FXUS64 KHGX 281753 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1253 PM CDT Thu May 28 2026 ...New DISCUSSION, MARINE... .KEY MESSAGES... - Patches/areas of Fog expected late tonight into Friday morning, possibly dense in some spots. - Drier but warmer conditions anticipated through Sunday. Make sure to be prepared for the warmer temperatures if you plan to work or spend time outdoors. - Daily chance for showers and thunderstorms expected next week. && .DISCUSSION... Issued at 1135 AM CDT Thu May 28 2026 After several days of having showers and thunderstorms develop or move through Southeast TX, we are going to have a bit a break in the next few days as a mid to upper level ridge sets up over Texas. For the rest of today, expect mostly sunny to partly cloudy skies along with light variable winds. There is a very slight chance for a storm or two to develop mainly over areas near the Brazos Valley this afternoon/evening as a mid level disturbance and vort max move overhead...but the high pressure to our west could limit their development. Otherwise, mostly tranquil conditions are expected with high temperatures in the upper 80s inland and the mid 80s along the coast. Conditions will remain benign Friday into the upcoming weekend, but aside from our limited chances for showers and storms, we will need to monitor the heat conditions and impacts as the local temperatures rise into the 90s. I honestly don't know what is worse, the constant influx of storms or the notoriously unforgiving feeling of the Houston summer heat :/. As for our expected temperatures, we are looking at highs peaking in the lower 90s Friday into Monday for most of the inland portions and the mid to upper 80s along the coast. Unfortunately, the overnight to early morning lows will go from the lower 70s Friday night into the lower to mid 70s on Saturday and Sunday night. Along the coasts, the lows could range closer to the upper 70s. Heat indices will ramp up as well and are expected to reach the upper 90s Friday into early next week, with some isolated spots possibly reaching the lower 100s. It's a good reminder to be proactive with heat safety, especially since we are transitioning into summertime temperatures. Daily chance for showers and thunderstorms are expected to return to Southeast TX early next week as the ridge weakens, surface moisture increases (PWs of 1.7-2.1"), and several upper level disturbances move over TX. So far, the best opportunities for development are during the afternoon and evening hours as diurnal heating and instability peaks. One good news is that we might be looking at high temperatures falling back into the upper 80s range sometime mid-week. Cotto && .AVIATION...
