Recent precipitation and northerly winds have cooled Istanbul, with models showing overnight lows for September 24 ranging from the low teens to mid-teens Celsius depending on cloud cover and radiative cooling rates. Clear skies after Wednesday's rain could enhance heat loss under light winds, while lingering moisture or southerly shifts might keep minima higher. Ensemble forecasts diverge on exact boundary-layer conditions over the Bosphorus region, creating balanced market-implied odds near the 7°C and 17°C thresholds. Updated high-resolution runs from agencies like ECMWF will clarify steering patterns and dew point depressions ahead of 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.
