Great pics Michael. Amazing spell of weather for millions. -10c w/c of -20 today in Hamilton with light snow flurries. Down to -23c overnight and again tomorrow night, just stunning. For the first time in a long time Niagara Falls (American Falls) has completely frozen see below :

There's no maid of the mist on the Niagara river, some of the pics Reuters took from the American side make Canada or Ontario look like a frozen wasteland which is fairly accurate given the overhead temps!

Amazing incredible stuff, needless to say all of the GTA and Southern Ontario under an extreme cold alert. When it all melts, they'll be trouble

Take Care

Washington DC is forecast to breech 20C, Christmas Eve.

It will certainly melt given Tuesday to Friday will be above freezing and as high as 11c on Thursday. Will be next weekend before winter returns. Average high should be -6c in late December.

Interesting! Although when you realise that Baltimore is actually slightly further south than Corfu, you see why that would be possible. We're so used to thinking of America's cold, snowy Christmases, though far fewer in Maryland than in New England.
