Current forecast consensus from numerical weather models, including GFS runs, points to an overnight low near 12°C in Warsaw on September 3 due to clear to partly cloudy skies, light southwesterly winds, and radiative cooling after daytime highs around 21–24°C. This aligns with climatological norms for early September in the region, where minimum temperatures typically range 10–13°C absent strong advection. The 95.5% implied probability for 12°C reflects trader confidence in stable model agreement and limited short-term variability. A shift in cloud cover, stronger winds, or revised observational data from official stations could realistically push the recorded minimum to 13°C or higher, though such changes appear unlikely given current conditions.

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=epwa
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.
