Storm risk increases; flash flooding possible in 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.

With any luck we'll escape another day of hail and high water. Yesterday's troublesome storm in the upper atmosphere pinwheels away, a more stable sky overhead should mean sunshine, and no weather drama later today. Temperatures still trend cooler than average into next week. Real summer heat is on indefinite hold.
All things considered it was a pretty good weekend. Except for the downpours late in the day Sunday with heavy weather approaching from the north. The same upper air low sparks more late-day thundershowers today. More events will be delayed, postponed and cancelled. Which brings up some steps you can do to be more weather-aware during thunderstorm season. It's all about trying to make consistently smarter choices. Are we still talking about weather?
I hope you were able to salvage your Saturday plans - it turned out to be a fine day, and the heaviest nighttime T-storms skirted the metro, dropping some 1-2"+ amounts on the southern suburbs. We get off to a promising start again today but the atmosphere remains unstable; capable of more PM showers and T-storms. The heat wave gripping the west is forecast to stay there - once again weather systems appear to be stuck.
