Latest forecast models indicate a minimum temperature of 11–13°C in Warsaw on September 16 under mostly clear skies and southerly winds, aligning with climatological norms for mid-September. This consensus from sources such as GFS and local analyses drives elevated implied probabilities for the 9–15°C range, as recent model runs show limited overnight cooling potential amid stable high pressure. The leading 16°C-or-higher outcome at 49% reflects residual uncertainty in boundary-layer mixing and any last-minute warm advection, while the low 8% probability for 6°C or below underscores the unlikelihood of strong radiational cooling or northerly shifts. Updated model guidance expected within 24 hours could further refine these market-implied odds.

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.
