Update 4:20pm: It's not time to let any guard down for sure, but there are a lot of debris clouds which seem to be limiting supercell development. The cells that are forming right now are more "showery" rather than large discrete supercells. There are still plenty of "dynamics" such as lift and shear that may overcome the lack of surface heating caused by the debris clouds. Stay tuned to see how this develops over the next 90 minutes.
Update 4pm: Twin Cities now included in latest tornado watch issued until 10pm. Follow watches and warnings and storm reports here.

Here we go again.
After torrential rains caused flooding last night in and around the Twin Cities, another severe weather day is underway. Severe storms will move through southwest Minnesota this afternoon and head for the Twin Cities area by about 6pm tonight.
A warm front is draped close to the Twin Cities today, and storms will move northeast along the front. Large hail, damaging winds and tornadoes are possible with the stronger storms today. Keep an eye out for severe weather approaching from the west and southwest.
