Latest ECMWF and GFS ensemble forecasts drive the neck-and-neck trader odds for Paris's highest temperature on March 24, with model means hovering at 17-18°C amid a mild Atlantic southerly flow and ridging high pressure. The 29.5% implied probability for 18°C edges out 17°C at 28.5% due to recent warming adjustments in ECMWF runs, while 19°C's 20.5% reflects upper-ensemble outliers from urban heat amplification and low cloud cover. Differentiating factors include model spread (15-20°C), verified by Météo-France observations, against March norms of 12-14°C highs; soil moisture deficits favor slight overperformance, though cold air advection risks cap extremes below 20°C. Traders eye tomorrow's 12Z 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 Charles de Gaulle Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/fr/paris/LFPG.
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.
