Winter Storm Buries Central Wyoming

October 31, 2003 -  An abrupt change to the upper level jet stream caused a wintry end to an otherwise very warm and dry October across Wyoming.   An upper level trough carved its way across the Rockies and brought a surge of Canadian cold air into Wyoming on Wednesday, October 29th followed by widespread snow.  Central Wyoming was buried under a large swath of one to two feet of snow by Thursday evening, October 30th.   The following storm-total snowfall amounts were reported on Thursday evening and Friday morning, October 31st .

Snow amounts across western and central Wyoming.
