Holy convective contamination on that forecast sounding.  

Can you explain? Is it the the red bars on the left? There's soundings within a few miles without them but everything else about the same. Some things on soundings I'm still learning about.

Yeah, the bars represent omega.  Pretty strong/deep lift at that location at that time.  You can get enhanced soundings (wind profiles) that may not be representative of conditions across the area.  

Can you post one without so much omega?  Would be curious to see how those wind profiles look.

I switched out the sounding in the opening post for you to look at.

Tor warning now for Lake County Illinois and confirmed tornado in Michigan.

It looks like no tornado was confirmed after all. This is why I'm not a fan of "radar confirmed" language in warnings like the one last night. 

Also not a fan of "law enforcement confirmed," as we learned during the most recent tor warning in Van Wert, OH. Turned out no one saw it, they just THOUGHT they saw it.

In the Emergency Management world, we call them Sheriffnadoes.  Law enforcement would make great eyes in the sky to supplement our spotters/chasers since they are already mobile, but they won't come to any trainings to know what to look for. They seem to have the mindset of "I don't need training, I already know everything I need to know about weather." This happens waaaayy too often. It causes the public to have lower confidence in our legitimate reports.

It's iffy this far east but if a storm can go this afternoon, it could be a little interesting near that warm front.

You and I are due for something to roll through. Were you able to at least see the light show to the north last night?

I've had a met tell me that "radar confirmed" meant that a tornado was actually there whereas "radar indicated" meant only rotation was observed.  It does get confusing.
