It’s that time of year again for fall colors and the MN DNR has its fall color detector up and running. Much of the state is still colorless, but there are a few colors showing up here and there.

“The mist comes on little cat feet. It sits gazing at harbor and city on silent haunches and then passes,” wrote Robert Frost, a gifted poet. Not a meteorologist with a made-up name. Just to be clear.
September is foggy season in Minnesota. The nights are as long as they were in March, but the summer humidity persists, creating a weather recipe for “lazy clouds”. Clear skies and light winds allow the temperature to drop to the dew point, causing clouds to form at ground level.
Another summer heat surge kicks off the mid 80s today with some scattered T-storms possible. A strong northwest wind treats us to 60s on Wednesday, and outer suburbs can wake up to 40s on Thursday and Friday morning. No gel yet, but I’ve just dragged a few sweatshirts into my closet, just in case. Yes, our T-shirt days are numbered.

In Utah, the drying up of the Great Salt Lake is causing horrific pollution as it expels dust along with toxic chemicals like arsenic into the air. The Great Salt Lake is the largest saltwater lake in the Western Hemisphere and is drying up due to climate change and water usage in the state. The water fell to the lowest point in history. When the water dries up, remnants of the dry lake bed can be blown away by high winds and carried to nearby communities like Salt Lake City. Heavy metals like arsenic, along with calcium and sulfur, are released into the air. The Environmental Protection Agency says breathing arsenic can cause lung cancer, as well as skin, cardiovascular and neurological problems. Parts of the exposed lake bed are also contaminated with tailings from copper and silver mining.

“Deadly floods In Pakistan. scorching heat and Forest fires in the American West. Torrential rains in Australia and Indonesia. A mega-drought in Brazil and Argentina. As climate change pushing weather disasters to new extremes, it’s La Nina, an atmospheric phenomenon, that has been causing chaos since mid-2020. And now the planet is on the cusp of something that has only happened twice since 1950 – three years of La Nina. Another La Nina year means the world is racing towards $1 trillion in damage from weather disasters by the end of 2023. Floods, droughtsstorms and fires will destroy more homes, ruin more crops, further disrupt shipping, hamper energy supplies and ultimately end lives. »

“The World Meteorological Organization (WMO) predicting that the current phase of La Niña will likely continue for the next six months, making it a rare three-year-old La Niña and the first of the century. “It is exceptional to have three consecutive years with a La Niña event,” Professor Petteri Taalas, WMO Secretary General, said in a statement. While the El Niño and La Niña phases are complex weather patterns, in short, they refer to rising and falling temperatures in the eastern Pacific Ocean. The cooling phase is La Niña while the warming phase is El Niño. In an El Niño year, the warmest waters of the Pacific gather at the northern end of South America. These fluctuations in ocean temperature drive global weather events.”
