Recent forecast model consensus, including GFS runs and agency guidance, points to overnight cooling under partly cloudy skies and northeasterly flow, with the daily minimum expected to reach 16°C in Istanbul on September 15. This aligns closely with climatological norms for mid-September while reflecting slightly cooler conditions than recent days. Trader positioning heavily favors 16°C at over 54% implied probability, as current observations and short-range guidance show temperatures bottoming near that threshold before daytime warming. Limited model spread and stable steering patterns reduce the likelihood of notable deviations, though minor revisions in evening data could still influence final recorded values.
