**Current forecast consensus from the Finnish Meteorological Institute and models like Foreca points to overnight lows near 13–15°C on September 9, keeping the daily minimum well above the 9°C threshold favored by traders at 49.5% implied probability.** This positioning reflects model agreement on mild southwesterly flow and limited radiational cooling under mostly cloudy conditions with light rain chances, consistent with early-September climatology where average lows hover around 10°C. Recent observations of slightly cooler nights earlier in the week may contribute to the elevated odds on colder outcomes, while the 29.5% on 19°C or higher captures tail-risk warming scenarios if high pressure builds faster than expected. Upcoming model runs and FMI updates over the next 24–48 hours 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=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.
