Recent model consensus from sources like GFS and ECMWF points to overnight lows of 9–11°C in Warsaw on September 22 under northwest flow, scattered showers, and variable cloud cover that moderates radiative cooling. These conditions follow a cooler, showery pattern established on September 21, with surface winds of 10–15 km/h limiting temperature drops. The near-even market split between outcomes at or below 4°C and at or above 14°C reflects remaining uncertainty in exact minimum timing, precipitation duration, and model spread on boundary-layer moisture. Updated runs and local observations over the next 48 hours will refine resolution criteria for the daily low.

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.
