Ridge Development Shifts Temperatures Nationwide The National Weather Service reported that a strengthening high‑pressure ridge began building over the United States on Saturday, February 4, 2026, replacing the Arctic air that dominated January. The ridge is expected to push milder air across most of the country through mid‑February. Forecast models show highs 10‑20 °F above normal for central and eastern regions, providing a noticeable break from the previous weeks of freezing temperatures [1].

Northeast and Midwest Retain Arctic Cold deepening trough in the eastern U.S. continues to channel Arctic air into the Northeast and parts of the Midwest, keeping temperatures in the single digits with wind chills well below zero. The trough moves slowly eastward, so the cold pocket will persist into the second week of February. Residents of New England and the Mid‑Atlantic can expect continued icy conditions despite the warming elsewhere [1].

Warm Spell Relieves Storm‑Impacted Communities Communities still recovering from recent snow and ice storms benefit from the temporary milder weather, as reduced heating demand eases strain on power grids. Road crews report faster clearing of icy surfaces, and travel disruptions lessen across the Midwest and South. Officials note that while winter is not over, the pause allows infrastructure repairs to progress [1].

Forecast Highlights Seasonal Anomaly Meteorologists emphasize that the contrast between the warming ridge and the lingering cold trough creates a rare early‑February temperature gradient. The pattern could set records for above‑average highs in several states, while the Northeast may record one of the coldest February weeks on record. The situation underscores the volatility of the 2026 winter season [1].
