Recent forecasts from multiple models, including GFS and ECMWF integrations, indicate a frontal passage over Warsaw on September 17 that will limit daytime heating through increased cloud cover and showers, capping highs near 19°C. This follows warmer, sunnier conditions on the 16th, when southerly flow supported peaks around 23–24°C. Precipitation and reduced insolation are key differentiators among 17–20°C outcomes, as even modest rain timing or intensity shifts can alter surface energy balance by 1–2°C. Ensemble spreads show moderate uncertainty in exact frontal timing and moisture, keeping probabilities clustered across the 16–19°C range while rendering 22°C+ or sub-15°C scenarios unlikely under current synoptic patterns.

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.
