Recent forecasts from the Finnish Meteorological Institute and ensemble models indicate a stable late-summer pattern over southern Finland, with light southerly to southeasterly winds and increasing cloud cover expected to moderate overnight radiative cooling on August 28. This setup favors minimum temperatures clustering near 13–14 °C, as dew points hover around 12–14 °C and limited clear-sky periods prevent sharper drops. Model consensus shows only modest spread in boundary-layer mixing and wind speeds, explaining the tight market-implied probabilities between these two outcomes while lower probabilities for 12 °C or below reflect the reduced likelihood of stronger northerly advection or clear, calm conditions that would enhance cooling. Updated runs through the weekend will clarify any shifts from incoming Atlantic moisture.

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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
