Trader consensus heavily favors a Dallas high of 90-91°F on March 21, driven by converging NOAA GFS and ECMWF ensemble forecasts predicting sustained upper-level ridging over Texas, clear skies, and light southerly winds fueling adiabatic warming to that narrow range. Official model guidance from the National Weather Service aligns precisely, with initialized soundings showing near-record potential under persistent high pressure, well above the March climatological average of 68°F. This positioning reflects low model spread and historical accuracy for such synoptic patterns. Realistic challenges include an unanticipated shortwave trough introducing clouds or a nocturnal cold front surge, though current 500-mb charts show slim odds of disruption before peak heating.

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.
