Thanks to a strong upper low spinning over eastern Canada, parts of the Great Lakes are seeing their first big Lake effect snows of the season and a pipeline for cold Arctic air has been established from northern Canada directly into the southeast U.S.   Due to this pipeline many cities in the southeast U.S.  saw record or near record lows this morning. 

Afternoon highs in many parts of the southeast U.S. are running about 20 degrees below normal.  In fact lows this morning were colder in much of the southeast U.S. than typical cold locations such as big cities in the northeast U.S. and even the intermountain west, which is seeing an usually mild pattern today.  For instance as you can see in the plot above Wilmington's morning low was colder than Boston's.  Clearview, FL had a colder morning low than Yellowstone Park in Wyoming.  Florence, SC saw a morning low thirteen degrees below New York City.  A weather world turned upside down, at least for this morning. Thanks to the National Weather Service office in Wilmington for providing some of temperatures used in this story.
