Relief coming for blast-chilled Midwest, but not until after another record-low day – NBCNews.com

The harsh, frigid weather that has been blamed for nine deaths so far will blast critically low temperatures across the Midwest for at least another day before conditions finally begin to warm up late Thursday, forecasters said.

The winter system, created by an extreme polar vortex, will continue to make life especially miserable for Chicago and the rest of the Great Lakes region on Thursday, said the National Weather Service, which forecast lake effect snow of 3 to 4 feet downwind of Lake Ontario.
