Recent National Weather Service and model guidance points to a shift toward thunderstorms and increased cloud cover over North Texas on June 4, which is moderating expected daytime highs into the mid-80s and differentiating the closely bunched 84–85 °F and 86–89 °F outcomes. This cooling follows several days of sunnier, hotter conditions early in the month and aligns with climatological patterns where early-June instability often suppresses peak temperatures below the seasonal 88–93 °F average. Traders are weighting the latest ensemble runs showing limited sunshine and possible heavy rain that would cap heating, while still assigning meaningful probability to 88–91 °F if storms remain scattered or delayed. Updated short-range model guidance and local observations over the next 48 hours will likely refine these probabilities ahead of market resolution.
