Springlike warmth threatens record highs as above-average temperatures spread across US again this week

Arctic air will remain absent from the U.S. for the next two weeks as a ridge of high pressure parks itself over southern Canada and the jet stream floods the nation with mild air from the Pacific Ocean. Springlike warmth is expected across the South with highs in the 60s and 70s, while the northern states will see multiple days of record warmth starting Tuesday as temperatures climb into the 40s and 50s.
