U.S. and Canada border.

I see where our local weather stations in Michigan do include (on a small level), weather conditions in Ontario, Canada.  Beyond Ontario, I have grave doubts.  According to the map of Maine, blizzards stop at its northern border.  The weather becomes all clear.  This however, is not the case, having heard from my New Brunswick (Canada) cousins.  That darned blizzard snuck right across the border and they got 30 cms. (you'll have to look it up).  Hard to believe we in the States didn't even notice..........................marge
