Recent forecasts from multiple models, including GFS and ECMWF runs updated September 17, indicate an overnight low in Warsaw near 10–12 °C on September 18 under partly to mostly cloudy skies and light southwesterly flow. A cold front that crossed the region on the 17th delivered rain and a sharp drop from prior daytime peaks above 20 °C, advecting cooler maritime air that now moderates minimum temperatures. Radiative cooling overnight will be limited by cloud cover and dew points near 9–10 °C, reducing the likelihood of readings at or below 8 °C while also capping any rebound toward 15 °C or higher. Trader emphasis on the 8 °C outcome at 43 % implied probability appears to reflect residual model spread in boundary-layer mixing and local urban heat-island effects rather than current consensus guidance.

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.
