Late Monday post: Winter is coming...again

Don't be fooled by the innocuous forecasts from Env. Can. and TWN.  Sunday may have quite a snow event.   The models have aligned in an unusual manner.   The GFS and Canadian have a system passing over the lower Great Lakes late Saturday into Sunday, giving the estimated snow amounts in the maps below.  The Euro and Japanese models however have the system shunted well to the south, not affecting Ontario with any significant snow amounts.  Stayed tuned for further updates.

Colder than normal temperatures will last at least two weeks:
Week 1:

Week 2:
