Recent model consensus from ECMWF, GFS, and regional sources points to a high of 15–16 °C in Warsaw on September 23 under building high pressure (around 1020 hPa) and northwesterly flow, which explains the tight clustering of market-implied odds around those values. Persistent cool maritime air, limited daytime heating from partial cloud cover, and modest wind mixing keep maxima from climbing higher despite clearing skies. Small differences among leading outcomes hinge on exact cloud timing, boundary-layer mixing, and any weak frontal passage—variables that produce the observed 1–2 °C spread in ensemble guidance. With resolution imminent, traders are weighting the latest short-range runs and station observations heavily.

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.
