Does anyone have the saved hourly METAR data from the cold snap at the beginning of March? I'm interested in what was the coldest wind chill recorded during that time....but obviously I can't just take the lowest temp and the strongest gust of the day since they probably didn't happen at the same time.

I remember reading that the wind chill was almost -100F at one point, but I can't seem to find the hourly data for more than the past 5 days anywhere online.
