Recent forecasts from GFS and other models indicate a high-pressure ridge over northern France will deliver clear to partly cloudy skies and light northeast winds overnight into September 21, favoring radiative cooling and supporting a minimum near 11–12 °C in central Paris. This aligns with the climatological average low of 11 °C for the date and recent observations of 12–13 °C lows under similar anticyclonic conditions. Traders assign the highest probabilities to 10 °C and 11 °C because small differences in boundary-layer moisture, exact wind speed, or urban heat-island effects could shift the overnight low by 1–2 °C, while the 26.5 % chance attached to 9 °C or below reflects the tail risk if clearer skies and drier air enhance cooling beyond current model consensus. No major frontal systems or precipitation are expected to moderate temperatures before dawn.

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.
