This morning at my house: (kind of blurry)
-50.0 C, figured out that that's the lowest reading it could display. The time is wrong, it was that around 9:00 am.
It's now around -38 C.
A hour north of Winnipeg sure makes a big difference. But even in Winnipeg the temperature can fluxuate like ten degrees.
My 50 post at -50.0 C.
I also posted that in the Winnipeg Construction thread. Didn't notice that one until later.
