The National Weather Service's latest guidance for Houston projects a high temperature of 84-87°F inland on May 5, fueled by south winds of 5-15 mph ushering warm, moist Gulf air amid partly to mostly cloudy skies and isolated shower chances. Recent model ensembles, including high-resolution runs updated within the last 24 hours, show consensus peaks near 86°F during afternoon hours, far exceeding the 78°F market threshold and aligning with early May climatological norms averaging 85°F. This drives the 100% trader-implied probability for 78°F or higher, backed by morning observations already in the mid-70s°F. Only an unforeseen surge in thunderstorm coverage or wind shift could suppress highs below 78°F, though current outlooks deem this unlikely; track NOAA hourly data and 2 p.m. CDT updates for confirmation.

This market will resolve to the temperature range that contains the highest temperature recorded at the William P. Hobby Airport Station in degrees Fahrenheit on 5 May '26.
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.
