Overview
- New station highs include a roughly 12 °C December night in Bremen, with mountain sites such as Hohenpeißenberg also posting exceptional values, and the month currently ranking second-warmest since 1881.
- CFS and ECMWF runs now project positive anomalies of about 3 to 4 degrees through at least the third Advent, signaling low probabilities for a prolonged cold spell or widespread holiday snowfall.
- The DWD reports generally mild days but has issued level‑1 alerts for overnight frost and areas of dense fog in parts of Bavaria.
- While Europe stays unusually mild, northeastern parts of the United States and eastern Canada are experiencing severe cold and frequent snow under a contrasting jet‑stream setup.
- Some outlets note a brief late‑week cool‑down with localized frost, yet forecasters see no clear pattern shift before Christmas and stress uncertainty for the period after the holidays.
