ECMWF deterministic shows a robust 26°C for Ankara on May 10, significantly driven by a dominant 500mb geopotential height ridge establishing across Anatolia. GFS aligns closely, projecting 25°C. Ensemble analysis is critical: ECMWF ENS has over 70% of members exceeding 24°C with tight spread, indicating high confidence in the warm anomaly. GEFS ensemble mean is also >24°C, with 65% probability. Strong warm air advection (WAA) at 925mb and optimal insolation under minimal cloud cover will enhance boundary layer heating. The synoptic setup firmly supports exceeding the threshold. This is a high-probability event based on core model consensus. 90% YES — invalid if a sudden shortwave trough disrupts the ridge axis on May 9.
