Northwest Fog to Dissipate

The stagnant fog that has been pestering the Northwest will soon be no more.

High pressure over Idaho and Utah this past weekend and during the Monday holiday was settled in, and kept the weather pattern from changing much in the West.

This high will be moving out of the area on Tuesday, making way for a new storm to move onshore from the Pacific Ocean.

On Tuesday evening, the storm will creep to the Northwest coast along with rain and snow on Wednesday.

Rain will mainly stay west of the Cascade Mountains, in the cities of Seattle, Wash., Portland, Ore., and as far south as San Francisco, Calif., by Wednesday afternoon.

Snow will fall in the mountains, with a mix of rain and snow in the lower elevations inland.

This system will continue moving eastward through the week, creating what looks to be a dry end to the workweek in its wake.

But this storm could create late-week snow potential from Indiana to New England after it crosses the Plains.

As of Tuesday morning, Seattle had been fogged in for almost five days straight. For much of this time, visibilities were at or below 1/4 of a mile.
