Are you ready for the return of the polar vortex?  I know I am not!  According to MLive Meteorologist Mark Torregrossa, it's going to be quite a bit cooler than normal at the beginning of next week.  A piece of the Polar Vortex which is usually non existent at this time of year will cool things off significantlyHow cold will it get?  How about highs in the upper 60's?  That's about 15 to 20 degrees cooler than normal and overnight lows could be 45-50 degrees.  I guess it's time to get the comfy sweats and sweatshirts out for a more comfortable July :/
