Recent GFS and regional model runs indicate a southerly flow will deliver Moscow's September 21 daytime high near 19°C, with scattered showers possible under increasing cloud cover. This setup supports the market's tight clustering around 17–20°C outcomes, as modest differences in precipitation timing or wind strength can shift the daily maximum by 1–2°C. Southerly advection contrasts with typical mid-September climatology of 15–18°C highs, while model spread in cloud and rain forecasts introduces the primary uncertainty. Official updates from the Hydrometeorological Center and refined model guidance over the next 48 hours will clarify whether readings settle at 19°C or edge toward 20°C.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Vnukovo International Airport in degrees Celsius on 21 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest 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.Recent GFS and regional model runs indicate a southerly flow will deliver Moscow's September 21 daytime high near 19°C, with scattered showers possible under increasing cloud cover.
