    -20F is -28C. I remember it hit -28C one time when I was a kid. I was walking around a forest and no trees exploded.

      It’s not a common thing. And they don’t “explode” as much as shatter. It does require enough sap to be up in the tree trunks too. And our trees are too smart to let that happen for the most part. But it can and does happen sometimes to thin spindly young trees.

      It’s been pretty cold up here in far northern Minnesota since last Wednesday. With morning temps at -25F, -30F, -30F and -35F this morning. The high yesterday was -15F and a high of -5F today. It’s not the very low temps that bother anyone up here, it’s the windchill that will kill you. Yesterday, the wind chills were running -35F to -60F. Which can cause frostbite to exposed skin in 5 minutes or less and possibly kill you very quickly.

      On the upside, at these temps large amounts of snowfall are almost impossible. So I won’t need to start a tractor and plow the mile and a half to the nearest plowed road.
