Latest numerical weather prediction models, including runs from ECMWF and GFS, indicate Istanbul's daytime high on September 18 will likely peak near 24°C under partly cloudy skies with light northeasterly flow. These conditions, combined with recent surface observations in the low 20s°C and typical mid-September climatology, limit strong warming while keeping values above seasonal averages. Minor ensemble spread around the precise maximum, along with slight variations in cloud cover and timing of any showers, supports the market's heavy weighting toward 23°C and 24°C resolutions. Updated model guidance and official Turkish Meteorological Service briefings expected overnight will provide the final inputs before the daily high is recorded.

The resolution source for this market will be information from NOAA, specifically the highest 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.
