FXUS64 KHGX 101025 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 525 AM CDT Wed Jun 10 2026 ...New AVIATION... .KEY MESSAGES... - Increasing heat risk with "feels-like" temperatures around 97-107 degrees (36-42 Celsius). - Risk of Rip currents across Gulf-facing beaches throughout the week. - Isolated/scattered showers and thunderstorm chances daily, mostly during the afternoon hours. Chances will increase Sunday into next week. && .DISCUSSION... Issued at 1101 PM CDT Tue Jun 9 2026 Subtropical ridging is anticipated to keep warn, humid weather in place throughout the remainder of the week. Onshore winds should remain firmly remain in place due to a Bermuda high off the eastern sea board. Midlevel heights are forecast to be around 590-593 dam, above the 90th climatological percentile for this time of the year. NAEFS has indicated that 200mb mean geopotential heights will also be strongest around the weekend. Subsidence should largely inhibit storm development, though ample PWs of 1.4-2.3 inches and modest afternoon heating should still allow for isolated daily showers, especially during the afternoon along the sea breeze, with a thunderstorm or two as well. Highs are forecasted to reach the upper 80s to mid 90s (31-36 Celsius) with lows in the 70s to lower 80s (21-27 Celsius). Even with mixing, afternoon dewpoints are still anticipated to remain in the 70s (20-26 Celsius) each day, resulting in very humid weather. Max heat indicies are forecasted to reach 97-107 degrees (36-42 Celsius) during the afternoon. WBGT Heat stress is forecasted to be high with each day as well. Sensitive groups or those not acclimated to the summer like weather of Houston will be at a greater risk of experiencing heat illness. Cannot rule out the potential for heat advisories, especially this weekend. If you plan to spend time outdoors, make sure to drink plenty of water to stay hydrated. If you plan on heading to the beach to beat this heat, make sure to watch out for rip currents! We should see the weather pattern change heading into next week, as a mid/upper level trough digs into the Plains. This feature should shove the subtropical ridge further south, lowering heights over SE Texas. In addition, this feature is also progged to push a cold front towards SE Texas. Model guidance has this cold front reaching the Brazos Valley early Tuesday morning. Scattered showers/storms will be possible as the front pushes southward towards the coast. As we head deeper into summer, the possibility of fronts reaching/pushing through SE Texas generally declines, thus there is still potential to see some changes in the fronts positioning these next several days. Regardless, declining temperatures/heat stress and rising rain chances are anticipated for the first half of next week. 03 && .AVIATION... (12Z TAF Issuance) Issued at 525 AM CDT Wed Jun 10 2026 MVFR ceilings prevail at a few of the northern terminals early this morning with VFR ceilings elsewhere. MVFR ceilings may briefly develop further south through 15Z before lifting back to VFR for the rest of the day. Southeasterly winds will be in the 8-12 kt range with gusts up to 20 kt at times through the afternoon. Isolated to widely scattered streamer showers are moving through the area early this morning. Additional isolated showers with potential for an isolated thunderstorm or two will be possible in the late morning to afternoon hours. These have been covered with PROB30's in this TAF package. Rain activity dissipates after 00Z with MVFR ceilings developing again at least for some of the Houston metro terminals and the northern terminals overnight into Thursday morning. Some isolated pockets of patchy fog with reduced visibilities cannot be ruled out either. Batiste && .MARINE... Issued at 1101 PM CDT Tue Jun 9 2026 Light to occasionally moderate onshore winds are expected throughout the rest of the work week with seas of 2 to 5 feet. Caution flags may be warranted at times, especially this weekend as seas near 6 to 7 feet offshore. Isolated showers and thunderstorms will be possible each day with rain chances rising over the weekend into early next week. There will also be a moderate to high risk of rip currents across Gulf facing beaches through early next week. 03 && .PRELIMINARY POINT TEMPS/POPS...
