Latest numerical weather prediction models from major centers indicate a daytime maximum near 20–21°C in Warsaw on September 18, under mostly cloudy skies with only light rain possible and moderate southerly flow. This follows a brief warm spell peaking at 24°C on September 16 before a cooling trend associated with a passing frontal system on the 17th. Ensemble spreads remain modest but allow for minor deviations tied to cloud cover timing and boundary-layer mixing, consistent with typical mid-September variability around the 18–20°C climatological range. Updated high-resolution runs and observational data in the next 24–48 hours will narrow the precise peak value ahead of market resolution.

The resolution source for this market will be information from NOAA, specifically the highest 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.
