An late spring storm has impacted portions of central and western Wyoming Tuesday through Wednesday night. A cold front became stationary across southern portions on Tuesday, allowing for cool, moist air at the surface across central portions. South of the front, warmer and drier conditions existed across southern portions, including Sweetwater and portions of Lincoln County. Southerly winds aloft brought warmer air across the state, allowing for destabilization to create showers and thunderstorms. Some thunderstorms became severe Tuesday afternoon, with hail of 0.25" to 1" being the main threats. As storms weakened overnight Tuesday, precipitation continued across the forecast area, with northern and central portions changing over to snow by sunrise Wednesday.  Snow and snow showers occurred Wednesday and Wednesday night across the region.
