Trader consensus has locked in 36-37°F as the highest temperature in New York City on March 18, driven by official National Weather Service observations at Central Park recording a high of 37°F amid persistent cold snaps from Arctic air masses. Supporting evidence includes aligned GFS and ECMWF model runs forecasting daytime highs in the mid-30s under partly cloudy skies with light winds, consistent with March climatology where NYC averages 47°F but often dips lower during late-winter outbreaks. This positioning reflects verified measurements from automated stations, minimizing uncertainty. Realistic challenges would require a post hoc data revision from NOAA—highly improbable given standardized quality controls—or an unreported microclimate spike, both with near-zero odds.

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.
