Official meteorological data from Moscow stations, including Vnukovo and VDNKh references monitored by Roshydromet, confirmed a daily maximum temperature of 23°C on May 15 under a high-pressure ridge with southerly winds and intermittent cloud cover that permitted sufficient solar insolation for modest warming above the mid-May climatological average of 19°C. Ensemble forecasts from ECMWF and GFS converged on this outcome days prior, reflecting limited convective inhibition and no significant cold-air advection. Trader consensus at near-100% probability for 23°C aligns with these verified observations, though minor adjustments could arise only from final post-processing of hourly readings or station-specific calibration differences.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column on the specified date once information is finalized for all hours on that date, available here: https://www.weather.gov/wrh/timeseries?site=UUWW
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve to "Yes" until data for this date has been finalized.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). 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.
