Storm Risk Increases This Afternoon - Flash Flood Risk Central Minnesota
May 31, 2014 — 3:21pm
Growing Shower and Thunderstorm Risk. The line of showers and storms that has hovered over southwest, central and northeastern Minnesoeta much of the day continues to creep east, pushing a ripe environment for pop-up showers and heavier T-stoms into the metro area. The risk of hit-or-miss storms increases as the afternoon goes on, the best chance of a few downpours western and northern suburbs. After peaking in the mid-80s today I suspect Sunday will be cloudier with more numerous showers/storms as the front passes overhead. NWS Doppler radar at 12:26 PM.
* the area outlined in green from Olivia and St. Cloud to Mora and Duluth is under a mesoscale precipitation discussion - conditions are ripe for thunderstorms with rain falling at the rate of 1-2"/hour, capable of street and small stream flooding.
A Troubled Front. 1 km visible imagery at 12:30 PM shows cells mushrooming in the warm sector (with dew points in the mid and upper 60s providing plenty of fresh fuel). Winds aloft are light - the risk of severe storms is small, but there's a greater threat of repeated ("training") thunderstorms dropping some 2-5" rainfall amounts, especially over central Minnesota.

A devastating ice event will wrap up in the Central U.S. early this week. Widespread half to near three-quarter inch ice tallies have left parts of Kansas, Oklahoma and Nebraska in a real mess. That same storm grazes southern Minnesota with a light wintry mix late Monday into early Tuesday. An icy, slushy coating may be possible across parts of southern Minnesota just in time for the Tuesday morning commute. Check the blog for more details. -Todd Nelson
If you're an outdoor winter enthusiast, do anything you can to get outside and enjoy it Sunday! Fresh snow, sunshine and near average temps will make this one of the nicest winter days of the season. A wintry mix moves in Monday and a major snow moves in this week. Check the blog for more details. -Todd Nelson
Here in Minnesota are expectations are reasonable, some would say laughably low when it comes to weather. Especially in January, when we're all deliriously happy when our teeth aren't chattering. A thaw is still coming next week, preceded by a slushy, icy concoction Monday and Tuesday. 40F isn't out of the question by late next week. In Minnesota, in mid-January, we call that a meteorological miracle...
And here it is, the reason so many American's eyes get big when pondering what Minnesota is like in January. "How do you live out there?" Well, I hold my breath a lot and try not to lick metal objects "What does it feel like?" Like being dipped headfirst in a mild form of acid - a slight burning sensation that makes you want to check and see if you still have all your fingers and toes. Then again I've been more uncomfortable at grade school assemblies, and any cold sting won't last nearly as long. 30s return next week, the atmosphere warm enough for a light mix by Monday and Tuesday. We keep oscillating between subzero and March temperatures with rain. Odd, to say the least.
More fun on the highways Wednesday; amazing what 2" of snow can do at 10 degrees. Less drama expected today, but Friday morning should see the coldest temperatures since December 18. We warm up next week, an extended string of days at or above freezing. 40F is not entirely out of the question. Oh how far we've fallen...
