April 4, 2024 Nor'easter Won't Quit

Quiet weather across Central U.S. + Eclipse forecast looking up

What the month did

April 2024 was the 15th-warmest April in the 132-year national record (1895–2026), at 53.6°F against a 1991–2020 normal of 51.8°F (+1.8°F).

April 2024 was the 37th-wettest April in the 132-year national record (1895–2026), at 2.8in against a 1991–2020 normal of 2.7in (+0.1in).

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.

Quick look at the 15-day upper-level pattern from the ECMWF AIFS 12z showing the eventual development of an Eastern Ridge next weekend and then a Western Ridge by the end of the 2-weeks. In between, lobes of the polar vortex cut-off like bowling balls through the southern U.S. — any which of these could be the focus mechanism for severe weather.

The next 48-hours from HRRR showing the Nor’easter still spinning on Saturday! It loops back for a final brush by of Boston — to say goodbye on Sunday. Ugly!
