Latest ECMWF and GFS ensemble forecasts have converged on Warsaw highs of 27-28°C on May 4 under a persistent high-pressure ridge over Central Europe, delivering subsidence warming, clear skies, and southerly winds advecting mild continental air—well above the climatological early-May average of 19°C from IMGW and NOAA baselines. This setup, building since May 2's observed 15-26°C range, positions 29°C or higher at 50.5% implied probability, reflecting GFS outliers favoring enhanced surface heating, while ECMWF's cooler ~25°C tilt bolsters 26-28°C outcomes near 35-36%. Model spread highlights uncertainty in cloud cover and exact ridge strength; IMGW updates and new runs due by May 3 could shift trader consensus as resolution nears.

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.
