Last week at this time it was below -30C with windchills, and had been for about a week straight. Now I see a +8C in the forecast! What a slingshot.
What's really wild though is that that kind of wild temperature swing is normal here! (Likely exaggerated by climate change, but well within historical temperature swings.) This is one reason it's hard for random farmers here to believe in climate change - the climate here is already wacky.
