For those of you who share my fascination with the weather, there was a really cool phenomena Friday morning and I thought I'd share.

First off, Friday had a bunch of stuff going on from flood warnings, to squall lines and even a wake low but it also had something called a "Mesoscale Convective Vortex"!

It's essentially just a mid-level low that gets cooked up by a large complex of thunderstorms but with an MCV, the circulations doesn't read the ground level.

You see, storms release huge amounts of energy and that can add heat to the mid atmosphere and then boom you have these little lows. They're common but not always easy to see on a satellite image. Sometimes you can see them when the thunderstorms dissipate.

It looks like a little swirl or spiral on the satellite picture.

If an untrained eye saw it on a visible satellite loop it would be understandable to think it was a mini hurricane something but it's something that actually happens a lot in the summer but Friday's was interesting because it was an extreme example. They're usually not as large and not as easy to spot.

Below is a map from the local NWS office that shows the weather features that were present around 11:45 AM and then on top of that is the visible satellite image from the same time. Tell me that's not cool! Weather Geeks say BLEEP! :-)

BLEEP!

Geeky, but very cool stuff.

Do Canadian weather geeks say "BLEEP-eh?"

Sorry Rob, I couldn't resist.

Rob and Vince-

I saw that on the map and I thought I had clicked on the wrong part of the NWS! I seriously had the thought, "what a shabby looking hurricane!" I tried to find a name for that sort of phenomenon. but I couldn't. Thanks for the lesson! :)

Interesting photos. Now if only the stationary front can move a little south, that would be great. Maybe I can do a dance or something and see that if works.

A long, long, time ago in a farmers field far, far away, Rob noticed a change in the wind and became fascinated with the weather. Why you ask? (Pause for you to say "why?") Well, it was at that moment he realized he was downwind of the manure pile on the turkey farm where he grew up! After that he watched the weather very carefully in an effort to save his sense of smell! Okay, that's not entirely true but I did grow up on a turkey farm and I have been fascinated with weather and broadcasting for quite some time. I began my career in radio before making the jump to TV. I worked on Good Morning Toronto. After that, I decided to pursue my dream of living and working in the U.S. and joined Wake Up Rochester in Rochester NY. I spent three years in "Bills Country" before coming to my senses and moving to "Packer-Town!" (GO PACK!) I also spent some time trying to make it big as a comic actor and studied the art of improvisation at Toronto's Second City Theatre with teachers like SCTV's Joe Flaherty! I moved here with my beautiful wife, Tanya, who's the real comedian in the family, my son Noah, who's giving my wife a run for the title of funniest Haswell and my daughter Nyla who is the cutest 2 feet of human being you could ever meet! We're very excited to be living in the great city of Milwaukee and we're looking forward to learning all there is to know about Wisconsin! By the way, where do you buy those cheesehead hats anyway?
