**Trader consensus centers on a 9–11°C overnight low for Warsaw on September 7, driven by high-pressure ridging and light winds favoring radiative cooling under mostly clear to partly cloudy skies.** Official and ensemble forecasts (ECMWF, GFS, ICON) show a stable post-frontal air mass with dew points near 10°C and minimal cloud cover after midnight, allowing surface temperatures to drop efficiently. Model spread arises mainly from subtle differences in predicted wind speeds (2–4 m/s) and residual high-cloud timing, which can shift the minimum by 1–2°C. Historical September climatology for Warsaw supports this range, with typical early-month minima near 11–13°C under similar synoptic patterns. Upcoming 00Z/12Z model runs and any late-day convective debris will be the key near-term variables traders are monitoring.

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.
