Major winter storm will drop 1-2 feet of snow, and heavy icing and sleet

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).

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.

Very quick post on the HRRR 00z showing the winter storm into Sunday. Holy moly!
