Recent forecast consensus from global models, including GFS outputs, indicates a daytime high of 27–28°C in Paris on September 14 under partly cloudy skies, light northwesterly winds, and stable high pressure. These conditions favor moderate diurnal warming above the 1991–2020 average high of 21.7°C, driving the 28°C outcome to 52% implied probability and 27°C to 28%. Limited precipitation chances and clear evening trends reduce cooling, while minor model spread keeps 29°C as a plausible outlier at 14.5%. Updated runs ahead of resolution will clarify any last adjustments from steering patterns or cloud evolution.

The resolution source for this market will be information from NOAA, specifically the highest 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.
