River Flooding to Continue in Seattle Area due to Rainfall; Light Showers in the North

Bryan Dijkhuizen

With the departure of an upper trough from the region tonight, precipitation will come to an end over the region. The flooding of the rivers will continue today.

While an upper-level ridge will develop late tonight, it will weaken throughout the weekend, enabling a weak system to brush across most of the country's northernmost region.

Another frontal system is expected to arrive somewhere around Monday.

In the early hours of today morning, a strong upper low over southwest Washington will migrate south and east of the area by this evening allowing for the first time in a long time for the region to see a significant spell of dry weather as weak upper ridging starts to form.

A frontal system is headed towards British Columbia. The ridge will be temporarily dented on Friday night and into Saturday, but apart from a few showers over the Olympic Peninsula, we should stay mainly dry, albeit a little gloomy.

Even though a warm front will pass across the state later on Sunday, the southern portion of Western Washington seems to be dry at this moment. If Seattle has three consecutive dry days, it will be the first time in more than three months that this has happened.

The continuation of the preceding conversation is followed by updates on the maritime and aviation issues.

Expect some resurgence of fog tonight and into Friday night/early Saturday due to the formation of the ridge and mild surface pressure gradient, along with the presence of residual low-level moisture.

Temperatures will normally peak in the mid-40s to near 50 degrees over the short term, however, it will be a touch warmer today.

While a weak disturbance to the north moves close enough to an area with a weakness in the ridge to produce a couple of light showers across the far north, most of which will be concentrated over the far northern Olympic Peninsula, San Juan Islands, and across Whatcom County near the border, otherwise dry conditions are expected to prevail for the majority.
