Trader consensus on Polymarket clusters around 68-71°F for Houston's highest temperature on April 5, reflecting National Weather Service guidance amid an approaching cold front from the west that promises clouds, showers, and reduced diurnal heating. The Euro model's early-morning frontal arrival supports cooler outcomes near 68-69°F by limiting daytime warming, while the GFS's later midday timing bolsters odds for 70-71°F or slightly higher before reinforcement. Precipitation probabilities near 50% and a flash flood watch through Sunday morning further cap peaks, overriding the area's recent warm pattern of 80s°F highs. New model runs and NWS updates expected within 24-48 hours could sharpen this spread, as small shifts in steering patterns tip the balance.
