Midweek Warm-Up to Flip Back to Arctic Chill as Rain Turns to Snow Across Midwest and Northeast

Forecasts point to volatile swings driven by fast clippers, with a new Arctic outbreak late in the week.

The gloomy weather continues with fog and low clouds in the Valley, Delta, the Bay Area, and even portions of the Foothills.

Overview

  • A widespread cold pattern continues with many regions logging the coldest mornings of the season and highs well below normal.
  • A brief Tuesday–Wednesday rebound will lift temperatures above average in spots, setting up rain that changes to snow across the Midwest and Great Lakes, including Chicago, with gusty winds and localized travel impacts through late week.
  • In the Northeast, single-digit and teen lows give way to rain for most on Wednesday with a mix or snow in higher terrain, followed by a turn back to colder air and fresh snow chances into the weekend.
  • The National Weather Service is signaling another Arctic surge next weekend across the northeastern U.S., with overnight wind chills potentially below zero.
  • Regional hazards persist in California with persistent Tule fog and overcast in the Central Valley, while warm, dry Santa Ana winds early this week bring elevated fire risk in Southern California.
