Chase Case #7

[Marc Austin]

Here we go with another interesting chase scenario! I've included the 00Z outlook from the previous day to give you all a heads up, considering you would most likely look at data the night before you choose to go chasing. Some of you may recognize this event before all is said and done. I think it still presents a forecasting challenge, so I thought it would be a good exercise.

Here's the first set of data. I won't post 18Z graphics until tomorrow in the late afternoon, so take your time choosing the best target. Good luck and happy chasing!

Edit: I'm sorry for those of you who already saw the date, this won't really be of any use to you, but I have updated the case and now there are no signs of which day this is. Some users requested I keep the case going, so I'm going to for their benefit. If you don't plan on participating, please hold comments on the results of the chase until it is over. Thanks and sorry again for the "rookie" mistakes!

Marc,

You might want to take the date off the High Plains satellite image.

 

[Verne Carlson]

Awesome Marc - thanks for starting another. I made the overnight trip from Denver to AMA and looking at the morning data.. Nice neg tilt trough with some diffluence aloft over w OK. dryline is through the central panhandles, may mix east a little bit during the day. Clearing west of Woodward, OK to Childress, TX. Target for today: Woodward, OK

Edit: I saw the date - I'm DQ'ed now.

 

[Justin Teague]

I actually chased this day... I know this because like Donald, I see the date on the 12z surface chart! ;-)

 

[Andrea Griffa]

That's fine! Another chase case!
Ok, I start from Greensburg,Ks and I wait for 18Z update to see how is going with that nuclear cap

Ooopps,I didn't see it! Too bad, because that was a very interesting chasing day.

 

[Michael O'Keeffe]

I think I'm out. Saw the date, but I'd still start near Wichita had I not seen that.

 

[Chris Allington]

Not participating since I saw the date and happened to be looking at a couple peoples old pictures from the day when I was bored at work a couple nights ago.

 

[Kurt Hulst]

Agreed with Michael O'Keeffe, I would of started in Wichita, KS. Maybe a new chase case needs to be developed.

 

[Dann Cianca]

I think I'll stick close to home on this one and head out I-70 to about Burlington, Colorado. I like the upper level support (divergence) and the directional shear. I want to stick close to the edge of the low clouds and hope to see some action on the differential heating.

 

[mikegeukes]

Saw the date, will not participate.

 

[Scott Weberpal]

You should make the date disappear like the tornadic supercell that disappeared magically that day!

The date is visible on some of the images and all of the URL's...

 

[Dann Cianca]

Am I the only one that didn't see the date?

 

[Paul Austin]

Too bad. That was actually a very interesting day. A lot of chasers might have opted not to chase that day (if you had to travel and decided ahead of time) and kicked themselves later for blowing it off. This was actually the day before we left on our Chasecastion that year. We were a little bummed at the timing. We certainly would have chased, had we been out in the plains.

Nice try, Marc. Sorry it didn't work out. I know it probably took a lot of time to put together. Hopefully you won't miss the details next time.

 

[Mike Peregrine]

Yeah, don't worry about it and thanks for putting it together, Marc!!

This was a very interesting day from a chaser perspective. My biggest memories this day ...

That satellite image tells a lot ... the cloud cover to the east of the warm sector was dense. It was foggy, very low visibility. In the time I drove a short 30 mile stretch, the sun came out, dewpoints came up and instability rose. Barely made it in time for the show ... watched as the storm of the day spun up and disappeared into clear blue sky. Scratched my head thinking "where did it go???" I still think it was the weirdest thing I've seen on a chase. Tornado to blue sky in about 15 minutes.

The date thing is no biggie ... it's impossible to catch all that stuff.
