I think we really have to thank the arctic high in Montana for these gradient winds. Current surface low is 998 over Evansville and will not bomb like the January 1978 Superbomb over Cleveland did. Then again maybe "thank" is not the right word for those who lose power due to the weight of the ice or snow.

A couple pictures from tonight:

Close up of the sleet pack. You can see all the little divets caused by larger chunks of sleet impacting the 2" sleet base.

The front porch of my house. There is a corner in the roof above the right-side of the photograph, and all of the sleet on that side of the house is piling up here. The pile is about 18" high, all sleet.

This is the pile below the corner on the back porch. It's a little hard to tell, but this pile is over 2' high.

Took this one last night. This is the edge of the yard along the driveway. Amazing to see the sheer cliffs created by the combination of snowpack, heavy sleet and freezing rain.

Last one. The kids across the street made up some sleetmen today.

Things seem to be slowing down now. Looks like we'll avoid the dreaded inch of ice.

Just experienced some surprisingly loud, long-lasting thundersnow here in Peoria. Very bright flash of lightning preceded it by about 5-7 seconds, and the thunder itself rumbled for about 20 seconds. Neat!

Wherever thundersnow occurs, that's where our lollipops will be :)

Pouring snow right now...

Could you imagine the gradient if this thing did bomb to a 956 low.. with a 1056 high in Montana! 100 mb gradient across the midwest!

dude it was my pleasure, and the vids really don't do the conditions justice. I'll probably head out again, but the vids will be nothing but blurry noise at this point. It's pretty much off the deep end right now.

It's a little breezy out there... feel sorry for this guy. Looking out my front window.

Just went out and did a quick array of measurements throughout the yard. Came up with an average depth of 11" out of areas that seemed to have less drifting. There are some drifts of 2-3', but also a few areas where you can the frozen crust beneath. Given that we started with just under 4" on the ground that puts us up around 7". Will do another measurement after midnight.

No doubt. Wicked enough here with gusts easily over 45MPH and sideways sleet. Pretty freaking awesome storm even if we don't get snow here.

It is like atmospheric magic. A meteorologist could not have co-located everything at once at the same time over one area. Tanking mid level heights with the incoming PV max, the most divergent portion of that upper jet coupling, strong 600-800 frontal forcing, strong low level moist theta-e advection into the frontal circulation, and extreme convergence into the low level cyclone. I am thinking this is going to be ripping heavy TSSN over N IL like nothing before.

most exciting thing I've read since following this storm starting about 10 days or so ago :thumbsup:
