Latest ensemble forecasts from ECMWF and GFS models show strong agreement on a Warsaw high temperature around 9°C on March 26, driving trader consensus with 37.5% implied probability there, closely trailed by 10°C (27.5%) and 8°C (25%). Persistent northerly airflow behind a recent cold front has cooled the region, with yesterday's observations near 7°C and limited diurnal warming expected due to cloudy conditions and light winds. Differentiating factors include model spread in boundary layer mixing—GFS runs slightly warmer with clearer skies, while ECMWF emphasizes overcast persistence—against March climatological averages of 8–9°C. New 00Z/12Z forecast updates tonight could refine this tight race before resolution via official IMGW measurements at Warsaw Chopin Airport.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Warsaw Chopin Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/pl/warsaw/EPWA.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
