In the latest expectation of the visit of the Polar Vortex, the following maps depict it's growth and development along with subsequent plunge southward toward Southern Canada. It will influenced a large portion of Canada and northern US. First, however I'd like to note that "Polar Vortex's" are nothing new, they have been known of since their discovery in meteorology involving planetary winds and jet streams...and obviously, existed before their discovery.

Generally to a large extent. visit's from the vortex happens nearly every winter in the Great Lakes but during some winters, worse and more often than others. Most times we experience just an extension (or brush) of the cold core Polar vortex but occasionally, it's the whole enchilada. Take note of latest NCEP Ensemble model projections of our latest scheduled visit during the upcoming week (dates are at the top next to valid time and white x denotes Michigan on map).







We'll take a look at it's actual result by weeks end.

Making weather fun while we all learn,
