This market will resolve to the temperature range that contains the highest temperature recorded at the LaGuardia Airport Station in degrees Fahrenheit on 31 Mar '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 LaGuardia Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/us/ny/new-york-city/KLGA. 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.The National Weather Service's latest guidance for New York City forecasts a high near 73°F at Central Park on March 31, anchoring trader sentiment with 74°F or higher leading at 45.5% market-implied probability, closely trailed by 72-73°F at 22% and 70-71°F at 19.5%. This reflects a potent upper-level ridge promoting warm air advection from the subtropical southeast, with GFS and ECMWF ensembles over the past 24 hours converging on above-normal readings amid sunny skies and light winds. Ensemble spreads indicate modest uncertainty in peak heating, but recent runs have trended slightly warmer; updated model output and NWS bulletins due this evening could refine these odds further. March climatology averages 52°F, highlighting the setup's anomaly.
