Latest ECMWF and GFS ensemble forecasts project Istanbul's highest temperature on April 3 clustering around 15-17°C under partly cloudy skies with possible rain showers, aligning with trader consensus assigning 46% implied probability to 17°C or higher, 27.5% to 16°C, and 19.5% to 15°C. Recent heavy rainfall and yellow-code alerts from the Turkish State Meteorological Service (MGM) have suppressed temperatures, with today's high near 16°C amid intermittent showers following yesterday's 19°C peak. Mild southerly winds and lingering moisture introduce uncertainty, as cloud cover could cap highs below 17°C, while partial clearing might push toward the upper end. New model runs expected overnight and tomorrow's observations will refine probabilities before resolution based on official Istanbul Airport measurements.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column on the specified date once information is finalized for all hours on that date, available here: https://www.weather.gov/wrh/timeseries?site=LTFM
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve to "Yes" until data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
