Current forecast models from sources including GFS and regional European guidance point to overnight lows in Paris on September 7 near 18–20°C, driven by persistent cloud cover and a moderating southwesterly flow that limits radiative cooling under partly to mostly cloudy skies. This setup favors the market’s tightly bunched leading outcomes around 18–19°C, as reduced clear-sky heat loss and mild advection keep minimum temperatures above seasonal averages of roughly 12°C. Model spreads arise mainly from small differences in timing of any scattered showers and boundary-layer mixing, which could nudge the exact low by 1–2°C; fresher runs or satellite updates on cloud trends will likely refine these probabilities ahead of 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.
