I wish Mother Nature would friend me. Hey, I "like" every kind of weather she throws at me, even the assorted atmospheric atrocities I didn't have the foresight to predict, in advance. Sure, the toys (um technology) are great. Maps, charts, flashing red Doppler blobs. Guys like shiny things.
But there's something fundamentally democratic about weather; it impacts everyone. Rain falls on the righteous and sinners alike. We have the illusion of control over parts of our lives, but when it comes to the elements we're all bewildered spectators. And tornadoes? A dark and deadly Lotto. Despite super-turbo-bipolar-Doppler we still can't predict where they'll drop out of the sky.
God's revenge for Jerry Springer? No, just a reminder that we live in a random, often violent world.
Saturday was a blunt reminder that even downtown St. Paul can get pelted with ping-pong size hail. A magic Monday gives way to 80s by midweek. The best chance of T-storms: Thursday, again Saturday.
Never underestimate the gravitational pull of storms to major summer holidays. A hot front may push the mercury into the 90s by Sunday (best day for the lake?) but a thundery front returns for Memorial Day.
