USA Weather This Week (January 5–12, 2026): City-by-City Forecast
As of January 5, 2026, the United States is seeing a classic early-January weather divide. The West Coast, particularly California, continues to deal with active storm systems bringing heavy rain and mountain snow, increasing flood risks in Northern and Central areas. Meanwhile, much of the East and Midwest are transitioning from recent cold snaps to a gradual warmup, with temperatures climbing toward or above normal by mid-to-late week. A weak La Niña influence persists, favoring wetter conditions in the Northwest and variable patterns elsewhere.
This week offers relief for many after the holiday chill, but travelers in the West should monitor flood and mudslide alerts. Here’s a detailed city-wise forecast based on the latest data from NOAA, NWS, and major weather services.

A chance of light rain or drizzle appears around January 10–11 as temperatures peak near 57°F (14°C), followed by a cooler, clearer end to the week (highs dropping to the upper 30s°F).
