Official forecasts from Russia's Hydrometeorological Center and supporting model runs indicate a nighttime minimum of 6°C in Moscow on September 13 under mostly clear to partly cloudy skies, light westerly winds of 4-9 m/s, and stable high pressure near 750 mmHg that favors radiative cooling. This aligns with observed overnight readings approaching 47-49°F (roughly 8°C) early in the period, with daytime highs reaching 17-19°C before the drop. Trader consensus at 99% on 6°C reflects the tight clustering of GFS and local guidance with minimal spread, consistent with typical early-September climatology for the region. A sudden increase in cloud cover or a shift to stronger winds could limit cooling and push the low above 6°C, though current conditions show low probability of such changes before midnight.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=UUWW
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
