Strong T-storms (warnings far southeast Minnesota)
May 29, 2013 — 3:00pm
Starting To Pop. I still think the greatest potential for severe storms will be over far southeastern Minnesota and western Wisconsin into the evening hours - dynamics aloft are most ripe for hail and damaging winds in this area. A few strong storms are pushing into the MSP metro area, capable of pea-size hail and downpours capable of urban and small stream flooding. NWS Doppler at 3 pm. Here's the latest warning:

We've lost 2 1/2 hours of daylight and about 4 degrees off our average high temperature; the sun now as high in the sky as it was in mid-April. No hot fronts are brewing, but today will feel like July; more 80s likely next week. The arrival of cooler air sets off a few T-storms late tonight, but Thursday there will be no doubt in your mind that the atmosphere is shifting gears. More downpours by Sunday? Well, at least the pattern is consistent...
After a less-than-optimal Saturday yesterday restored my faith in a Minnesota August. At the risk of editorializing, it was perfect. A gusty south wind tugs the mercury well into the 80s today and Tuesday; another squall line of heavy T-storms late Tuesday night into early Wednesday marks the leading edge of cooler, drier air. A few T-showers may sprout again by the weekend. I know, what a shock.
Good news on the weather front: today will be even nicer than yesterday! At least we salvage one day of the weekend. With any luck we can dry out a little as we head into the Minnesota State Fair and Labor Day. The maps still look more like June than August.
If you liked Friday you will adore today with gusty northwest winds, off and on showers and temperatures stranded in the 60s. Not a great lake day, but it won't slow too many of us down. Sunday looks brighter, drier and milder after a chilly start. No, it's not quite time to dig out the jackets, not yet. Meanwhile the GFS is pulling a big hurricane into the southeastern USA by late August. We'll see.
The atmosphere is shifting gears - the first real taste of autumn is brewing for the weekend, and this surge of cool air spins up a storm capable of dropping 1-3" of additional rain today into Saturday night. Just when you thought it couldn't get any wetter. Saturday looks windy, cool, wet and foul - Sunday looks better, and it should feel like summer again by early next week.
