Warm December

03 Jan 2022 08:10 PM
With all the excitement of the 15 December storm and recent snow producing winter storms, the IEM Daily Feature needs to catch up on some of the highlights of 2021. Today's map takes a look at IEM climate district ranks for average December temperature. A value of one indicates the warmest December on record since at least 1893. These estimates are made by the IEM and not official, but other more official data correlates well. December was very warm for much of the country with Iowa within the transition zone to much cooler levels to our north and west. While a number of locations in Iowa set all time December record daily high temperatures on 15th, this map looks at the month on average. The winter season thus far has seen some extreme temperature gradients present over the contiguous US, which has driven some very extreme winds aloft.
