On December 23, 2015, a rare and powerful storm system developed over the Central United States. As seen in the infrared satellite animation below, the storm tracked from Oklahoma, northeastward to the Great Lakes Region into the pre-dawn hours of Christmas Eve.

 

Warm, southerly winds developed well ahead of the system. On December 23rd, southerly flow aided high temperatures in reaching record territory. All three primary climate sites (Grand Rapids, Lansing and Muskegon) achieved record high temperatures by no less than three degrees above previous records. Warmth extended slightly beyond midnight on Christmas Eve, before beginning to cool. Grand Rapids set yet another record high just after midnight on December 24th, while Lansing and Muskegon barely missed their records.

 

Damaging wind gusts closely followed, shortly after midnight on Christmas Eve. Many locations reported gusts in excess of 40 miles per hour. Some of the highest gusts were around 70 miles per hour! A large number of residents and businesses lost power with some restoration estimates keeping power off until Sunday, December 27th.
