**Recent National Weather Service and model guidance point to a high temperature in the low-to-mid 90s for Houston on August 28, 2026, with afternoon showers and thunderstorms expected to limit peak heating.** Official forecasts from the NWS Houston/Galveston office show a high near 93–94 °F under mostly sunny skies early, followed by a 40 % chance of scattered showers and thunderstorms after midday as an upper-level impulse increases moisture and instability. Light northwest-to-east winds around 5 mph and high humidity (dew points in the low-to-mid 70s) will support heat indices near 104–105 °F, but cloud cover and any precipitation should prevent the extreme readings seen earlier in the week. This setup explains why the market’s two leading bins—94–95 °F (38 %) and 92–93 °F (27.5 %)—together capture roughly two-thirds of trader probability. These outcomes align closely with the consensus range in the latest model runs and area forecast matrices, which have trended slightly cooler for Friday after Thursday’s hotter conditions (upper 90s to near 100 °F). The modest 10.5 % probability on 96–97 °F reflects the remaining upside risk if storms remain suppressed or delayed, while probabilities drop sharply above 98 °F or below 90 °F given the expected steering pattern and climatological norms for late-August Houston. Key resolution factors include the official daily maximum at major reporting stations (e.g., Hobby or Intercontinental) and the timing/intensity of any convective activity. Updated NWS forecasts and short-range model guidance issued on the morning of the 28th will be the primary drivers of any late shifts in market-implied odds.
