Another Round of Precipitation

The inland Pac-NW will see a small break in active weather this weekend. Another disturbance is set to bring more rain and snow impacts by early next week. As this system moves into the Northwest, it will funnel moisture off the Pacific inland, similar to the previous system. With snow levels dropping by Tuesday, heavy rain will turn to snow. The incoming moisture could reignite flooding potential in areas already recovering from the last round of precipitation. Heavy snow beginning Tuesday, could impact road travel below pass levels in the mountains.
