Polar Vortex Arctic Blast to HIT America Next Week

Arctic cold will return to the nation's northern tier starting late this week, and that could help fuel another widespread snow threat from the Rockies into parts of the Midwest and East.

 Strong arctic high pressure will bring much colder air southward from Canada into the Plains, Midwest and Great Lakes late this week into next weekend. A storm system entering the West Coast Thursday will tap into that cold air once it moves through the central and eastern states Friday through next weekend, potentially allowing the storm to deliver a widespread area of snow.

 This icy cold blast is brought on by a polar vortex. This polar vortex took a twist, literally. It split into 3 whirling cones of cold. Weathermen found it hard to say exactly what would happen but then did predict a high chance of extreme cold polar blasts to hit in up to 3 different directions.

 Producing extreme cold temperatures, high winds, heavy snow and ice. The polar vortex's are typically strong and it could send weather to blanket much of the United States with a polar blast next week.
