Ensemble forecast models from NOAA and ECMWF drive trader consensus toward highs of 80-85°F in Dallas on March 27, with GFS leaning 82°F and ECMWF slightly warmer at 84-85°F, creating tight odds across these bins. A building upper-level ridge and persistent southerly winds from the Gulf promote warm air advection and ample insolation, pushing temperatures 10-15°F above the late-March climatological average of 72°F. Differentiating factors include model spread on diurnal boundary layer mixing—stronger vertical mixing favors 84-85°F peaks—versus potential mid-afternoon cirrus clouds or light shear capping at 80-81°F. Historical data shows similar setups yielding 82°F medians, but urban heat island effects in Dallas add 2-3°F upside variability. Traders eye 18z updates for resolution clarity.

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 Dallas Love Field Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/tx/dallas/KDAL.
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.
