Latest ensemble forecasts from global models point to an overnight minimum in Paris on September 7 between 18–20 °C, driven by southwesterly flow advecting milder maritime air and increasing mid-level cloud cover that suppresses radiative cooling. Differences among leading outcomes hinge on precise cloud timing and any light showers: thicker, persistent stratus favors readings near 20 °C by trapping heat, while partial clearing or delayed precipitation could allow brief cooling toward 18 °C. Current conditions remain warmer than the long-term September average low of roughly 12 °C. Updated ECMWF and GFS runs overnight will provide the final guidance before resolution.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=lfpb
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
