Indication of how cold it's been

Great lake ice is highest on record, going back 35 years anyway.

Rapid Great Lake freeze...

With the much below normal temperatures coming the next two weeks, we will see a rapid expansion of the ice cover, currently at 8.8%, especially over Lake Superior, Georgian Bay and Lake Erie.

Snow cover update

As noted last week, the western provinces have largely been covered with snow.

Canadian snow cover.

An update to my "prediction" wrt to Canadian snow by the end of October, here is the map of snow cover as of yesterday.  While there was some melting from a few days ago, the snow cover fell short of my prediction.   However, over the next week, the western half of the Country will get a lot whiter.
