Tornadoes That Should Have Been Rated EF5: El Reno, Greenfield, Rolling Fork and the Rating Debate

The tornadoes most often argued as EF5: El Reno (EF3 despite 295+ mph radar winds), Greenfield (EF4, radar-derived 309–318 mph), 15 high-end EF4 candidates and 2026's Enid EF4 — and why the scale rates damage, not wind.

El Niño and the 2026-27 Ski Season: Which Mountains Tend to Win, and Which Lose

We checked April 1 snowpack near 17 ski regions in every strong El Niño winter since 1972. The Northwest came up short, Arizona and New Mexico usually boomed, Utah and Colorado showed no signal, and even the winners had a melt-out year.
