Trader consensus on Polymarket assigns a 100% implied probability to a highest temperature of 38-39°F at Buckley Space Force Base (KBKF), Denver's official station for this market, confirmed by National Weather Service daily climate reports following an unprecedented late-spring snowstorm on May 5-6. Heavy snowfall—over 5 inches at nearby sites—combined with persistent cloud cover, light snow/mist, and northerly winds from a deep cold air mass suppressed daytime heating, yielding one of May 6's lowest highs near the record low maximum of 35°F set in 1978. Model ensembles like GFS and NAM had anticipated this chill pre-event, with minimal diurnal warming under overcast skies. Resolution is near-certain barring rare observational revisions by NOAA.
