Area Forecast Discussion
National Weather Service Seattle WA
805pm PDT Sunday Jun 16 2024

Synopsis
An upper level trough over Western Washington will shift east of the area on Monday. High pressure aloft will gradually build through the week for a trend toward drier and warmer conditions. Another upper trough is expected to approach the region late next weekend for a cooling trend and a returning chance of showers to portions of the area.

Short Term - Tonight Through Thursday
There are just a few showers left, with some producing cloud flashes of lightning in Pierce and Lewis counties. Activity should wane considerably after sunset. Other than that, no forecast changes have been made this evening and the previous discussion will follow, including an update to the aviation and marine sections.

The trough axis will be east of the Cascades on Monday, but continued weak troughing aloft will keep clouds and a chance of showers in the forecast. Heigheights continue to rise on Tuesday with onshore flow weakening. This will allow much of the area to clear out by Tuesday afternoon with temperatures bouncing back to near seasonal levels. Upper ridging centered well offshore continues to strengthen on Wednesday as 500 millibar heigheights approach 570 dam with 850 millibar temps approaching 14 C. With thermal troughing just to our south and only weak onshore flow, much of the interior of Western Washington should warm into the mid to upper 70s with 60s along the coast.

Long Term - Friday Through Monday
Low amplitude ridging continues to build across the area Thursday and Friday for continued dry and warmer conditions with portions of the interior from Seattle southward reaching near or above 80 degrees. Ensembles are in fairly good agreement that the ridge axis will shift east of the region early in the coming weekend as an upper trough deepens along the British Columbia coast. This will result in a cooling trend along with a returning chance for showers...especially over the Olympic Peninsula and across the North Interior. 27

Marine
High pressure over the NE Pacific will maintain onshore flow over western WA this week. Highest wind and waves will be through the Strait of Juan de Fuca, mainly during the afternoon and evening hours. The strongest pushes will be tonight and Monday afternoon, which may affect small craft. Seas remain at 4 to 6 feet throughout the week.
