Ensemble forecasts from NOAA's GFS and ECMWF models drive the tight clustering of market-implied odds around 82-93°F for Houston's March 25 high temperature, reflecting a warm ridge amplifying southerly flow and above-normal heat advection amid low soil moisture from recent dry conditions. GFS ensembles skew toward 90-93°F with stronger subsidence, while ECMWF hints at 82-85°F via subtle shortwave phasing and mid-level clouds, differentiating the leaders; both diverge from the March climatological average of 76°F. Trader sentiment hinges on today's 12Z model updates, as phasing uncertainty keeps 17% probabilities even, with minimal support below 80°F absent a surprise front. Official measurement at Houston's George Bush Intercontinental Airport will resolve thresholds precisely.

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.
