Multiple rounds of Pacific moisture have been moving through the western U.S. and will lead to cooler-than-average and wetter-than-average weather conditions to start this week. Winter weather advisories are in effect for the Cascades through Thursday for up to a foot of snow.
Accumulation through the end of the week will feature several fresh inches of snow across Idaho, Montana, Washington, Oregon, Wyoming, Utah, and Colorado. The higher terrain will see the highest amounts where up to a foot is possible.
A trough of low pressure will be followed by cold front, both pushing into the Northwest today (Wednesday). Each system will bring a wave of moisture ashore with rain at the coast and snow in the higher elevations.
Snow will diminish in the Northwest Thursday morning as the front moves eastward. Snow will increase Thursday in the Tetons and Wasatch.
