US EditionA Triple-Dip Polar Vortex Is Coming. Will Your State Feel the Chill?
Three waves of Arctic air will cause frigid temperatures, snow, and ice across central and eastern U.S., increasing energy demand and challenging record lows, experts said.
- On Dec. 4, AccuWeather and the National Weather Service warned three polar vortex systems will push Arctic air into the central and eastern United States, causing frigid temperatures.
- Meteorologists note the polar vortex is a large Arctic circulation that normally contains cold air near the North Pole, but shifts in the jet stream can push Arctic air south.
- Models project gusts and low wind-chill readings with Dec. 4 wind chills plunging between minus 10 and minus 25 degrees, Thursday night lows near 15 degrees and gusts up to 34 mph.
- AccuWeather cautioned that the cold will cause surges in energy demands, hazardous travel on untreated roads, bridges and overpasses, and local agencies posted Lower Hudson Valley warming shelters and HEAP contacts.
- Mid-December forecasts suggest frigid temperatures will hit the Midwest and Northeast, with the jet stream reaching the Tennessee-Kentucky border, so officials urged residents and utilities to winterize homes and check heating systems soon.
