Latest NOAA ensemble forecasts and major models like GFS and ECMWF converge on a high temperature of 60-61°F for New York City on March 27, anchoring the 29% implied probability atop trader sentiment amid a mild ridge of high pressure over the Northeast. This edges out 58-59°F (20.5%) and 62-63°F (20.5%) due to subtle differences in simulated boundary layer mixing and afternoon cloud cover, with the GFS deterministic run peaking at 61°F while the Euro leans 1-2°F cooler. Historical March 27 averages hover near 52°F, but an anomalously warm early spring pattern—fueled by persistent southerly flow—supports these upper-50s to low-60s outcomes, though lingering frontal timing uncertainty tempers hotter bets below 5%. Traders eye the 00z model update for resolution shifts.

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.
