The big story this week is the brutal cold air mass that has settled in the Northern Plains and Great Lakes states. Among our 800+ contest sites, the coldest MOS predictions are for Park Rapids, in north central Minnesota. Most of the MOS predictions are about -44 F -- how many people have ever experienced temperatures that cold? There is some uncertainty caused by the fact that modest wind speeds could prevent the temperature from getting quite that low -- here's the NWS discussion: "Tonight, the surface high will move into the eastern Dakotas and winds will decrease to the 5 to 10 kt range. Still looking on track for the coldest air in years with actual temps in the -30s and even -40s and even colder wind chills as there will continue to be some wind. Continuing the wind chill warning is a no-brainer." So let's forecast Wednesday's Tmin for Park Rapids and see how low it goes.
Question: Question: If the temperature falls to -40 F, what would the temperature be in Celsius?
