My hunch/2cents, is if it holds together, it will bow out. Chicago area might have another derecho on its way.

Judging by radar, and as tony mentioned about seeing some rapid acceleration ahead.

I could be very wrong, thought I add my 2 cents.

Definitely starting to "surge/bow" in two segments - one that just moved through Stevens Point, and one near Wisconsin Rapids.

If this is another Chicago-Milwaukee special, that will be our third or fourth one this year. Pretty rare to have 3 high wind thunderstorm events that pretty much traverse the same territory. Shouldn't forget about Madison and Rockford, as they would likely get hit as well if this thing maintains.

Winner winner chicken dinner.

There might be a rear-inflow notch forming this thing in Wood County. Too early to tell for sure yet but something to watch.

Just noticed that.

As mentioned before, there looks to possibly be a broad developing MCV moving through Portage Co.

Certainly has that look to it. It's also a pain that the MCS is now paralleling the radials from ARX, makes the base velocity interrogation difficult.

Once/if the rear inflow jet gets fully established it will likely help accelerate it as that should aid the upscale growth/forward propagation. This is a far cry from the crap we saw last night in central Wisconsin.

Absolutely. This thing should have staying power.

Irony much? When did you leave? Right before this?

We left there at 5. I think half the MW is in the dells trying to stay cool.. no fun waiting in line for a hr so spent the day in the lazy rivers and wave pools just people watching and chillin...all walks of life I tell ya.

I haven't been on following the thread but radar looks better than last nights at least.. Hows this line gonna move do you think? continue se or will it split and miss us lol.

Yeah the WAA wing is very subtle, but there. Just west of there west of Wautoma there appears to be an area of enhanced winds. The MKE radar is showing 75kts+ at 9000'.

EDIT: typing too fast FTL

That's a nice RIJ aloft, and the potential boundary interaction with the remnant lake breeze is intriguing.

I don't see it splitting. The most likely way it would miss is if the back end swings around so it is aligned n-s, and then swing e and miss us just to the north (or it could fall apart totally, but that's not likely). I think we have a 50% chance or so of seeing the thunderstorms along the leading edge. It's still moving relatively slow so it probably won't arrive until 2 if it does. Unfortunately, I will have to miss it b/c I'm planning on golfing in the 90+ heat tomorrow.:arrowhead:

Thanks for that post.. Man I hope you're golfing early! (Sounds like it) Freeze some water bottles up to take with ya. Carting it or walking? couldn't get me to walk it unless we were golfing with the birds chirping 1st thing in the AM.

Sun kicked my tail.. dunno if I can make it awake to see what happens either.. I'm sure if i lay down my euro alarm clock will wake me up tho.

I came up with a little pathcast for the MCS overnight. It hinges on three ideas. A) The MCS holds together. B) The MCS follows the theta-e gradient. C) The MCS moves about 40kt. That last one may be a bit bullish right now, but may end up being too conservative if this thing really takes off.

Nice RIJ pushing through Waushara and Marquette Counties...and soon Green Lake, Winnebago, and Fond Du Lac Counties.

Also, it's pretty clear there is an MCV now.

Looks like the bow is surging towards Oshkosh and Fond Du Lac...

If that holds it's quite possible most of the action is from MKE on north.

O man that's a big weenie pointed at me. I'm scared. hopefully it gets grated apart like last night lol but I have a feeling that's not going to be the case. Thanks sooo much, Tony for your thoughts and cone.

I think it's path will actually be slightly to the left of the cone from the storm's point of view; in other words, slightly further north and east. Ozaukee County will probably take close to a direct hit from the bow. Then again, all of these are only guesses. I could see it shifting direction a couple more times.
