Recent forecasts from models like GFS and observations indicate Warsaw experienced clear to partly cloudy skies with light westerly winds under high pressure, promoting radiative cooling after daytime highs near 19–20°C. This setup positioned overnight lows around 11–13°C early on September 12, with some hourly data showing dips toward 10–11°C by late evening, aligning trader focus on the 10°C and 9°C outcomes. Stable synoptic conditions without incoming fronts or significant moisture have limited further cooling, while climatological September baselines near 12°C provide context for the narrow implied range. Updated model runs and real-time station reports through the evening will refine the final minimum before 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=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.
