Snow on the way
Major change in the weather expected
April 18, 2005
UPDATE, Monday 5 PM: The National Weather Service has issued a Winter Storm Watch for the Salt River and Wyoming Ranges, and the Upper Green River Basin including the areas around Farson, Big Piney, Pinedale and Bondurant. The Watch is in effect from Tuesday afternoon to Wednesday afternoon. As much as 6-12 inches of new snow is possible by noon Wednesday in the northern areas, including Bondurant. The Wyoming and Salt River Ranges may see up to 18 inches of new snow. Lighter accumulations, 2-8 inches, are expected around Big Piney and Boulder. Gusty winds may cause drifting snow and limited visibility, creating winter driving conditions. If travel is necessary, motorists are advised to be prepared for severe winter driving conditions.
The National Weather Service in Riverton is advising that a strong spring storm system will move into western and central Wyoming Monday afternoon and night. This system is expected to bring heavy snow through early Wednesday. Anyone planning outdoor activities should be prepared for a major change in the weather soon.
Snow will begin over the northwest mountains of Yellowstone National Park and progress east into the Absaroka mountains where significant accumulations are possible. The Wind River Mountains will see moderate snowfall by Monday night. There is also the possibility of isolated thunderstorms, especially over central and eastern Wyoming.
The Wind River Mountains may see up to 8 inches in a 24-hour period. Total snow accumulations of 5-10 inches are possible over the Cody foothills above 5000 feet. Ten to 15 inches are possible over the Absaroka Mountains.
