December 31, 2024 Final Update of Year

Winter storm still on schedule next week for Ohio River Valley, maybe into D.C.

What the month did

January 2025 was the 33rd-coolest January in the 132-year national record (1895–2026), at 29.2°F against a 1991–2020 normal of 32.3°F (-3.2°F).

January 2025 was the 5th-driest January in the 132-year national record (1895–2026), at 1.4in against a 1991–2020 normal of 2.3in (-1.0in).

NOAA/NCEI Climate at a Glance, contiguous United States. This is the observed record for the month, not a score of anything said in this piece — the forecast ledger begins 2026-08-17 and cannot reach earlier posts.

January 2025 looks to be cold East of the Rockies, but will we see Nor’easters? So far, the extreme cold guarantees mountains of Lake Effect snowfall in the Great Lakes, but other than a few Clipper systems, that admittedly have outperformed, many metro regions are overdue for an old-fashioned winter storm or blockbuster blizzard.

Holy moly — did GFS 18z drop the “polar vortex” hammer. A global model forecast for the ages.
