**Forecast models indicate Moscow's overnight low on September 19 will likely fall in the 9–12°C range, creating near-even market odds between a sub-4°C minimum and one at or above 13°C.** Southwesterly flow and variable cloud cover are the dominant influences, limiting nocturnal radiative cooling while preventing strong cold advection. Ensemble guidance shows modest spread in boundary-layer mixing and shower timing, which can shift the daily minimum by several degrees. Historical climatology places the typical September 19 low near 7–8°C, so current projections sit slightly above average but remain sensitive to small changes in humidity, wind, and cloud persistence. New model cycles and updated observations over the next 48 hours will be the key catalysts for any odds movement before resolution.

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.
