Flash flooding, severe storms remain a threat across southern Minnesota on Monday

Rain ends around midday, with stronger storms possible later Monday.

Southern Minnesota is under the gun again Monday for heavy rain and possibly another line of storms that could bring more strong winds and large hail late in the day. 

Multiple rounds of heavy rain from strong and severe storms have already saturated the ground, and with another 2-4 inches possible today the weather service has placed the south metro and areas west and south in a flash flood watch through noon Monday

"Thunderstorms capable of producing heavy rain are expected to continue through the night from western Minnesota into southeast Minnesota and west-central Wisconsin. Areas of 2-4 inches of rain have already fallen from thunderstorms earlier today and tonight across this area. Thunderstorms training over the same areas could produce another 2-4 inches of rain in a short period of time, leading to flash flooding."

Here's a map showing where flooding could become a concern, although it should be noted that Hennepin and Ramsey counties are not included in the flash flood watch. 


In a nutshell, widespread showers with isolated pockets of heavy rain will continue through midday. 

Then, there remains potential for another line of strong to severe storms to push through southern Minnesota late in the day. Those storms could produce isolated large hail and damaging wind, just as the storms did late Sunday night in the south metro and southeast Minnesota. 

The National Weather Service in the Twin Cities that the storms late in the day could be similar to the MCS (mesoscale convective system) that plowed through the south metro into southeast Minnesota late Sunday night. Those storms intensified just before midnight, bringing 60-80 mph winds to the south metro. 

With that, the Storm Prediction Center has an ongoing slight risk of severe storms for southern Minnesota.
