Latest ECMWF and GFS ensemble forecasts, updated in the past 24 hours, project Warsaw's highest temperature on April 4 clustering tightly around 13-14°C near Chopin Airport—the market's resolution station—driving trader consensus with 35% implied probability for 14°C and 28% for 13°C. Differentiating factors include subtle model spread: ECMWF control runs lean slightly warmer under partly cloudy skies and weak westerly winds, while GFS ensembles show cooler biases from potential low-level cloud persistence or diurnally variable insolation. Early April climatology supports this range, with historical highs averaging 12-14°C amid transitional spring patterns. New 12Z model outputs today could sharpen guidance before official observations resolve the market.

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.
