Trader consensus on Polymarket implies a 42.5% probability for Houston's highest temperature on April 7 to reach 67°F or below, driven by National Weather Service forecasts of a cold front arriving over the Easter weekend (April 5-6), ushering in cooler post-frontal air masses with northerly winds and scattered showers. Recent developments, including NWS updates on April 3 highlighting heaviest rain Saturday afternoon, have boosted cool outcomes as model ensembles like GFS show highs clustering in the upper 60s to low 70s, below the April 7 historical average of 77.5°F. A 25% implied chance for 86°F or higher reflects uncertainty in frontal stall or weakening, potentially allowing pre-frontal warmth to linger. New forecast runs expected daily from NWS Houston/Galveston could refine these probabilities amid inherent short-range variability.
