Trader consensus on Polymarket reflects high uncertainty in forecast ensembles for Houston's highest temperature on March 29, with models clustering outcomes between 78-83°F amid a building upper-level ridge ushering warm southerly flow into southeast Texas. The National Weather Service's latest guidance points to a high near 82°F under mostly sunny skies with light winds, but ensemble spreads highlight risks of sea-breeze timing or thin high clouds capping peak heating lower (78-79°F) or allowing slightly more insolation for 84°F+. Recent 12z GFS and ECMWF runs diverged modestly after yesterday's cooler bias correction, while climatological late-March averages hover around 78°F. Key differentiator: afternoon boundary layer mixing efficiency. Watch evening NWS updates and hourly obs for resolution clarity.
