Severe Storms

Today looked like it would be just a rainy day for most of Minnesota, tornadoes were very unlikely it seemed.  At 12:51pm I noticed the velocity image below and found it very odd to see.  Looking at the radar location and the couplet it is clearly rotation 2 miles S of Watertown, MN.  Had no idea that an hour or so later a tornado would develop in Downtown Minneapolis.  Today looks to be an outbreak day with more then 12 tornadoes seeming likely for the Midwest.

Velocity showing a couplet (little notch) just south of Watertown, was likely rotation. (Time was 12:51pm)	This is just an amazing look at the rotation at the time the tornado touched down.
This was the cell that would go on to produce the tornadoes in Brown County and I let it go south.	To my NW I had this area of rotation that I decided to chase instead.

Wall cloud to my NW of Olivia some ways, honestly I got lost for a bit today.	Another look as it get completely rain wrapped
Weird inflow maybe lowering to my west which was pretty cool.	Every direction the skies just started to open up with rain shafts.

Front of the storm to my north which I just could not look away from.  Reminded me of  what a storms skeleton would look like.
Last look at the this skeleton of a storm.

Base of a storm with some strong inflow.	Was pretty interesting and likely a lowering forming but the rain to my west was on the doorstep.
Feature to the south of Olivia and the rain to my west.  Looks like either a shelf or updraft region of the storm.  Strange day that is all I know.
