Nature's April Fools.

It's fair to say pretty much everyone in Saskatoon considers April 1 to be spring.  But you wouldn't know it by the weather today.  When I got up this morning it was around -20 C.  It snowed yesterday, and a bit more today.  So it looks like November here.  It's not supposed to get above freezing until Monday.  This is one April Fools trick I don't appreciate.
