Latest Météo-France guidance and ECMWF/GFS ensemble forecasts project a nocturnal minimum temperature of 4–7°C at Paris-Le Bourget Airport on May 15, driving trader consensus toward outcomes clustered around 3–6°C with 6°C leading at 25.5% implied probability. This cool bias stems from a persistent low-pressure trough ushering moist northerly airflow, fostering overcast skies and showers that limit daytime heating to 15–16°C highs and curb radiational cooling overnight, well below May climatological norms of 9–10°C. Differentiating factors include model spread—some ensemble members forecast sharper drops to 3°C under partial clearing, while others hold steadier near 7°C amid continuous cloud—forcing tight odds amid inherent short-range uncertainty. New 12Z runs from NOAA and ECMWF tomorrow will sharpen resolution criteria ahead of the early-morning low.

The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day by the Forecast for the Paris-Le Bourget Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/fr/bonneuil-en-france/LFPB.
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.
