A bit off topic, but we were off the lower end of the chart in Ohio during the blizzard of 78. Wind chill was -60+. Mainly due to the winds (70+ mph gusts with sustained over 50). The temps were down below zero too, after being in the upper 40's the evening before. The 24 hour temperature drop was one of the largest ever recorded for Ohio. Over 50 lost their lives - mainly due to the white out conditions and freezing to death. Nrn Ohio and Michigan got the worst of it where the flat terrain offered little resistance to the wind.
Was 16 at the time and will never forget the sound of the howling winds, which started very early on the morning the storm hit. The howled all day and into the morning of the second day. Farmers lost an untold number of livestock, despite efforts by the National Guard who delivered feed by helicopter. Many roads around our town north of Dayton were closed for more than a week until they brought out the snowblowers from Dayton Airport and Wright Patterson AFB. Was an amazing experience.
