December 15th

Local and Regional Events:

December 15, 1983:

A storm system impacted the region on the 14-15th with five inches of snow and high winds to produce blocked roads and numerous school closings on the 15th throughout most of the eastern third of South Dakota. No travel was advised from late afternoon on the 14th due to low visibility and blocked roads in Roberts and Brookings Counties. The conditions contributed some to several traffic accidents. Meanwhile, snow also spread across Minnesota on December 13th and diminished late on the 15th. Snow accumulations ranged from 1 to 2 inches in west central Minnesota to higher amounts over 10 inches to the east. Winds increased and temperatures began to fall on December 14th as an arctic cold front pushed through the state. The strongest winds occurred during the night of December 14th and into the morning of December 15th. Near-blizzard conditions developed in the southwest and west-central sections of Minnesota where the visibility was reported to be near zero with winds of 20 to 30 mph. The wind chill index dropped to 30 below to 60 below zero. Blowing and drifting snow conditions occurred to some degree throughout all of Minnesota. Snow drifts caused many roads to close. Drifting snow continued during the evening of December 15th as the winds and snowfall gradually diminished. This event, associated with an arctic cold front, was the beginning of what would become, and remains, the coldest stretch of December days on record across most of the area. For the next nine days, beginning on December 16th, Aberdeen did not warm above -6 degrees, enduring temperatures as low as -34 F and high temperatures as low as -15 F. Other stations around the region had very similar cold temperatures during the December 16th through December 24th period, with temperatures warming into single digits above zero on Christmas Day.
