October 28, 2024 Monday Weather Update

Very warm Halloween for eastern Lower 48

What the month did

October 2024 was the 2nd-warmest October in the 131-year national record (1895–2025), at 58.9°F against a 1991–2020 normal of 54.5°F (+4.4°F).

October 2024 was the 3rd-driest October in the 131-year national record (1895–2025), at 1.0in against a 1991–2020 normal of 2.5in (-1.5in).

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.

Sorry for the late update — a few things came up including an interview with the AP on persistent dryness over the past month since Hurricane Helene. The 30-day precipitation anomaly (% of normal) shows the Lower 48 at 31% of normal when spatially averaged. Of course Milton comprises the largest positive anomaly over Florida. Thankfully relief is on the way for the Central U.S. with boatloads of rainfall as the Gulf of Mexico finally opens for business.

I’d also like to draw your attention to Cliff Mass blog on “The Unnecessary Decline of U.S. Numerical Weather Prediction.”
