Latest National Weather Service guidance and forecast ensembles from NOAA's Global Forecast System (GFS) and European Centre for Medium-Range Weather Forecasts (ECMWF) project Austin's highest temperature on March 27 clustering at 86-89°F, driving trader consensus with 35.5% implied probability on 88-89°F and 26% on 86-87°F. A persistent upper-level ridge over the central U.S. promotes warm air advection from the south, subsidence inhibiting clouds, and light southerly winds maximizing daytime heating under sunny skies, pushing readings well above the climatological March average of 74°F. Differentiating factors include model spread on afternoon cloud development and exact ridge amplitude—stronger ridging could nudge toward 90°F+, while subtle shear might cap at 86°F. New 12z model runs expected today will refine these uncertainties ahead of the event.

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 Austin-Bergstrom International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/tx/austin/KAUS.
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.
