September summer fades this weekend; massive climate strike turnout

Spotty thunderstorms Saturday

Six in a row.

Friday was the 6th straight day with temperatures in the 80s across much of Minnesota. I saw 90 degrees Friday afternoon in Canby and Madison in western Minnesota. Take a good look at the temperature map below. You may not see this much red on the map this far north for another 7 or 8 months.

So far September is running nearly 4 degrees warmer than average in the Twin Cities and most of Minnesota. After another year with heavy April snows, we earned an extra month of summer this year.

Scattered storms Saturday

Low pressure spins from North Dakota into southern Canada this weekend. The system drags a cold front across Minnesota. The best chance for storms favors northern Minnesota through Saturday. Many short-range models suggest smaller clusters of storms near the Twin Cities Saturday morning, but the best forcing remains in northern Minnesota.

Here comes fall

Astronomical fall begins at 2:50 am Monday. The weather maps seem to get the picture. Temperatures run closer to average next week. The average highs in the Twin Cities by Monday is 69 degrees.

4-million turn our for Climate Strike

I’ve seen estimates as high as 4-million worldwide for Friday’s Climate Strike.

Regardless of which climate solutions people see as best, the groundswell of support for action on climate is remarkably noteworthy in the past year.

UN Climate Action Summit next week

The UN Climate Action Summit next week brings together a large coalition of leading climate solutions thinkers. The event focuses on the mechanics for action that can actually get the world to zero-carbon by 2050.
