Recent forecast model runs from agencies tracking central Turkey indicate a persistent rain system arriving over Ankara on October 17, with totals exceeding 20 mm and associated cloud cover limiting solar heating. This setup favors daytime maxima clustered near 12–13°C, aligning with the market’s near-even implied probabilities for those outcomes versus 11°C or 14°C. Cooler-than-average advection from the northwest reinforces the suppression, while historical October baselines near 18°C highlight the anomaly. Updated ensemble guidance through the next 48 hours will refine exact peak timing and any brief clearing that could nudge readings higher.
