Trader consensus on Polymarket has locked in 82-83°F as the highest temperature in Houston on March 26, reflecting near-unanimous agreement from National Weather Service forecasts and ensemble model runs from GFS and ECMWF, which project a daytime high of 82-83°F under building high pressure aloft and light southerly winds advecting mild Gulf moisture. Recent 12- and 24-hour updates show minimal spread in guidance, with surface observations aligning to expected diurnal warming capped by mid-level subsidence. This positioning draws from historical March norms in Houston, where highs average 75-80°F but ridge dominance boosts readings into the low 80s. Realistic challenges include an unanticipated marine layer thickening or weak frontal trough stalling nearby, though current satellite and radiosonde data indicate low likelihood before resolution via official airport measurements.
