Meteorological modeling from MetService and ECMWF consistently projects a cold front impacting Wellington on April 29. Current ensemble means peg the maximum temperature around 10-11°C, with a median of 10.5°C across the major models, significantly undershooting the 12°C threshold. Baroclinic zone dynamics support this cooler airmass intrusion. 95% NO — invalid if frontal system trajectory shifts significantly westward.
