April 10-12, 2019 - A powerful spring blizzard brought heavy snow and strong winds to parts of northeastern Wyoming and much of western South Dakota. The precipitation changed from rain to snow on Tuesday night. Some areas experienced periods of intense snowfall rates associated with thundersnow. Snow amounts across the area varied widely, ranging from a couple of inches in the southern Black Hills to 30 inches over the northern Black Hills and over two feet of snow over parts of the western South Dakota plains. Wind gusts to 50 mph caused whiteout conditions in blowing and drifting snow. Travel was hazardous to impossible. |
