May and June Are Peak Tornado Months
An unstable sky may spark a few T-storms later today, in fact, the entire week looks partly thundery, with rising dewpoints. Summer stickiness arrives later this week with the best chance of showers/T-storms for Saturday's Fishing Opener. I'm shocked. Check the blog for more details. -Todd Nelson

May and June Are Peak Tornado Months
Paul Douglas
There has never been an F6, an "inconceivable" tornado with winds over 318 mph, but the wedge tornado that struck the suburbs of Oklahoma City May 3, 1999 came close. A Doppler on Wheels (DOW) measured winds of 302 mph, the strongest ever observed on Earth.
Unless you have a basement, surviving such a violent tornado is unlikely. Minnesota experiences an average of 29 tornadoes every year, but 2010 brought 113 - the most in the USA.
Twisters are rare, but there is nothing stopping a large, violent tornado from striking the MSP metro. We've been lucky since the May 6, 1965 super-outbreak. A basement under the stairs or a small, windowless interior room offers the greatest protection. Do NOT seek shelter under a bridge overpass, where winds can actually be stronger.
An unstable sky may spark a few T-storms later today, in fact, the entire week looks partly thundery, with rising dewpoints. Summer stickiness arrives later this week with the best chance of showers/T-storms for Saturday's Fishing Opener. I'm shocked.

Climate Stories
"Arctic sea ice loss and fierce storms leave Kivalina Search and Rescue fighting to protect their island from climate disasters"
"As winds and waves from Typhoon Merbok devastated communities along the coast of Western Alaska in 2022, Reppi Swan Sr.'s phone began to ring at Kivalina, a barrier island 80 miles above the Arctic Circle. A neighboring family had lost 3 feet of land to the rumbling lagoon, and their home was now sitting just 6 feet from the angry water's edge. Reppi called his brother Joe Swan Jr. and quickly slid into his insulated rain gear. As a volunteer first responder, Reppi plans for emergencies like this. He and his wife, Dolly, had been patrolling the island for dangerous erosion every few hours during the storm. To prepare, he had already inspected the city's heavy equipment and located a pile of boulders left over from a recent construction project."
"COP28 negotiating positions emerge during talks in Germany"
"At a gathering of representatives from 40 nations in Berlin, early jockeying for negotiating positions is already proving insightful ahead of the next United Nations climate summit in Dubai later this year. Why it matters: At the Petersberg Climate Dialogue, a forum held at the German Foreign Ministry, key players in climate talks are laying out their priorities. They are also getting to know Sultan Al Jaber, the United Arab Emirates' president designate of COP28. The big picture: The Petersberg dialogue kicks off an accelerating pace of meetings to set the agenda for COP28, which begins in Dubai on Nov. 30. The informal setting is designed to allow for the free exchange of views, with more discussions to come Wednesday. Zoom in: After facing staunch resistance to calls for a fossil fuel phase-out during the climate talks in Glasgow and Sharm El-Sheikh, Germany and the European Union are aiming to unite the world around goals to triple the use of renewable energy sources."
"Is this the beginning of the end for gasoline?"
"The United States is by far the world's largest consumer of gasoline. But consumption has fallen compared with pre-pandemic levels, and it's plausible that the U.S. has passed its peak gasoline use. Explore the interactive graphic below to see how gasoline consumption has changed over time. This graph shows the amount of gasoline consumed in the U.S. The dotted line at the end is the expected gasoline use over the coming two years. The data is from the Energy Information Administration. Driving and gasoline use peak in the summer and hit their annual low point in January. The COVID-19 pandemic disrupted everything, including driving habits and the gasoline supply chain. The sharp dip in gasoline use in March 2020 occurred when many Americans stopped driving to work, school, and most other places. Beginning in January 2022, gasoline consumption resumed the same seasonal pattern as before the pandemic, but at a lower level."
