**Current ensemble forecasts for Istanbul on September 21 show daytime highs near 25–27°C under mostly clear, high-pressure conditions, with nighttime lows centered around 17–19°C but carrying notable spread.** This uncertainty drives the near-even split between the ≤15°C and ≥25°C buckets, as traders weigh radiative cooling potential on calm, clear nights against residual warmth from daytime advection or light winds. Model differences in boundary-layer mixing and dew-point depression create the observed dispersion around typical mid-September minima of 16–17°C. Fresh ECMWF and GFS runs over the next 24–48 hours will likely tighten the range ahead of 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=LTFM
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.
