Synoptic analysis and climatological normals for Ankara in May show daily high temperatures averaging around 18°C. Historical records indicate extreme May lows rarely dip below 0°C, making a -6°C daily high an astronomical statistical outlier. Current GFS and ECMWF medium-range models show no anomalous cold advection or polar vortex intrusion. This event is multiple standard deviations from the mean. My ensemble forecasts assign negligible likelihood. 99% NO — invalid if a sudden, unprecedented arctic front impacts Anatolia.
