Slow Moving Storm Brings Much Needed Rainfall

A slow moving storm will increase our rain and rumble risk through the rest of the week with the wettest days late Thursday through Saturday. If weather models are accurate, backyard rain gauges could approach 1 inch for many across the state by this weekend. Check the blog for more details. -Todd Nelson

Slow Moving Storm Brings Much Needed Rainfall
By Todd Nelson, filling in for Douglas

Hard to believe, but the Great Minnesota Sweat Together is only a week away. For Minnesotans, this marks the unofficial end of summer, where you can get anything on a stick right up to Labor Day. If food on a stick doesn't fit your fancy, try the new Reuben rolls or pickle pizza!

While your mouth waters, chew on this; we've lost nearly 1 hour and 40 minutes of daylight since the summer solstice and will lose another hour through Labor Day. It's inevitable, winter is coming, just like Game of Thrones told us, but we'll still have plenty of wonderfully warm and sunny days yet this summer and fall.

Unfortunately it won't be any of the days in the near future. A slow moving storm will increase our rain and rumble risk through the rest of the week with the wettest days late Thursday through Saturday. If weather models are accurate, backyard rain gauges could approach 1 inch for many across the state by this weekend.

Beachgoers will likely need a plan B, but lawns and gardens will very happy! So happy, they'll wet their plants!

"The science of why you have great ideas in the shower"

"If you've ever emerged from the shower or returned from walking your dog with a clever idea or a solution to a problem you'd been struggling with, it may not be a fluke. Rather than constantly grinding away at a problem or desperately seeking a flash of inspiration, research from the last 15 years suggests that people may be more likely to have creative breakthroughs or epiphanies when they're doing a habitual task that doesn't require much thought—an activity in which you're basically on autopilot. This lets your mind wander or engage in spontaneous cognition or "stream of consciousness" thinking, which experts believe helps retrieve unusual memories and generate new ideas. "People always get surprised when they realise they get interesting, novel ideas at unexpected times because our cultural narrative tells us we should do it through hard work," says Kalina Christoff, a cognitive neuroscientist at the University of British Columbia in Vancouver. "It's a pretty universal human experience."

"An "Extreme Heat Belt" will soon emerge in the U.S., study warns"

"A new study reveals the emergence of an "extreme heat belt" from Texas to Illinois, where the heat index could reach 125°F at least one day a year by 2053. The big picture: In just 30 years, climate change will cause the Lower 48 states to be a far hotter and more precarious place to be during the summer. The findings come from a hyperlocal analysis of current and future extreme heat events published Monday by the nonprofit First Street Foundation. The new report is unique for examining current and future heat risks down to the property level across the country, and joins similar risk analyses First Street has completed for flooding and wildfires. As average temperatures increase due to human-driven greenhouse gas emissions, mainly from the burning of fossil fuels for energy, instances of extreme heat are forecast to escalate. This report makes clear where households will be vulnerable to what would now be considered almost unheard-of heat indices, which show how the air feels from the combination of air temperature and relative humidity."

"West's Drought Recovery Still Years Away Despite Recent Monsoons"

"Heavy monsoon rains have helped to relieve the Southwest's historic drought, but water officials say the deluge isn't enough to reverse a drying trend that has depleted the region's primary water sources. Much of the West remains entrenched in a 23-year "historically unprecedented" drought driven by climate change, said Jonathan Deason, an environmental engineering professor at George Washington University. "It's going to take about three years of above-average rainfall to have substantial recovery," he said. Most of the Southwest has received more than double its normal amount of rain since June, according to the latest US Drought Monitor. Some areas, especially in New Mexico, have seen drought conditions improve over the summer from exceptionally extreme to just severe or abnormally dry."
