Official National Weather Service observations at Houston's William P. Hobby Airport (KHOU)—the designated resolution station—confirm the highest temperature reached 85°F at 3:04 PM CDT on April 16, 2026, locking in 100% market-implied probability for the 84-85°F outcome as traders aggregated real-time data from Wunderground. This matched pre-event NOAA forecast model consensus for low-to-mid 80s highs under a high-pressure ridge, partly cloudy skies, southerly winds of 3-20 mph promoting warm air advection, and dew points in the 60s°F enabling efficient daytime heating without excessive humidity. Slightly above the April climatological average of 79°F, the reading reflects typical spring warming patterns. Realistic challenges would require rare quality-controlled data revisions by NWS, such as sensor recalibrations, though preliminary reports seldom change for non-extreme events; next daily climate summaries expected soon.

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 William P. Hobby Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/tx/houston/KHOU.
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.
