Weather Perfection Spills Into Labor Day

After a weekend tantrum of wind, hail and high water, Mother Nature will be on her best behavior. Winds ease today with mid-80s. Expect upper 80s Friday before a blip of cooler, Canadian air treats us to 70sSaturday and Sunday; maybe 80F on Labor Day. A lonely T-shower may pop Friday night; again Monday but a serene, San Diego-like sky hangs on. Check the blog for more details. -Todd Nelson

Weather Perfection Spills Into Labor Day
By Paul Douglas

Stuff I didn't expect in 2022: it's been one of the windiest years on record statewide, according to the MN DNR. Solar panels are great, but will someone PLEASE invent small, shrub-size wind turbines to power our homes?

With the5 confirmed (EF0) tornadoes that hit Dakota and Ramsey county Saturday night we may be up to 75 tornadoes in Minnesota so far this year. That's more than Kansas, Nebraska and Oklahoma! In fact only Alabama, Mississippi and Texas have observed more twisters in 2022. Mercifully, most have been small and brief. Very weird.

Another head-scratcher: unusually nice weather on a Labor Day weekend. After a weekend tantrum of wind, hail and high water, Mother Nature will be on her best behavior. Winds ease today with mid-80s. Expect upper 80s Friday before a blip of cooler, Canadian air treats us to 70sSaturday and Sunday; maybe 80F on Labor Day. A lonely T-shower may pop Friday night; again Monday but a serene, San Diego-like sky hangs on. This is why September is my favorite month.

Climate Stories

(NOAA/The Minnesota Star Tribune)

"Get ready for Southern California's hottest and longest heat wave of the year"

"A new week, a new month, a new heat wave — this one the hottest so far this year. The National Weather Service has issued an excessive heat watch for much of Southern California, as temperatures are expected to hit triple digits this week and into Labor Day weekend. This week's excessive heat for the region will be the warmest and longest heat wave so far this summer, said David Sweet, a meteorologist for the National Weather Service in Oxnard, adding that record temperatures are possible. A large dome of hot air sitting over Central and Southern California is driving the heat wave, Sweet said."

"Haboobs Are Mother Nature's Worst Dust Storms"

It was a sight to behold — one of the most incredible AccuWeather storm chaser Reed Timmer had ever witnessed up to that point in July 2018. A massive mile-high wall of dust was barreling toward afternoon commuters along Arizona interstates 17 and 8 near Phoenix. The ominous burnt-red curtain packed hurricane-force wind gusts, hail and torrential rains, choking rush hour traffic in near-zero visibility as it made its way westward. Dust storms are not unusual in the arid desert of southwest Arizona. But this one? Veteran Arizona storm chaser Mike Olbinski tweeted was "probably [one of the] top two haboobs I've ever chased."

"The untouched 'wilderness' of the Great Lakes is an illusion"

"An exotic species known as the zebra mussel, Dreissena polymorpha, a European mollusk, had found the Great Lakes a welcoming new home. Stowing away in the ballast water of a commercial vessel conducting cross-Atlantic trade, the mussels had disembarked in the lakes and, with no natural predators, had rapidly proliferated. And they had found surfaces to which they could cling. Although the interruption of Monroe's public drinking water supply was the first real alert to the general public that a new pest was in town, scientists had already been aware of the invaders. They had discovered the mussels in Lake St. Clair in 1988. But no one had predicted the explosion of zebra mussel populations in such a short time. Soon the species would become the headliner for a Great Lakes problem reaching back into the 1800s—the intentional and unintentional introduction of non-native aquatic organisms."
