Trader consensus on Polymarket reflects tight uncertainty in National Weather Service guidance and global model ensembles like GFS and ECMWF, which project Denver's April 5 high temperature in the mid-60s Fahrenheit range at Denver International Airport (KDEN). Recent 00Z runs show a building upper-level ridge over the Rockies promoting downslope warming and sunny skies after a cold snap with yesterday's high near 39°F, but model spread of 3-5°F stems from differing predictions on high cloud cover from an approaching shortwave trough and diurnal boundary layer heating efficiency. Normal April 5 highs sit at 60°F; key differentiators include wind shear mixing cold surface air and exact ridge axis placement, with new 12Z forecasts expected midday April 3 potentially clarifying the 64-65°F versus 66-67°F edge. Precipitation odds remain low at under 20%.
