Much colder weather and snow forecast for western Wyoming
Snow could reach valley floors
October 5, 2018
The National Weather Service advises that much colder and wet weather are on tap for this weekend into next week for western Wyoming.
A storm system will spread precipitation across western and central Wyoming beginning Saturday and continuing into Monday. Light snow will fall in the western mountains Saturday with generally a cold rain in the valleys. This precipitation will begin to spread into areas east of the Continental Divide and across the I-80 corridor Saturday evening. Lower elevations east of the Divide may see mainly rain or a rain and snow mix into Sunday. Accumulating snow is anticipated above 6000 feet.
A second round of precipitation is expected across central and southern Wyoming Sunday night into early Monday. At the same time, colder air and gusty northeast wind of 15 to 25 mph will push through these areas. Snow accumulations of one to three inches are possible by Monday morning across the lower elevations east of the Divide. This could create travel impacts during the Monday morning commute to work and school. The least likely location for accumulating snow will be in the Big Horn Basin.
Hunters, hikers, and other outdoor enthusiasts should be prepared for accumulating mountain snow and much colder temperatures. Several inches of new mountain snowfall is expected by Monday morning, especially above 6000 feet. Temperatures will be even colder Monday night with overnight lows in the teens.
High temperatures through next week are likely to be 15 to 20 degrees below normal with readings in the 40s to lower 50s. Additional precipitation is likely through Friday with Wednesday possibly presenting the best chance for more rain and snow.
