March 28, 1924: A drought was broken in Southern Minnesota with style as 25 inches of snow fell.
"People don't notice whether it's winter or summer when they're happy" wrote Anton Chekhov. Apparently Anton never hung out in Minnesota, where, when we discuss the day's weather, we often smile through gritted teeth. Late March in Minnesota is boom-bust, all or nothing, the beauty and the beast. Anything goes.
Exhibit A, tomorrow's date in 1924: eleven inches of snow swamped the Twin Cities. In 1969 the mercury sank to -5F. But 1986 brought a hot front with a record 83 degrees. All on the same date in late March. Throw in river flooding and occasional March tornadoes and now you know why meteorologists are cross-eyed this time of year.
Nothing quite that extreme is brewing anytime soon, I'm happy to report. The greater the swing in temperature the faster the wind has to blow to keep the atmosphere in an uneasy state of equilibrium. Translation: windy today as temperatures recover from a chilling rerun of February. 50s return Sunday; a few are 60s likely next week - punctuated by a midweek rumble of thunder. Cooler weather returns late next week - keep a jacket handy.
With most of Minnesota in moderate drought there will be no whining about rainy days.
Let it rain. Please.

Tropics Getting Warmer: Sign of Warming Times? Discovery News has the research, which mirrors what we're seeing in northern latitudes: fewer storms during the warm months, but the storms that do form tend to be larger with more intense rainfall: "...Tan's group, along with NASA, published the study. Thunderstorms play a key role in tropical weather. Thought they occur just 5 percent of the time, researchers said, they account for about half of the rainfall in the tropics. "What we are seeing is more big and organized storms and fewer small and disorganized storms," Tan said..."
