More Rain, Mountain Snow for Pacific Northwest

After several days of chilly and unsettled weather, another serving of valley rain and mountain snow is on the menu today across the Pacific Northwest.

Temperatures will be slightly milder today than recent days as high temperatures top out around seasonal averages.

Showers will gradually increase throughout the day from Seattle and Tacoma southward into Portland and Eugene as a weak disturbance over the eastern Pacific moves onshore over western Washington.

These showers across Washington and Oregon will mainly be of the hit or miss variety; however, periods of steadier rain will be likely along the coastal locations of Washington.

Along with the rain, snow will fall in the higher elevations of the Cascades. Any snow accumulations will remain in locations above 2,500 feet.

Snowfall totals will not be as high as they were with the last storm that passed through Sunday night into Monday. Snowfall totals will generally be between 1-3 inches. A few locations above 5,000 feet could have snowfall totals exceed 3 inches.

Although roadways will be wet in many locations, the storms are not anticipated to cause any travel delays along I-5, I-84 and I-90.

Showers will gradually taper off as weak high pressure begins to build into the Northwest Tuesday night into Wednesday.

The area of high pressure will signal a couple dry and seasonable days throughout the Pacific Northwest.

However, this dry period will be short-lived as a series of storm systems bring more unsettled weather beginning this weekend.

The next storm system will approach the northwest on Saturday, bringing more valley rain and mountain snow. Another system looks like it will be on its heels for Monday.
