4am/April 26: The higher terrain of southeast Wyoming will begin to see snow showers accumulate later tonight. Elevations that are prone to higher snowfall accumulation in the spring will be the most vulnerable this weekend. A Winter Storm Watch is in effect for the I-80 Summit where slightly lower confidence exists for weather impacts. Higher confidence exists for the Sierra Madre and Snowy Range Mountains. A Winter Weather Advisory and Winter Storm Warning have been issued to reflect this. For more information please go to weather.gov/cys
