Large Hail in the Twin Cities on Friday
Thanks to Mike Holisky for the picture below. Large hail fell across parts of the metro on Friday evening. Mike reported nearly golf ball size reports, but there were a couple reports of up to baseball size in the Twin Cities - YIKES!
Storm Reports From Friday
It was a busy day across the county warning area with a number of severe weather reports. Large hail was one of the main concerns with some 3" diameter hail reports coming in near Dassel. There was a baseball size (2.75") report from Buffalo Lake, and several 2" to 2.5" reports in Minneapolis.
Weather Outlook This Weekend
The weather outlook for the weekend ahead looks like a 50/50 split. Sunny and mild weather will take us through Saturday, but Sunday looks like a fairly soggy day with the potential of seeing some 1.00" plus rainfall tallies across parts of the state, especially north of the Twin Cities. Temperatures will also be quite a bit cooler with readings only warming into the 70s. Some folks across the northern part of the state will only make it into the 60s. Keep an eye out for any Perseid meteor showers early Saturday evening before the clouds rolls in.
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."

It Hasn't Been As Humid This Summer
By Paul Douglas
Hey, is that a silver lining or am I still hallucinating? No comment. It has been a summer of smoke and drought. No big soaking storms, just at ease of flash and dash showers. Since May 1 St. Cloud has picked up only 4.7" rain, the driest such period on record - even drier than the Dust Bowl of the 1930s.
There is one faint positive: nagging drought has meant fewer sweaty, swampy days where you walk outside and it feels like you're stuck in a sauna. The metro area has picked up only 6 days with a dew point of 70For higher. In an average year MSP sees 19 drippy days with a dew point of 70+. Hey, it's a start.
Welcome to the sunnier day of the weekend with 70s north and mid 80s in the metro. The next (unusually strong for August) Alberta Clipper pushes a smear of showers and T-storms across the state Sunday, with temperatures in the 70s statewide, and cool 60s up north. Winds may gust to 40 mph Monday before the pattern mellows by midweek.
No 90s in sight, but the Minnesota State Fair is creeping up. Oh yeah.

"GPS satellites threatened more by mild solar storms than monster sun flares"
"The most intense space weather event of the past two decades hit GPS satellites' orbit just after a solar minimum. Mild solar storms can cause more serious problems to GPS satellites than once-in-a-century events, a new study has found. Storms that erupt from the sun create challenges for satellites in Earth's orbit. Scientists are trying to understand these events better to help operators protect their spacecraft. And sometimes, they find surprises. A new study by researchers from the British Antarctic Survey (BAS) discovered that satellites in the Global Positioning System (GPS) orbit may suffer more from milder solar storms than from the frightening events that wreak havoc on power grids and telecommunication networks on Earth."
"Yellow jerseys of the fireline: A day fighting wildfires can require as much endurance as riding the Tour de France"
"For three weeks in July, the world's most elite bike racers climb steep mountains and sprint along historic cobblestones to capture the coveted yellow jersey or the race leader in the Tour de France. It's a 22-day feat of human endurance that requires constant eating and drinking to manage the average daily energy demand of about 6,000 calories, equivalent to around 12 McDonald's Happy Meals, and just over 1.5 gallons of water. Nearly 5,000 miles away in the mountains of North America, radios crackle with chatter from a wildfire incident command post, air operations and other crews fighting a wildfire. Up the fireline, the swings of Pulaskis, axlike hand tools, are carving a fuel break into the land. The weather forecast predicts a high of nearly 100 degrees Fahrenheit (38 C) with wind, a combination that can push the fire high up into the canopy of dense lodgepole pines on the mountainside. The yellow jerseys here are sooty, sweat-stained and flame-resistant, with a strong, earthy odor."

"The largest freshwater wind farm in the world"
"World's largest freshwater wind farm Windpark Fryslân began construction in 2020, and, by the fall of 2021, was already generating power. In 2022, the wind farm generated 1.236 terawatt hours. And its builders anticipate it will reach 1.5 terawatt hours every year. That's roughly 1.2 percent of the all the electricity used in the Netherlands. It's enough to power around 500,000 homes. Constructing the wind farm Constructing a wind farm in a lake (Lake IJssel in the central Netherlands) was challenging, to say the least. But the Netherlands has experience with building dikes and dams for flood control. One of the companies that helped build the wind farm, Van Oord, said: A major constraint was the size of ships that could be used to transport construction materials and turbine components to the site. The vessels had to both fit through the locks in the dike and operate in the shallow waters of the lake. In addition, installing the rotors, which are 130 meters (430 feet) in diameter, required finding windows of relative calm in a naturally windy place."
