**Forecast models from sources including GFS, ECMWF, and local meteorological services indicate a stable high-pressure pattern over the Marmara region through September 19, with northeasterly winds and mostly clear skies favoring moderate overnight radiative cooling.** Expected minimum temperatures cluster around 18–19°C, consistent with late-summer climatology for Istanbul. The near-even market split between 13°C-or-below and 23°C-or-higher outcomes reflects residual model spread in boundary-layer cooling rates and any last-minute shifts in cloud cover or wind strength, rather than competing signals from major synoptic features. No significant cold-air advection or heatwave setup is present in current runs, keeping the distribution tightly centered near the middle of the posted range. Updated model guidance ahead of the 48-hour window will be the key catalyst for any adjustment in trader positioning.

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.
