Fall Color Update

It's that time of the year again for fall colors and the MN DNR has their fall color finder up and running. Much of the state is still color free, but there are a few colors popping up here and there.

Average Fall Color

The MN DNR has put together a nice graphic that shows typical dates for peak fall color. The northern par of the state starts to peak during the 2nd half of September into early October. Meanwhile, folks in the central part of the state and into the metro typically don't see peak color until the end of September into the middle part of October. It won't be long now - enjoy!

A Taste of Early August in Mid-September
By Paul Douglas

Cue Deep Purple's "Smoke On The Water". The short-term outlook calls for haze and smoke from western fires being swept high overhead. Otherwise Mother Nature is napping. She's on her best behavior after 76 (preliminary) tornadoes in Minnesota in 2022, more than most states in Tornado Alley. Then again tornadoes don't usually spin up during heatwaves or drought.

Our boringly-beautiful weather streak continues with August-like temperatures into early next week. I see 80s into at least Tuesday - 90F is possible on Monday. "That's all well and good Paul, but you DO know we're in a nagging drought. How does that make you FEEL?" Sad, but I'm just a bewildered observer.

I do see wetter days ahead with a good chance of a few swarms of T-storms Friday, Saturday night, and potentially heavier rain by the middle of next week as cooler air returns. In the meantime, forget the calendar. It's early-August out there.

I've unplugged the Doppler. Time to walk the dog in my short-shorts and antagonize the neighbors.

Climate Stories

(NOAA/The Minnesota Star Tribune)

"Climate tipping points study provides clearest warning yet"

"A new assessment of tipping points within the climate system concludes that far more stringent emissions cuts are needed, compared to the most ambitious current plans. Why it matters: The new study, published Friday in Science, finds tipping points lurking much closer to the present level of warming, and that the Paris Agreement's most stringent warming target of 1.5°C compared to preindustrial levels could trigger four of them. These would include the abrupt thawing of permanently frozen soil that rings the Arctic and the die-off of warm-water coral reefs. Context: The study defines a tipping point as when changes in a large part of the climate become self-perpetuating. Not every tipping point immediately affects the planet, and some are only felt regionally. Still others — like the melting of the West Antarctic Ice Sheet, could take centuries to fully play out."

"Giant hailstones are breaking new records"

"On Aug. 1, a team of scientists from Western University in London, Ontario, collected a giant hailstone while chasing a storm in Alberta, about 75 miles north of Calgary. The hailstone measured five inches across and weighed a little more than half a pound … The Canadian hailstone added to the list of regional records set in the past couple of years, including Alabama's in 2018 (5.38 inches long, 0.612 pounds), Colorado's in 2019 (4.83 inches, 0.53 pounds) and Africa's in 2020 (around seven inches long, weight unknown). Australia set a national record in 2020, then set it again in 2021. Texas' record was set in 2021. In 2018, a storm in Argentina produced stones so big that a new class of hail was introduced: gargantuan. Larger than a honeydew melon."

"Megadrought in the American south-west: a climate disaster unseen in 1,200 years"

"When the Nasa climatologist James Hansen testified before Congress in June 1988 about a warming planet, the temperature in Washington DC hit a record 100F. It was a summer of unprecedented heatwaves, and 40 states were grappling with drought. His warning was seen as a historic wake-up call – but instead of heeding the existential smoke alarm, the US removed the batteries and kept on cooking. Nearly four decades later, the consequences of a sweltering Earth are hitting home in the US south-west and mountain west – comprising states from California to Colorado. Over the past two decades, extreme heat and dwindling moisture levels have converged to create a "megadrought" deemed the driest period in 1,200 years."
