moisture available and may allow for heavy rain rates, which can lead to ponding. Showers are likely (70-80%) with thunderstorms possible today as moisture influx from Barry`s remnants work northward. The chance for showers and thunderstorms will continue through Wednesday, with rain chances beginning to decrease Monday night. Rain chances are moderate (50-60%) on Tuesday with thunderstorms possible, and low (10-20%) Wednesday. High moisture content lead to heavy rainfall within showers possible. High temperatures early this week start off below normal - highs in the 80s will not feel realized with this increase of moisture, leaving apparent temps in the 90s to around 100 by midweek. Seasonable low temperatures in the 70s provide little relief. At the local beaches, increased swell from TD Barry maintains a Moderate Risk of rip currents. && .LONG TERM... (Wednesday night through next Monday) Issued at 1033 PM CDT Sun Jun 29 2025 Chances of rain decrease from low (10-20%) to almost none through the long term period. While PoPs decrease through the week, temperatures are expected to increase as cloud cover clears and high pressure builds over the central US. A Moderate Heat Risk is possible late week with apparent temperatures climbing into the triple digits. && .AVIATION... (12Z TAFS) Issued at 551 AM CDT Mon Jun 30 2025 Minor adjustments made to the previous issuance of TAFs. A TEMPO has been retained for the possibility of convection and is based on the HRRR model. Breezy winds today will diminish around sunset. && .MARINE... Issued at 1033 PM CDT Sun Jun 29 2025 Moderate southeasterly winds will prevail over the period. Moderate seas brought by Tropical Depression Barry will decrease to slight by Tuesday, with generally favorable conditions for the remainder of the period. Moderate to high chance (50-80%) of rain and thunderstorms are possible through Tuesday, decreasing to low (10-20%) through Friday. Gusty winds and heavy downpours are possible in any showers, along with lightning in any thunderstorms, temporarily degrading marine conditions. && .PRELIMINARY POINT TEMPS/POPS...
