Montreal weather: Colder, flurries and a deep freeze overnight - Montreal Gazette

In February 1983, a blizzard buried Washington, Baltimore, and Philadelphia in up to two feet of snow. In January 2016, another historic blizzard shut down the same cities. Both events struck during Super El Niño winters, which most people expect to be mild. Now an even stronger Super El Niño is building toward its December peak ahead of Winter 2026/2027. The latest October forecast data points to a milder northern U. S. and southern Canada, an active and stormy South, and a mild Europe. It also shows a notable shift toward a colder, snowier south-central and eastern U. S., and an unusual Polar Vortex disruption signal around mid-winter. I will break down what shifted in the latest winter forecast data, how the season is expected to unfold, and which other major winter storms past Super El Niño winters delivered.
