YES. GFS and ECMWF ensemble means consistently flag 850hPa thermal profiles exceeding +11°C for Ankara on April 27. A dominant high-pressure ridge will drive warm advection and robust boundary layer mixing under clear sky conditions. This synoptic pattern ensures strong insolation and efficient surface heating, pushing max temps well into the 23-25°C range. The 21°C threshold is a soft breach target. 90% YES — invalid if low-level cloud persistence exceeds 40% cover.
