Latest National Weather Service guidance and ensemble forecast models, including GFS and ECMWF, project Denver's high temperature on April 13 at 68-70°F—well above the 1991-2020 normal of 61°F—fueling the 98.2% market-implied odds for 64°F or higher as traders price in strong consensus on mild spring conditions. This positioning stems from a persistent upper-level ridge following record highs of 81°F on April 9 and 80°F on April 10, with NOAA's April outlook favoring above-normal temperatures amid weak El Niño influences. Realistic challenges include an approaching low-pressure system from the southwest, potentially delivering widespread clouds and showers (PoP 80-100% in some guidance), which could suppress daytime heating if precipitation arrives early; however, model clusters show low risk of sub-64°F outcomes. Watch 00Z model runs Sunday evening for refinements ahead of resolution.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Buckley Space Force Base Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/co/aurora/KBKF.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
