The warmest recorded temps for the second half of Oct. Understanding that the locations changed for MDT. CXY goes back to 1939 and MDT 1888. Also, with a high of 85 and low of 37, the difference of 48 degrees at MUI yesterday was the highest I remember seeing. May be bad memory though.
CXY:87 in 2016
MDT: 86 in 1947
