Current atmospheric conditions and ensemble forecast models indicate a peak temperature of 22°C as the most probable outcome for Istanbul on May 17, underpinning the dominant 96.2% market-implied probability. Regional May climatology under stable high-pressure patterns typically produces daily highs of 20–24°C, with short-range numerical weather predictions showing consistent afternoon maxima and low spread across guidance. Official monitoring confirms steady temperature profiles without significant frontal passages or warm-air advection expected today. A sudden shift in steering winds or localized measurement variance at the primary station could still push the reading outside this narrow band, though model consensus and recent observational trends make such deviations improbable before daily resolution.

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.
