Absolute NO. The climatological data for Ankara in May unequivocally signals against a -9°C high. Mean monthly climatology for May shows average high temperatures typically range from +20°C to +25°C. A -9°C high represents a catastrophic negative thermal advection anomaly of over 30°C from the ensemble mean, firmly aligning with mid-winter isotherm patterns, not late spring. For such an extreme scenario, you'd need an unprecedented, sustained Arctic polar vortex displacement directly over Anatolia, combined with extensive, persistent snow cover to drive down surface albedo and amplify longwave radiative cooling. Historical extreme minimum daily *highs* for Ankara in May rarely dip below +5°C, making -9°C for a high astronomically improbable. This isn't just low probability; it's outside the bounds of rational meteorological expectation for the region at that time. 99.99% NO — invalid if a cataclysmic, sustained stratospheric warming event above the polar cap induces an unforecasted, multi-week arctic outbreak directly into Anatolia during early May, an event not seen in instrumental records.
