(Wednesday, April 18, 10:41 AM Update) The National Weather Service out of Riverton is advising that an area of showers and thunderstorms will be moving rapidly North across the Upper Green River Basin and across the adjacent foothills and mountains through Noon on Wednesday, April 18. Some of the stronger storms will be moving into the Big Piney area before 11:00 AM.
Expect strong, gusty winds from the South with these storms with gusts of up to 50 miles per hour. Nearby thunderstorms could cause even stronger winds. Also, brief, heavy rain is possible, along with some small hail associated with these storms. Local snowfall amounts of 1-3 inches can be expected above 7500 feet elevation.
Snow showers and isolated thunderstorms and rain showers are expected to continue Wednesday and spread Eastward across the state during the late morning and afternoon hours. As the storms spread East of the Continental Divide mountains, the unstable atmosphere will allow for additional thunderstorms to spread across Natrona, eastern Sweetwater and into southern Johnson Counties. Expect strong wind gusts of up to 55 miles per hour and possible small hail during the afternoon and evening hours.
Some isolated storms may have the potential to bring damaging winds in excess of 60 miles per hour and larger hail across the East. Snowfall of around 2 to 4 inches are possible across the Big Horn and Western mountains overnight. Showers and thunderstorms are expected to continue into the overnight hours tonight.
Travelers can expect the potential for strong winds, and snow-packed, slick roads across the West today and into the afternoon hours.
