National Weather Service observations at Houston's Intercontinental (IAH) and Hobby (KHOU) airports currently show temperatures reaching 89°F under mostly clear to partly cloudy skies and light southerly winds, already exceeding the 86°F threshold and supporting the market's unanimous trader consensus on 86°F or higher as the day's high. This aligns with official forecasts projecting a peak near 87°F amid high pressure dominance, above the May 10 climatological normal of 85°F. Model consensus reflects ample solar heating with minimal cloud interference so far. Realistic challenges include unexpected intensification of late-afternoon thunderstorms ahead of an approaching cold front capping temperatures below 86°F, though low rain chances (slight) and current upward trends render this unlikely; final NWS daily summary expected post-midnight.
