Since May 15: Second Driest On Record at MSP
By Paul Douglas

I don't take a blue-sky summer day for granted anymore. And it's no wonder we're being invaded by plumes of dirty air snaking southward out of Canada. At last report there were 880 fires from Quebec to British Columbia, 580 of those blazing out of control. I suspect smoke will be a sputtering nuisance into autumn, along with drought.

Meteorological summer (since June 1) is the 3rd driest on record. Since May 15 in the Twin Cities it's been the second driest on record. Only 1988 was drier.

The extremes are trending more extreme over time, and the old adage is true: only in Minnesota can you be knee-deep in mud with dust blowing in your face! We interrupt this drought for a slight severe storm risk later today. A few cells may drop ping pong size hail. A few scrawny storms may bubble up late Saturday, but I can't get excited about rain chances anytime soon. 80-degree highs give way to some 90s next week. Mid to upper 90s are possible the latter half of next week. 90.3" snow, followed by a real summer eh?

Extended Forecast

WEDNESDAY: Some sun, severe T-storms? Winds: SW 10-20. High: 87.

WEDNESDAY NIGHT: Chance of t-showers early, then clearing. Winds: WNW 10-15. Low: 64.

FRIDAY: Sunny, winds ease. Winds: NW 7-12. Wake-up: 63. High 85.

SATURDAY: Hazy sun, few T-storms nearby. Winds: W 7-12. Wake-up: 67. High: 87.

SUNDAY: Sunny and hot. Winds: NW 7-12. Wake-up: 66. High: 89.

MONDAY: Warm sunshine. Winds: S 5-10. Wake-up: 64. High: 86.

TUESDAY: Mostly sunny, partly-sweaty. Winds: SE 7-12. Wake-up: 67. High 87.

Climate Stories

(NOAA/The Minnesota Star Tribune)

"What this year's El Nino means for wheat and global food supply"

The World Meteorological Organisation has declared the onset of the first El Nino event in seven years. It estimates 90 per cent probability the climatic phenomenon, involving an unusual warming of the Pacific Ocean, will develop through 2023, and be of moderate strength. El Nino events bring hotter, drier weather to places such as Brazil, Australia and Indonesia, increasing the risk of wildfires and drought. Elsewhere, such as Peru and Ecuador, it increases rain, leading to floods. The effects are sometimes described as a preview of "the new normal" in the wake of human-forced climate change. Of particular concern is the effect on agricultural production, and thereby the price of food - particularly "breadbasket" staples such as wheat, maize and rice. El Nino's global impacts are complex and multifaceted. It can potentially impact the lives of the majority of the world's population.

"The heat wave scorching the US is a self-perpetuating monster"

"Just weeks after a third of the US population was hit with air-quality alerts thanks to smoke from climate-change-fueled fires in Canada, 100 million Americans are now under heat alerts. A cap of extra-hot air, known as a heat dome, has settled over the West and South, pushing temperatures relentlessly higher. The map below shows excessive heat warnings in purple and heat advisories in orange, and the forecast is that things will get worse through the weekend. Highs will stay above 110° Fahrenheit in Phoenix; California's Death Valley is flirting with 130°; and Texas' grid is struggling to keep the AC on. This follows the hottest June on record globally. "With an evolving El Niño event, that is certain to further increase global temperatures," says Howard Diamond, climate science program manager at the National Oceanic and Atmospheric Administration's Air Resources Laboratory. (El Niño is a band of warm water that develops in the Pacific Ocean and influences weather around the world.) "Canada has also experienced multiple bouts of prolonged heat this summer, contributing to the worst wildfire season the country has ever seen," Diamond adds."

"'Cannibal' coronal mass ejection that devoured 'dark eruption' from sun will smash into Earth on July 18"

"Two coronal mass ejections have combined into an enormous cloud of magnetized plasma that is forecast to hit Earth on Tuesday and potentially trigger a strong geomagnetic storm. A "cannibal" coronal mass ejection birthed from multiple solar storms, including a surprise "dark eruption," is currently on a collision course with Earth and could trigger a sizable geomagnetic storm on our planet when it hits on Tuesday (July 18). Coronal mass ejections (CMEs) are large, fast-moving clouds of magnetized plasma and solar radiation that occasionally get flung into space alongside solar flares — powerful explosions on the sun's surface that are triggered when horseshoe-shaped loops of plasma located near sunspots snap in half like an overstretched elastic band. If CMEs smash into Earth, they can cause geomagnetic storms — disturbances in our planet's magnetic field — that can trigger partial radio blackouts and produce vibrant aurora displays much farther away from Earth's magnetic poles than normal."
