Trader consensus on Polymarket reflects National Weather Service guidance indicating a cold front arriving in southeast Texas Saturday evening, April 18, ushering cooler post-frontal air masses, increased cloudiness, and possible lingering showers into Sunday, April 19, suppressing Houston's high temperature to the low-mid 70s°F range. The razor-thin margin between 70-71°F (29.5% implied probability) and 72-73°F (28.5%) stems from ensemble model discrepancies in GFS and ECMWF runs, particularly frontal timing, boundary layer recovery, and cloud cover persistence, which dictate diurnal heating potential. Northerly winds post-front and marginal excessive rainfall risk along I-10 further cap warming; watch NWS updates Saturday for refined short-range forecasts clarifying the peak temperature at official observing sites like IAH.

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 19 Apr '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.
