**Numerical weather prediction models, including recent GFS and ECMWF runs, currently favor a maximum temperature in Warsaw on September 15 near 18–20°C under mostly cloudy skies with light westerly flow and limited diurnal heating.** This consensus reflects stable high pressure and modest warm advection that has kept recent daytime highs in the mid-to-upper teens Celsius, close to September climatological averages for the region. Minor model differences in cloud cover timing and boundary-layer mixing create the tight clustering of market-implied probabilities around 18–21°C, with lower odds on outliers reflecting the low likelihood of significant synoptic shifts in the next 48 hours. Updated model guidance and observational data from Warsaw Chopin Airport will refine the exact peak 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.
