Minnesota Weather History on May 17. Courtesy: Twin Cities National Weather Service:
1980: Mt. St. Helens erupted. The smoke plume rose to 80,000 feet. The cloud circled the earth in 19 days. Brilliant sunsets were seen over Minnesota for days afterward.
1933: Tornadoes hit McLeod and Mower counties.
Everywhere I go people come up and ask me the same pained question. Is it safe? "Can I remove my driveway stakes? No more snow, right Paul?" Nervous laughter. "Is it safe to plant my annuals? Can I put my boat in without ice forming on my engine block? Is it safe to finally come out of my weather bunker?"
Although I may have said something similar in late March.
Son Of Polar Vortex shows signs of (finally!) retreating north. The jet stream buckles northward over the next 72 hours, sending a well-timed warm front surging across the Great Plains.
We should hit 70F later today; mid-70s are likely Tuesday, another string of 70s as we sail into Memorial Day weekend. Long-range ECMWF models prints out 82F on Memorial Day, which made me want to give my laptop a hug.
Don't do it. People will stare.
"But will there be complications, gangs of thunderstorms to spoil our lukewarm fun?" T-storms are likely Monday, some heavy, but a puff of slightly drier Canadian air keeps most of the action south of Minnesota Tuesday into Sunday. A few storms may pop by Memorial Day, especially up north, after daytime highs nudge 80 degrees.
Frost and jackets to shorts in 48 hours?
Only in Minnesota.
