An active weather system will bring a series of storms into northwestern US during this week. There will be several spells of rain and snow for the Pacific Northwest during this week. A feature of this weather pattern will be small areas of high pressure which will provide brief spells of sunshine in between the storms.
Enough mild air will be present in the atmosphere during each of the storms so that snow accumulations will be minimal. However, significant snowfall will occur across the higher elevations of the Cascades during the next weekend.
During this week, the heaviest rainfall will occur in areas like western Washington and Oregon. Parts of northern California will only get light rain. During this week, the Cascades will be receiving decent amount of snow.
Although, each storm is not expected to bring significant rain from Seattle to Portland, Oregon, the rain will be enough to cause minor flooding risks. This may lead to travel disruptions.
This added rainfall will continue to add to the current record of the wettest winters ever for Seattle and Portland.
During the Midweek into the weekend the storm track will move southwards, thereby causing more rain for much of California. This pattern will enable more rain across California during the second week of March. These storms will produce significant rainfall from San Francisco to Los Angeles and heavy snowfall over Sierra Nevada.
