Ensemble forecasts from ECMWF and GFS models are the primary drivers behind trader consensus for Warsaw's March 27 high temperature, with probabilities tightly clustered around 11-13°C reflecting mild southerly airflow and above-average warmth for late March. The ECMWF operational run projects a peak near 11°C under partly cloudy skies, while GFS ensembles lean slightly warmer at 12-13°C due to stronger ridging over Central Europe; this model divergence explains the razor-thin spread in market-implied odds. Historical data shows March 27 averages around 9-10°C, but current positive temperature anomalies (+2-3°C) from a weakening polar vortex bolster higher outcomes, though shortwave trough risks could cap peaks at 10°C or below. Traders eye tomorrow's 12Z model updates for resolution shifts.

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.
