05/08/04 NOW: NE, IA, MT, SD, ND

[Mike Peregrine]

Going to end up as a lot of elevated hail-producers, looks like even back into NW IA and NE Neb - I could be wrong ... as I so frequently am ... but looks like for the most part they're feeding off of mid-levels rather than reaching for the surface -

Of course, after just saying this I see that there are three mesos showing up in Iowa - ha - shows how much I know!

 

[Mike Peregrine]

Here's a grab from Mike's storm at 6:01 for him to look at when he gets back ... it looks to have propagated further south, which may be a good thing ... he may end up not far from home -

Waterloo Area...junkus

Shoot, the storms just really junked out west of Waterloo. Possibly the big anvil blow-off is really limiting heating of what is left.

The big storm between Dennison and Ames looks interesting with it moving south and taking on a kidney bean appearance. I wonder also if that storm and the rest are undercut by outflow? If thats the case then the tornado threat is over.

Undercut Storms !!

Just looked at Des Moines radar, and I think I see an outflow boundary out the big storms near west northwest of DSM. I think she is over gentleman!! at least for any Tornado threat.

We seriously need a decent setup soon or we're going to see chasers start heading for high ledges - - - I'll jump first - - - the weather down here was so "pleasant" today ... UGH

 

[Fritz Kruse]

Tornado Threat Not Over?

Jeez...as soon as I post the storms do opposite :roll:

Now, the supercell with a Tornado Warning west of Des Moines seems to be holding on to its outflow boundary?? So still waiting for some storm chaser reports. Apparently a tornado was reported by cops.

A case of High CAPE and low shear??

 

[Mike Peregrine]

Well, that cell and the ones back to the west certainly all appear HPish ... likely a combination of factors ... I'm guessing it's as you mention ... the CAPE/shear ratio and the LFC/LCL conditions - I still wouldn't be at all surprised if Mike came back with something from that cell northeast of Columbus ...

 

[Mike Peregrine]

Won't be surprised a bit - LOL

Keep it up Mike and Fritz, you're like play by play, but the storms are listening to your instructions. lol

 

[Mike Peregrine]

Here's the current base reflectivity from it:

Radial velocity looks like about 20 kts inbound by about 10-20 outbound on it - - - hard to tell -

 

[Dan Cook]

Tornado warning out for Colfax county in NE Nebraska until 8.

 

[Mike Peregrine]

Number one reason to bruise your own leg kicking yourself:

Hey How about ME???

Hey Mike,

You should be in my place in Lincoln NE. My wife and daughter went on a afternoon trip to Hastings. They are on their way home (in town at this hour) and should be back home safely. The problem is they took both the video and digital cameras with them. Otherwise I would have taken both and headed out to Columbus NE to catch some storm pics. But I had to watch the home front and keep our two Bichon Freess dogs out of trouble...

Looks like both Lincoln and Omaha, particularly the latter will catch the brunt of this storm line, which is moving slowly (10 mph) to the E-SE. Last TW was for Butler county which is E-SE of Columbus NE.

Hope you chasers are getting some great photos!!! 8) LJK.

 

[David Draun]

Not in the targeted area, but NW of Chicago is begining to act up. First a small storm went up and orphaned its anvil. Now, several cells are begining to EXPLODE across N central IL. Plenty of lightning to my west. Radar is lighting up :shock: I'm thinking the next MD/WW will be here.

 

[Mike Peregrine]

Well I went for a jog to clear my head and it felt good - plus, on the way my weather radio went off with a svr watch ... even though I'm on the low end of it, it still sounded nice - - -

And you know what I'm thinking about tomorrow now ...

OUTFLOW BOUNDARIES!
