Current National Weather Service and private model guidance for Houston on June 22 points to afternoon highs of 90–92°F under a warm, humid airmass with only slight chances of scattered thunderstorms. Typical June climatology at Bush Intercontinental shows a 92°F normal high, so the market’s tight clustering around 90–93°F reflects expectations of modest daytime heating tempered by possible early convection or increased cloud cover that limits peak insolation. Differentiation between the 90–91°F and 92–93°F bins hinges on the precise timing and coverage of storms, boundary-layer moisture, and any late-day clearing, all of which forecasters will refine with the next model runs and local observations before the daily maximum is recorded.
