SYNOPSIS: An upper level low pressure system lifted from the Great Basin across Wyoming over the weekend of April 8-9. This system produced heavy snow over western Wyoming Friday and Saturday. The brunt of rain and snow showers shifted into central Wyoming Sunday morning. Persistent snowbands produced near blizzard conditions and 6-8" of snow between Riverton and Pavillion, and 9 inches at Edgerton. Strong wind gusts over 50 mph and moderate snow resulted in the closure of Interstate 90 Sunday evening.

Click Image To Enlarge The new GOES 16 satellite experimental high-resolution visible imagery shows high clouds clearing to reveal a lingering snowband originating off of Washakie Needles (elevation 12,523') in the Washakie Range (between Grass Creek and Dubois on the 2nd "step" of Hot Springs/Park County line) early Sunday evening. If you look close and squint, you can see a white patch that remains stationary beneath the clouds that are moving between Pavillion and Riverton . This is the remnants of 6-8" of heavy wet snow produced by similar persistent heavy snowbands this morning. The GOES-16 data posted on this page are preliminary, non-operational data and are undergoing testing. Users bear all responsibility for inspecting the data prior to use and for the manner in which the data are utilized. |
