Obnoxious Heat May Return Next Week

A shower may pop Wednesday, again Saturday, but no widespread soakings are in sight. Enjoy this cooler front because some of that western heat returns next week with a streak of 90s. Check the blog for more details. -Todd Nelson

3rd Driest Summer Halfway Point For MSP

The stretch from June 1st to August 30th is known as meteorological summer, which is typically the warmest 3 months on average for the northern hemisphere. This is also the wettest season of the year, averaging nearly 13" of rain. We've now just passed the halfway point of meteorological summer and we've only picked up 1.69" of rain at the MSP Airport, which is tied for the 3rd driest start to any summer on record. The driest such period was back in 1988, when only 1.10" of rain fell.

60 Day Precipitation Anomaly

The map below shows the 60 day precipitation anomaly, which indicates that some locations are nearly -3.00" to nearly -7.00" below average (in red/pink) since mid May. Spots in Southwestern and northwestern Minnesota still have a bit of a surplus, but much of the region is well below average precipitation.

Drought Update

It has been an extremely dry stretch of weather across much of the station over the last several weeks. Only a few locations have seen decent pockets of rain, but the drought is expanding. Severe drought conditions have expanded from nearly 8.5% last week to nearly 11% this week, which encompasses parts of the east Metro. Moderate drought increased from 57% last week to 64% this week. We need rain!

Extended Precipitation Outlook

The extended precipitation outlook through the upcoming weekend shows a few pockets of heavier rain, mainly across the northern half of the state. Folks across the southern half of the state will stay mainly dry with only a few tenths of an inch of rain here and there.

Obnoxious Heat May Return Next Week
By Paul Douglas

Arctic cold wave or heat storm? The correct answer is neither, but you can always slap on more layers. Scorching heat? No thank you.

Friends in Scottsdale, Arizona describe a typical summer day: up early to walk the dog before sunrise. Careful not to touch door handles or other metal objects during the day. All shopping and entertainment takes place after dark, when temperatures "cool" into the 90s. They only come out at night. Desert Zombies.

I saw 116F in Las Vegas and 110F in parts of Italy and Spain. They're calling it a heat storm. This is peak summer but heatwaves are now supersized, thanks to El Nino and a warming climate.

According to the Twin Cities National Weather Service, much of eastern Minnesota is running a 6" rainfall deficit for the last 60 days, and historically the latter half of summer tends to be dry. A shower may pop Wednesday, again Saturday, but no widespread soakings are in sight.

Enjoy this cooler front because some of that western heat returns next week with a streak of 90s.

Climate Stories

(NOAA/The Minnesota Star Tribune)

"What's Happening in the Ocean, and Why It Matters to You and Me"

"Over the last five decades, we've burned enough coal, gas and oil, cut down enough trees, and produced enough other emissions to trap some six billion Hiroshima bombs' worth of heat inside the climate system. Shockingly, though, only 1 percent of that heat has ended up in the atmosphere. As extreme as the "global weirding" we're experiencing today is—people broiling under weeks of heat waves, wildfire smoke turning the skies orange, crops withering in prolonged drought, intense downpours inundating homes—most of it results from only a small fraction of all the heat that's been building up in the climate system. Instead, the majority of that estimated 380 zettajoules of heat, nearly 90 percent of it, is going into the ocean. There, it's setting ocean heat records year after year and driving increasingly severe marine heat waves. The ocean also absorbs about 30 percent of the carbon humans produce, adding up to almost 200 billion tons since the industrial revolution."

"'An Unstoppable Force': Wind and Solar to Produce More Than a Third of Global Power by 2030, Report Says"

"Solar and wind projects are on course to make up more than a third of global energy capacity by 2030, according to a report by U.S.-based clean energy nonprofit the Rocky Mountain Institute (RMI). The report said the growth demonstrates that the energy sector will be able to take the necessary steps to meet worldwide climate targets, reported Reuters. Solar and wind currently generate around 12 percent of electricity worldwide, but that is expected to grow to a minimum of 33 percent, offering less expensive energy and pushing out fossil fuel-generated power, the report said. "Exponential growth of clean energy is an unstoppable force that will put more spending power in the pockets of consumers," said Kingsmill Bond, senior principal at RMI, in a Climate Action press release. The research by RMI was conducted in cooperation with the $10 billion Bezos Earth Fund, started by Amazon founder Jeff Bezos. According to research from Systems Change Lab, eight countries have built solar and wind generation capacity faster than what is necessary to limit global heating to 1.5 degrees Celsius above pre-industrial levels, the press release said."

"Can Extremely Reflective White Paint Save the Planet?"

"To stabilize global temperatures, humanity needs to replace the energy basis of industrial modernity. We must build vast constellations of wind and solar farms, lace continents with high-voltage transmission lines, replace all internal combustion engines with batteries, decarbonize heavy industry, increase the energy efficiency of our buildings, expand mass transit, and promote housing density, among myriad other things. Unless we just need to dump 139 billion gallons of extremely white paint across roughly 2 percent of the Earth's surface. This week, the New York Times reported on Xiulin Ruan's extraordinary feat of pigmentary engineering. A researcher at Purdue University, Ruan has spent years trying to develop a maximally reflective type of white paint, one that could bounce upwards of 95 percent of the sun's rays off of any given surface and then back out into deep space, cooling the planet in the process. Now, Ruan's team has engineered a shade that reflects 98 percent of sunlight."
