Divergent ensemble forecasts from the GFS and ECMWF models drive the closely matched market-implied probabilities for Houston's highest temperature at Bush Intercontinental Airport on April 4, with spreads of 10–15°F around the climatological average of 78°F reflecting uncertainty in upper-level ridge persistence over Texas versus the timing of a weak cold front. The 90°F or higher outcome leads at 21.5% due to hotter GFS runs emphasizing prolonged southerly warm advection and sunny skies, while clustered 70s–80s bins at 17–18% capture ECMWF's cooler tilt from increased cloud cover or frontal influences. National Weather Service extended outlooks point to near-normal spring conditions following March's warmth, but inherent model discrepancies sustain broad trader consensus. New 00Z/12Z runs and NWS updates through April 2 will likely refine these odds.
