Recent forecast models from the Russian Hydrometeorological Center and international ensembles show a high-pressure ridge directing warmer continental air toward Moscow, supporting a daily maximum near 26°C on May 17. This setup features light southerly winds, reduced cloud cover, and daytime heating that exceeds the mid-May climatological average of about 18°C at the VDNKh station. Trader consensus at 93.5% implied probability for 26°C reflects strong agreement across these runs, with minimal spread in boundary-layer mixing and radiation forecasts. Outcomes above 27°C carry only 5% combined odds due to limited potential for stronger subsidence or advection. A shift in short-term model guidance or unexpected increase in cloud cover could still alter the final peak before official resolution tonight.

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.
