Metro Area Hail Storms, August 9-10, 2020
Multiple, long-lasting, large hail-producing thunderstorms bombarded the Twin Cities Metropolitan Area and neighboring counties during the evening and overnight hours, with hail, gusty winds, intense rainfall, and non-stop lightning and thunder. The activity came in two waves. The first developed right around sunset on Sunday August 9, as compact but intense thunderstorms formed repeatedly across the southern Twin Cities, especially near Chaska, Chanhassen, Bloomington, and Burnsville. These storms lasted 2-3 hours and moved little, producing pockets of large hail and heavy rainfall. Reports of half-dollar to golf ball-sized hail were common, with hail the size of tennis balls photographed in Victoria. The second, larger, and longer-lasting wave of severe thunderstorms formed around 11 PM in Wright County, and spread southeastward very slowly over the next several hours. These intense supercell thunderstorms grew to the size of 2-3 counties, and produced multiple distinct cores of ping pong ball to tennis ball-sized hail, affecting areas from near Montrose and Buffalo in Wright County, to Loretto, Maple Plain, and Edina in Hennepin County.

Somewhat Hazy Wednesday
Thanks to a number of wildfires burning across Canada, skies closer to home will be a bit smoky and hazy on Wednesday. Air quality concerns continue through Midday Wednesday, where air quality have been posted across the northern half of the state. The air will be unhealthy for sensitive groups, like the very young or very old and those with lung or heart ailments.
Perseid meteor shower Peaks This Weekend
"When, where & how to see it - The Perseid meteor shower is one of the best shooting star displays of the year and it's currently active. The Perseid meteor shower (also known as the Perseids) is active every year from mid-July to late August. This year the shower will peak around Aug. 13, 2023, according to skywatching site In The Sky, 2023 will be a good year for the Perseids as the moon will only be 10% illuminated. The Perseids are caused by Earth passing through debris — bits of ice and rock — left behind by Comet Swift-Tuttle which last passed close to Earth in 1992. The Perseids peak when Earth passes through the densest and dustiest area on Aug. 11-12. Years without moonlight see higher rates of meteors per hour, and in outburst years (such as in 2016) the rate can be between 150-200 meteors an hour. On average, you can expect to see up to 100 meteors per hour during the Perseid's peak, according to NASA. In 2022, the Perseids were affected by the full moon illuminating the sky and washing out fainter meteors. However, this year the moon will provide minimal disturbance to the meteor shower as it will only be 10% illuminated during the time of the peak."

Every State Grapples With Weather Risk
By Paul Douglas
San Diego has the best climate in the nation, thanks to moderate breezes blowing off the Pacific Ocean. There is no perfect spot with perfect weather year round, but Hawaii comes close in spite of hurricanes and volcanoes. North Carolina is a pretty good choice for moderate climate.
I'm reading reports of people in Florida, Texas and Arizona becoming reluctant night owls: walking the dog, gardening, even shopping after the sun goes down. In recent days the heat index in Florida has been 115-120F. Florida is to summer what Minnesota is to winter. Deliriously character-building.
A weak cool frontal boundary may spark a few T-storms by late afternoon, with another round of gusty showers and T-storms Thursday night; again late Sunday. No big, sloppy southern storms brimming with moisture, just a sloppy parade of Alberta Clippers, each one preceded by a smear of showers - not the 3-day soaking we need right now.
I do see hints of September next week with 70s, maybe 60s up north. I'm very OK with that.

"Florida Could Soon Become Uninsurable—and Other States Will Likely Follow"
Florida is no stranger to extreme weather events, a fact that those living in Sunshine State have always factored in when insuring their homes. But as climate change exacerbates the frequency and severity of events like droughts, floods, tornadoes, and hurricanes in the U.S., the reality Floridians and insurers in the state are working with is quickly changing. Florida, according to several experts, is becoming "uninsurable." And other states, starting from California, might follow suit in the near future.
"80 Percent of People Around the World Experienced Climate Change-Induced Heat in July"
"July is supposed to be a hot summer month for the northern hemisphere, but last month was especially hot even for mid-summer. According to a new report released by science nonprofit Climate Central this week, climate change has made this July hotter for billions of people around the globe. Researchers looked at 4,711 cities around the world and found what the report calls "climate change fingerprints" in 4,019 of the locations last month. This study concluded that human activity and the fossil fuel industry made it three times more likely to be hotter this July."
"Huge 30-mile heat blob spotted on dark side of the moon has scientists concerned"
"An enormous heat blob is bulging on the dark side of the Moon and sparking scientists' fears. The worrying mass of heat - which is believed to have been caused by radiation - has been detected in an area of recently discovered granite deep beneath the moon's surface. Granite is created on earth as the leftover of a volcanic eruption as magma cools into the rock. And scientists say the moon deposit comes from a dead volcano that was once active around 3.5 billion years ago. Dr Matt Siegler, who works at Arizona's Planetary Science Institute, says: "This is more Earth-like than we had imagined can be produced on the Moon, which lacks the water and plate tectonics that help granites form on Earth."
