Final December 25-27th Snowstorm Totals

December 27, 2003 - A vigorous upper level system ejected into the central Rockies on December 25th, bringing with it a large band of moderate to heavy snow to parts of the the Cowboy State.  The snow was heaviest across west central Wyoming Thursday night and continued into Friday and Friday night. Snow initially developed across central Wyoming Thursday evening as a warm front pushed north through the Wind River Basin.  Snow continued to develop along the west to east oriented boundary Thursday night and Friday.  On Friday, the low pressure area made its trek from Rock Springs at 8AM to South Pass City by 11AM and to the Kaycee area by 2PM.  Temperatures mainly remained above freezing for areas extending from eastern Sweetwater County northeast to Casper (Casper's high temperature reached 50˚F on Friday).  Warmer temperatures along with some dry air,  limited snowfall amounts in these areas.  Winds kicked up in Sweetwater and Johnson Counties Friday night, causing visibilities to drop as a result of blowing and drifting snow.  Winter weather conditions made travel difficult across the western half of Wyoming from December 25-27th.  

Here are the final storm total snowfall reports beginning on Christmas night through December 27th.  The National Weather Service would like to thank ALL of our spotters who aided in this report.
