Thanks for the values.

Is the new Euro similar in the evolution of the secondary deformation zone compared to some of the other new 00z runs?

BTW I started a trial with Accuweather Pro a few nights ago to see how the Euro looks on that, but unfortunately they run almost an hour behind even some of the free sites. Needless to say I definitely won't be paying for their service. Too bad as I really like their graphics.

I must say Im mildly excited for tomorrow night. When do you think the strongest winds will begin? Im going to go ahead and call it 2-3 inches of snow for LAF.

Much of the day should be pretty windy but I'd expect the really good stuff to kick in early and especially mid evening.

Latest runs looking a little better...broadbush 1-3" through all of central Indiana may be the way to go.

Much of the day should be pretty windy but I'd expect the really good stuff to kick in early and especially mid evening.

Latest runs looking a little better...broadbush 1-3" through all of central Indiana may be the way to go.

Ya, not often in Indiana do you get light, moderate snow to coincide with 40-60mph wind gust. Should that come to fruition it may be a bit wild for a time tomorrow night.

I noticed something a bit odd when delving into some hi res models while talking with a friend.

This is the ARW:

http://i.imgur.com/v5nOY.gif

First frame shows two low pressures as the main LP splits. One over near central IL/IN and the other over LM.

Next frame; both shoot NE.

Last frame; LP's in NW OH, and North central MI.

Apparently the NAM has something similar, but it splits somewhere different. Could this explain the new Deformation band popping up on a few of the models? And is this a fairly new thing that's recently popped up? Thanks.

Thanks for the values.

Is the new Euro similar in the evolution of the secondary deformation zone compared to some of the other new 00z runs?

BTW I started a trial with Accuweather Pro a few nights ago to see how the Euro looks on that, but unfortunately they run almost an hour behind even some of the free sites. Needless to say I definitely won't be paying for their service. Too bad as I really like their graphics.

The position is similar, but not as much QPF.

Yea, the delay is unfortunate. The good thing is text data is out right away, and I still use a few of the maps from time to time.

I agree with a broadbush of 1-3". Dynamics are definitely impressive so I wouldn't be surprised to see some isolated higher amounts, particularly along and North of a LAF-MIE line. Should be a fun system to armchair watch from Idaho ;)

Wow, a CG hit very close to this area. Definitely didn't expect that. Now, if it were only snowing. :tomato:

Based on the new guidance tonight, and the way the secondary deformation zone looks I'm bumping up my call for the QC. My original call a few nights ago was 2-4, which I dropped to 1-3 late last night through earlier today. I think 3-6" sounds pretty good. Not an extreme amount of snow, but with 50-60mph winds for at least 6hrs it's gonna be brutal.

Hell of a trowal and extended def zone setting up tomorrow on the last few RAP runs for most of IL, eastern IA/MO. Also seeing some winds inside the mixing layer that are a bit scary across that entire zone. Looks like some folks will see a sharp 20+ degree drop and a flip to blinding snow in 2-3 hours. Could see a thin, forced line of convection right on the cold front as well (to the west/north of the current rumbler action).

On a personal note, I've been getting pretty consistent rolling thunder all night. With that and the wind, I could easily mistake this for a late spring night MCS.

A much respected local TV met posted this update a little while ago on his FB page. Gotta admit I'm a bit excited for the prospects of blizzard conditions around here starting around noon.

It looks like the Quad Cities and the heart of our area will get into heavy snow starting late morning and continuing into early evening. It appears the potential is there for 4-7" of snow. I also see an exceptional pressure gradient that should generate winds of 50-55 mph. Any gravity waves could increase gusts to 60. That combined with the snow should create much blowing and drifting along with falling temperatures. It is conceivable that blizzard conditions could develop during the afternoon.

CCB porn at it's best. RAP stalls the secondary deform over this area tomorrow. Still ripping heavy snow with 60mph wind gusts at 00z. If that comes to fruition it would rival some of the better blizzards we've had around here, including the GHD. Not so much in snow totals, but extreme winds combined with at least several inches of snowfall.

That H85 map is nuts, with the 50 kt winds getting all the way to the Gulf. Also, I see an 80 kt isotach in NW IL.

I'm at the point where nothing would shock me snow totals wise at my house. Anywhere from 1-6" looks possible but now models are backing off the "2nd" defo band getting going and most of the hi res models have the trowal swinging through tomorrow evening, maybe even stalling west of 39 for awhile.

But if I had to pick I'd say 3.1" here.
