Officially 7.8 inches at TOL
Impressive total.
Was the snow heavy enough to cause tree limbs to break or cause power outages?

That wasn't a bad summer for my liking! The graphics and videos really take me back. That was the summer between 5th and 6th grade for me. ~not 6th to 7th.

Cool...yeah, I'm trying to collect confirmed/documented readings on the new scale...so if there is documentation somewhere, that works! I still plan to look more in depth at the 1935-36 winter, which was brutal across the northern plains.
Here it is: http://www.nytimes.com/1996/02/02/us/montana-journal-where-the-wind-chill-has-been-90.html

I couldn't find any official wind chill readings lower than -50 in late January 1996...but I'll keep looking. In the meantime, there is always good old January 1982:
Montana
Glasgow, 1/6/1982: wind chill -55 (temp -35, wind 7 mph)
It was mentioned in a news article. I'll see if I can find it again. Hopefully I converted to the new scale correctly. - But there was mention of -90 wind chills in areas of the state that morning. Of course that would be on the old scale.

Morning of 01/30/96 north central Montana had lows as extreme -40°, even some unofficial locations approaching -50° near the Canadian border. Estimated wind chills on the new scale were pushing close to -75 - -80° with 15-20mph winds.

Sioux Falls, South Dakota.
2/9/1899: -42° (all time record low) estimated wind chill -65°. (new scale)
-
Lowest Iowa wind chill readings I could find. Spencer and Estherville hit -45°F (new scale) on the morning of February 10, 2008. Probably some lower ones at some time during record keeping.

Wish we had wind chill info for 1/12/1918. Basically it was a weaker version of the 1978 Cleveland bomb but it brought in bitter cold air behind it. Some of the numbers must've been pretty low.
So there was no wind data taken back then? What kind of temperatures were there?
Graphic from GRB:
National Weather Service Forecast Offices have adjusted the threshold values of Wind Chill Temperatures that trigger Wind Chill Advisories and Wind Chill Warnings, to reflect the new formula.
Here's the formula:
Wind Chill (F) = 35.74 + 0.6215T - 35.75(V0.16) + 0.4275T(V0.16)
Where V = the wind speed value in mph and
T = the temperature in �F
Note: Frostbite occurs in 30 minutes or less at wind chill values of -18 or lower.
Beavis - BTW, good thread idea.

That one really frigid February several years back there was wind chills around -35°F at Waukegan.
For Madison, WI at least: -54°F was the lowest wind chill on January 20, 1985 between 4-5am.
