Official National Weather Service forecasts for Houston on September 28, 2026, indicate a high near 93°F under sunny to mostly sunny skies with light southeast winds, driven by persistent high pressure and clear conditions typical of late September. These patterns favor strong daytime heating without significant cloud cover or precipitation to moderate temperatures, consistent with recent climatological baselines around 89–92°F. Model consensus from NWS and other sources shows limited variability in the 92–94°F range, though minor shifts in steering winds or moisture could alter the exact peak. The market's emphasis on 90–91°F alongside elevated odds for 102°F+ reflects trader assessment of measurement thresholds at primary stations like IAH and potential for localized extremes amid overall warm, stable atmospheric conditions. Updated model runs and morning observations will provide the final data inputs before resolution.
