Recent National Weather Service and Global Forecast System model runs point to a daytime maximum in the low to mid-80s across New York City on May 18, supported by southerly flow advecting warmer air masses while partly cloudy skies moderate solar heating and limit strong convective instability. Traders closely weight the 84–85°F, 82–83°F, and 80–81°F bins because small variations in afternoon boundary-layer moisture, cloud cover timing, and vertical mixing can shift the peak by a degree or two before official observations from Central Park and LaGuardia are finalized. This setup reflects typical early-season variability, with model consensus still evolving ahead of tomorrow’s verification.

This market will resolve to the temperature range that contains the highest temperature recorded at the LaGuardia Airport Station in degrees Fahrenheit on 18 May '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.Recent National Weather Service and Global Forecast System model runs point to a daytime maximum in the low to mid-80s across New York City on May 18, supported by southerly flow advecting warmer air masses while partly cloudy skies moderate solar heating and limit strong convective instability. Traders closely weight the 84–85°F, 82–83°F, and 80–81°F bins because small variations in afternoon boundary-layer moisture, cloud cover timing, and vertical mixing can shift the peak by a degree or two before official observations from Central Park and LaGuardia are finalized.
