Ensemble weather models like ECMWF and GFS drive the 52% implied probability for Warsaw's highest temperature on March 20 at 11°C, with recent runs converging on daytime peaks in the 10-12°C range amid a mild southwest airflow. Poland's IMGW meteorological service corroborates this, forecasting cloudy conditions with scattered showers limiting extremes, positioning 10°C (14.5%) and 12°C (11.8%) as strong contenders while downplaying outliers. Historical March 20 highs average 9°C, but an ongoing warm anomaly—verified by recent EUMETSAT satellite data—elevates these milder outcomes; traders eye tomorrow's 12Z model updates for potential shifts in convective activity.

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.
