There has never been a warmer day in December in Missoula history than Wednesday, December 1 when the temperature soared to 67 degrees, setting a new record for Missoula.
You may not have been awake to realize it, but Missoula set a new record high temperature for this date of 57 degrees, but the interesting part is that the record was actually set in the middle of the night, in fact at midnight on Monday morning.
