56 number of years I've been on this planet. Please pray for me.
June 12 in Minnesota Weather History. Data: Twin Cities National Weather Service:
1991: Lightning struck a tree at the U.S. Open golf tournament in Chaska, MN. One spectator was killed, and 6 people were injured
1968: The 13 mile long path of an F5 tornado took it directly through Tracy, MN. Nine people were killed and 111 homes destroyed. Farms outside of town were swept completely away, two of which had been hit by a tornado 44 years earlier
1930: Tornado hits Northfield area, heavy damage at Randolph.
A Lazy Jet Stream
Why is my furnace on - a week before the Summer Solstice? Why are we Seattle-like, stuck in a perpetual puddle with far more rainy days than dry days? I have a pet theory, based on emerging science linked to changes in the Arctic and rapid warming up north.
Ever since the Polar Vortex treated us to a "Laura Ingalls Wilder Little House on the Prairie Winter" the jet stream has done more aimless looping and meandering than usual.
Rapid warming over the Arctic shoved polar air into the USA, knocking the jet stream out of alignment. It's still trying to get its groove back, blowing 300-500 miles farther south than normal for mid-June. Which means big temperature gradients/contrasts over the northern USA. Which, in turn, is spinning up a conga-line of unusually intense storms.
I hereby decree that the weekend starts right now (I am within my First Amendment rights!) Expect blue sky, less wind and fewer goosebumps with highs surging into the 70s.
An ill-timed warm front approaches this weekend, a magnet for T-storms packing locally heavy rain into much of next week. Another 1-3 inches of rain falling on saturated soil may spark flash floods.
Remember, I'm just the messenger.
2.41" additional rain by midday Sunday (00z NAM model).
2.5" rain predicted for the Twin Cities the next 9 days (ECMWF model).
3.53" rain predicted for KMSP over the next 16 days (GFS model).

“Electricity storage technologies have the potential to enhance emission performance by reducing the need for fossil fuel-fired EGUs [Electric Utility Generating Unit] to provide generation during periods when intermittent wind and solar generation are unavailable due to natural conditions. States may wish to consider this possibility as they consider options for design of their plans.”Translation: as solar panels and wind turbines become more attractive, batteries can store power for when the sun isn’t shining and the wind doesn’t blow. Renewables will account for about 70 percent of new generation capacity added worldwide from 2012 to 2030, according to Bloomberg New Energy Finance..."

Tesla Wants To Kill Gasoline By Sharing Its Electric Car Technology With Everyone. Here's a clip from a follow-up story from The Verge: "In an attempt to spur innovation, Tesla Motors says that it will allow anyone to use its patented technology on electric vehicles — even its biggest competitors. In a blog post, company CEO Elon Musk says that Tesla will not initiate patent lawsuits against anyone using its technology "in good faith." He's made this decision in part because the electric vehicle landscape is so limited right now, with these vehicles representing less than one percent of major automakers' sales. Musk also believes that the current patent system often serves to stifle innovation and bolster large corporations, rather than helping out individual inventors..."
