Overview
|
An intense Arctic outbreak affected a large part of the Midwest, at the end of January. Temperatures fell into the 20s and 30s below zero in some areas, with wind chills at times worse than 50 below zero. Such intense cold is not very common in this area; the last comparable period was in early January 2014. A low temperature of 38 degrees below zero was observed at Mount Carroll, in far northwest Illinois; this is being evaluated as potentially the coldest low temperature ever observed in Illinois. |
