– Snow could hit as many as seven states by Tuesday (Ice Age Now, Sep 6, 2014):
Winter weather isn’t waiting for the calendar.
Snow could hit Montana, Wyoming, the Dakotas, Minnesota, Wisconsin, and Michigan during the next week, along with a significant ‘chill in the air’ over the Great Lakes region.
For the lucky in Wyoming, that snow will only fall on the mountains.
“The predicted snow is about a month early,” says climatologist and former NASA scientist Dr Roy Spencer.
Forecasters believe the early temperature drop is due to a polar vortex.
