The first month of the new decade started with bitterly cold arctic air. The arctic outbreak was noteworthy for its persistence. The number of consecutive days below freezing was tied for the third longest at Paducah and sixth longest at Evansville. A light to moderate snowfall from 2 to 4 inches accompanied the arctic air on the 7th.
Following the arctic air came an extended stretch of relatively mild weather. Evansville and Paducah spent the next twelve consecutive days with above normal daily average temperatures. The highest temperature of the month at Paducah was 60 degrees on the 19th.
Following the mild streak came another blast of very cold air and snow. The biggest snowfall since the December 22-23, 2004 winter storm brought 4 to 8 inches to most of the region. Temperatures on the last few days of the month averaged about 15 degrees below normal.
Once it was all averaged together, January was about three degrees colder than normal. The two snowfall events made up for a lack of snow in December, placing our seasonal snowfall on a pace to reach normal levels. Normal seasonal snowfall is about ten inches at Paducah and thirteen inches at Evansville.
The streaky temperature pattern can be seen in the daily average temperatures. Daily average temperatures were:
