Drying Out - A Little Severe Storm Perspective
Yesterday was a subtle (yet blunt) reminder that, historically, June is Minnesota's wettest, most severe month of the year. Arguably the worst time for outdoor weddings and grad parties, too.
The approach of juicy, super-heated air from the south, coupled with twisting winds aloft, can create an environment where thunderstorms begin to spin. These rotating "supercells" can travel for hours, a protected updraft sparking large hail, even tornadoes.
Perspective is important: out of 100 thunderstorms only 10 will reach severe limits (58 mph plus winds and/or 1-inch diameter hail), and only 1 will ever produce a tornado.
Yesterday's weather drama is fading as a drying northwest breeze chases storms into Wisconsin today. The sun comes out later, and stays out into most of Sunday with a gradual warming trend.
ECMWF guidance hints at mid-90s Sunday with a heat index that may leave you fleeing in search of a cool body of water.
But it can always be worse. Sunday's predicted high in Phoenix is 118F, just shy of the all-time record of 122F, set on June 26, 1990. Truly gasp-worthy.
Early Count: 7 Minnesota Tornadoes. This will change as NOAA conducts site surveys, but there may have been (at least) 7 separate tornado spin-ups yesterday across southern and west central Minnesota. I suspect most of these were smaller tornadoes, EF-0 and EF-1 but I wouldn't be surprised to see swaths of greater damage. Check out the details at NOAA SPC.
You Will Never Guess What Kind of Weather is the Deadliest. Cities, with additional heat provided by the urban heat island, are most vulnerable to heat-related ailments. Here's an excerpt from weather.com: "There are a number of significant weather events that residents of this great nation have to endure every year. Given three guesses as to which one produces the greatest number of fatalities, what would your answer be? Violent winds from a hurricane or tornado, lightning from thunderstorms, and rising floodwaters come to mind. But the weather event that actually produces the greatest number of fatalities is heat..."

Hottest Days on Record in Phoenix. Feel free to forward this to a friend in Scottsdale. 120F looks increasingly likely (air temperature) Sunday afternoon. Like Venus, with drive-thru restaurants. Graphic credit: AerisWeather.

Save the Climate and Protect America: Build an "Underground Energy Interstate" Now. I found an Op-Ed at Capital Weather Gang fairly convincing; here's the intro: "The two greatest threats the United States (and other nations) face could be solved by a single infrastructure project that could be done now with existing technology. The threat the Democrats see is climate change. The threat the Republicans see is terrorism on a massive scale. There are weapons, called Electromagnetic Pulse (EMP) nuclear bombs, currently in the hands of nations such as North Korea that could be in the hands of terrorists in 15 years. An EMP bomb placed high above Kansas City, Kan., could wipe out the U.S. electric system and much of our digital electronics..."

In an analysis last year, the NPCA found that even parks with the most protection under the Clear Air Act—icons like Mesa Verde, Everglades, Yosemite, Acadia and Sequoia—continue to experience pollution that can affect wildlife and human health, as well as the climate. According to the National Park Service’s own data, ozone levels on the peaks of the Great Smoky Mountains, for example, are nearly twice those in nearby cities like Atlanta. Up to 90 percent of black cherry trees in the park (depending on location) have sickly yellow leaves and other signs of ozone damage, and visitors with asthma can have trouble breathing. In California, Sequoia and Kings Canyon national parks regularly have ozone pollution that exceeds the 70 parts per billion standard set by the Environmental Protection Agency..."
Cheaper coal and cheaper gas will not derail the transformation and decarbonisation of the world’s power systems. By 2040, zero-emission energy sources will make up 60% of installed capacity. Wind and solar will account for 64% of the 8.6TW [1 Terawatt = 1,000 Gigawatts] of new power generating capacity added worldwide over the next 25 years, and for almost 60% of the $11.4 trillion invested.File photo credit: Shutterstock.

Its presence loomed larger this year, as 65 percent of survey respondents reported being concerned about the potential impact of climate change and rising sea levels on the real-estate market. According to the survey, buyers did not share the sentiment; only 22 percent mentioned it as an issue.Image credit: Miami Herald.
