Weather report

The National Weather Service is predicting thunderstorms with damaging winds, large hail and lightning strikes for this afternoon. This has become a pretty typical forecast for Minnesota. This is not the weather I remember. But it's what we have now. As the atmosphere warms, it can hold more moisture; and a hot atmosphere is a more energetic atmosphere.

There was a tornado warning for Ely, Minnesota a couple of days ago. Ely is so far north that it is almost in Canada. We didn't used to get tornadoes that far north. Maybe in the Red River Valley in northwest Minnesota, which is up against the North Dakota plain. But not in the northeast forest, which is where Ely is.

My sense is, the weather is more erratic. It goes from hot to cool and back rapidly, from day to day, with more storms.
