Recent forecasts from the Finnish Meteorological Institute and European models indicate a northwest airflow and mostly clear skies overnight into September 6, favoring radiative cooling and supporting trader focus on lows near 7–9 °C. With average September minima around 10–11 °C and record lows near 3 °C, the closely matched probabilities reflect uncertainty in exact overnight minimums driven by wind speed variations and any residual cloud cover. High-pressure dominance limits precipitation but amplifies diurnal temperature swings, while model consensus on 15–16 °C daytime highs narrows the expected drop. Updated runs from FMI and ECMWF over the next 12–24 hours will likely refine these ranges ahead of market 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=efhk
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.
