  1. 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.

  2. 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.
