Recent model consensus from ECMWF and GFS indicates Istanbul's overnight low on September 21 will likely settle in the 17–19°C range under persistent high pressure and light northeast winds that limit radiative cooling. Clear to partly cloudy skies overnight allow some heat loss, yet the mild maritime air mass and dew points near 16°C prevent sharper drops below 16°C. Traders balancing the near-even odds between sub-15°C and 25°C+ outcomes appear focused on the narrow window for model shifts in wind direction or cloud cover ahead of the final observation period. Updated runs overnight and early morning local time will clarify whether any late steering changes alter the minimum.

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.
