Frost possible in the Twin Cities, Green Bay, Milwaukee, even Chicago by next weekend, coming nearly 2-3 weeks earlier than usual. Details below.
"Starting on Tuesday, consumers east of the Rockies will be reaching for a fleece jacket during the day and an extra blanket overnight. While some areas enjoyed cooler overnight conditions this week, next Tuesday and Wednesday (September 18th & 19th) is expected to bring a 25 to 30°F decrease for both day time and overnight temperatures compared to recent weeks across the Northern Plains and Western Great Lakes. Frost is likely across these regions, including the major population areas of Minneapolis, Green Bay, Madison, and Milwaukee."

Crops and cattle in drought have begun to rise again. Overall, drought has shifted toward the north and west in recent weeks.

Details from Digital Typhoon: "Typhoon SANBA was formed in Caroline Islands. Palau is now within the gale-force wind area. The typhoon is forecast to move northward off the east coast of Phillipines, which is known to be a favorable area for typhoon intensification, so we need to keep alert on the development of the typhoon."

An Early October?
September flurries in the Twin Cities are unusual, but not unprecedented. On September 24, 1985 nearly a half inch of slush delighted MSP residents. No, really! Why am I bringing this up? I sense that it's almost payback time for a record warm summer. 95F on Tuesday was only the 8th time it's been that hot on or after September 11 since 1891
What goes up must come down. Record heat is often followed by unusual chill, as the atmosphere attempts to reach equilibrium. I've seen it happen too many times.
We're in uncharted waters (literally) over the Arctic; now one Big Slushie. How record heating at the top of the world trickles down into our latitude has yet to be determined, but I'm betting the farm that autumn will not come quietly this year.
An October-like SLAP is shaping up for next week. Expect a few raw-gray days: 40s north and 50s south; an early frost here - even a coating of slush for Duluth by next Sunday? No, I'm not kidding. We'll see more 70s come October, but for now: early jackets.
Enjoy 80s this weekend. Not sure when we'll see this again.
Then again, you can't call it Indian Summer until you've endured the first frost, which should come early this year.
