Recent model consensus points to overnight lows of 11–13°C in Warsaw on September 11, driven by a shift from warm southerly flow to lighter westerly winds and partial cloud cover after a front passes on the 10th. This setup permits moderate radiative cooling under clearer skies but limits deeper drops, consistent with September climatology where average minima reach about 10°C. Ensemble spreads and timing differences in cloud breaks or residual moisture explain the tight 49% split between sub-5°C and 15°C+ outcomes, with traders weighing the risk of under-forecasted clear, calm conditions versus lingering warmth. Fresh runs from ECMWF and ICON will refine the minimum 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=epwa
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.
