April 22, 2026 Wednesday Spring Weather

Powerful winter storm system across Rockies moves into Canada with heavy snow

What the month did

April 2026 was the 3rd-warmest April in the 132-year national record (1895–2026), at 54.7°F against a 1991–2020 normal of 51.8°F (+2.9°F).

April 2026 was the 46th-wettest April in the 132-year national record (1895–2026), at 2.7in against a 1991–2020 normal of 2.7in (+0.0in).

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.

Next 2-days: Impressive storm system that deepens into the 980s mb central pressure over Montana and the Canadian Prairies with significant snowfall — and cold air on the back side tapping into the “polar vortex” linked “cold pool” still operating over the Arctic.

Cold front attached to storm system will fizzle out while pushing off the East Coast, but hopefully we’ll get 0.25” of rainfall over the Southeast including the Carolinas.
