Synopsis
An upper level low will gradually track inland and through the area tonight and tomorrow. Showers will gradually taper Monday. Another upper level low will build offshore mid week, keeping Western Washington in an unsettled weather pattern.

.Short Term - Tonight through Wednesday
The upper level trough that has been sitting offshore and producing showers and thunderstorms in Western Washington will gradually make its way inland tonight and through Monday. Light rain showers will remain in the area through Monday afternoon. The threat of thunderstorms will remain confined to the Cascades, and will continue to decrease. We are currently expecting storms to remain on the east side of the crest, but there is the chance that one drifts over to the Western side on Monday. Conditions will quiet down throughout the area Monday afternoon/evening.

However, another upper level trough will build offshore Tuesday, which will give us a repeat in conditions. Persistent onshore flow will give way to scattered showers throughout the area. Moreover, there will once again be the potential for thunderstorms on Wednesday. Similarly to what we just experienced, the primary area of concern for storms is in the Cascades.

Long Term - Thursday Through Sunday
Unsettled is the overall trend in the long term. Ensembles are showing that the upper level trough offshore will weaken. While this will quiet things down from persistent showers and convection, it will keep us with onshore flow through the end of the week. While this will continue the trend of showers and clouds, they are expected to be less persistent and more scattered.

Marine
Weak high pressure over the northeastern Pacific will maintain fairly light onshore gradients across the water, though a weak disturbance just offshore will maintain to winds to 25 kt through the central and eastern Strait of Juan de Fuca and portions of the interior waters again this evening before winds start to gradually ease late tonight/early Monday. Current headlines remain in effect with no change. From later Monday onward, expect fairly light winds through much of the week. Seas will hold generally 2 to 4 feet over the coastal waters. 18

The daily hydrology discussion has ended until the start of the next rainy season; it will only be updated as needed until then.
