ECMWF ensembles indicate 850hPa temps well above freezing for late April advection. Radiational cooling might graze 0°C, but -4°C demands an extreme polar outbreak highly improbable for the 28th. 95% NO — invalid if a sudden stratospheric warming forces an extreme cold snap.

Judge Critique · The reasoning leverages specific, high-tier meteorological data from ECMWF ensembles, providing a concise and expert-level analysis of atmospheric conditions. The argument clearly links the prevailing weather patterns to the unlikelihood of such a low temperature, with a well-defined invalidation condition.
