Weather warning as 'arctic express' jet stream is set to blast dozens of states with sub-zero temperatures The 'arctic express' is set to blast the Eastern US with another round of frigid air this week, sending temperatures plummeting 10 to 20 degrees F below average.
Hot, dry hurricane-force gusts should return to Southern California Monday afternoon and persist through Wednesday, reaching speeds of 60 to 100 mph and reigniting fire risk.
The jetstream will carry a blast of cold air through the Midwest, Northeast and Southeast starting January 15, with some states experiencing temperatures that feel as low as -30F.
While the East braces for freezing temperatures, the West Coast is poised for a resurgence of the Santa Ana winds that have triggered deadly wildfires in Southern California.
The National Weather Service (NWS) issued new fire weather warnings Sunday, warning of a 'particularly dangerous situation' for Los Angeles through midweek.
