Trader consensus on Polymarket reflects tight uncertainty in National Weather Service forecasts for Houston's April 17 high temperature, with 84-85°F (40.5%) edging 82-83°F (32.5%) amid model spread from GFS and ECMWF ensembles. Latest NWS guidance calls for partly sunny conditions with highs near 86°F under south-southeasterly winds of 10-20 knots promoting diurnal heating, but morning clouds and 65% diurnal cloud cover risk could cap peaks 2-3°F lower by limiting solar insolation. Upper-80s potential hinges on rapid clearing and dry boundary layer stability, while subtle pre-frontal moisture might favor mid-80s; new HRRR and NAM runs expected midday could sharpen resolution before evening peak heating. Historical April averages hover near 79°F, underscoring above-normal warmth from persistent high pressure.
