The snow is being caused by a slow-moving southward dip in the jet stream in the West and its associated low pressure system in the lower atmosphere. Strong winds associated with that area of low pressure in combination with the snow has resulted in poor travel conditions in many areas. Portions of Interstate 80 were closed Wednesday morning due to snow and wind in Wyoming.
