Recent forecasts from multiple models, including ECMWF and GFS runs, indicate an overnight low near 17–18°C for Istanbul on September 21 under mostly clear to partly cloudy skies with light northeast winds. This setup favors moderate radiative cooling, yet the near-even market split between a 15°C-or-below outcome and 25°C-or-higher reflects substantial uncertainty in boundary-layer conditions. Key variables include exact cloud cover timing, which can trap heat and raise minima by several degrees, and any late shifts in wind or advection from the Black Sea. Historical September variability around 16–19°C lows adds context, while the next model update cycle and real-time station observations tonight will likely refine the range before 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.
