Synopsis
Low pressure spinning offshore will maintain scattered showers and isolated thunderstorm activity through the remainder of the day. The low will gradually sink southward towards northern California on Friday, allowing for showers to gradually taper across the area. Warmer and drier conditions are expected over the weekend and into next week as upper level ridging builds into the region. A return to cooler and wetter conditions looks to resume near midweek.

Short Term - Tonight Through Sunday
Latest radar shows the heaviest scattered shower activity and some isolated thunderstorm activity moving along the coast this afternoon. Expect shower activity to continue area-wide through the remainder of the day today as a vertically stacked low pressure system continues to spin offshore and eject shortwave perturbations across the region. The main hazards with any thunderstorms that do develop are small hail/graupel, gusty winds, brief heavy downpours, and cloud-to- ground lightning. Expect overall rainfall amounts for the interior (outside of any heavier shower and thunderstorm activity) to remain rather light, with most places receiving a tenth to a quarter of an inch of rain through Friday morning. Areas along the coast and Olympics will be wetter - and look to receive a few tenths to 1.25 inches of rain. With snow levels generally hovering between 3000-3500 feet today, can expect another inch of snow for the Cascade passes through this evening.

Scattered shower and isolated thunderstorm activity will wane Friday as a stronger shortwave trough moves into the eastern Pacific, prompts cyclogenesis of a new low, and pulls the current one offshore further southward towards northern California. Expect shower activity to mainly become confined to the coast and mountains by Friday afternoon and evening. Friday will be the start of a warm up across the region, with temperatures increasing a few degrees and topping out in the mid to upper 50s.

An upper level ridge will then build into the Pacific Northwest over the weekend while the aforementioned low continues to move southward towards southern California and become cut off. This upper ridging will bring warmer and drier conditions to the region, with highs expected to increase a few degrees daily- and looking to top out in the upper 50s to low 60s by Sunday.

Long Term - Monday Through Thursday
Warm and dry weather will continue into Monday as upper level ridging remains situated across the Pacific Northwest and a cutoff low resides across southern California. Temperatures on Monday look to climb into the mid 60s for areas across the interior. The ridge then looks to dampen somewhat heading into Tuesday and Wednesday as upper level troughing redevelops over the northeastern Pacific and moves into British Columbia. At the surface, a cold front looks likely to move across the region around midweek, bringing the return of wetter and closer-to-normal temperatures. 14

Marine
A surface low remains offshore with breezy winds felt throughout area waters. Gales over the coastal waters and East Strait are gradually decreasing allowing the headline to expire this evening. However, small craft advisories will remain in place for the East Entrance of the strait, Admiralty Inlet, and the Northern Inland Waters, and coastal waters. These headlines will persist into Friday, before the surface low drifts away from the area, which will let winds relax this weekend. With high pressure building overhead around this time, relatively benign conditions are expected into next week.

Combined seas around 12 to 15 feet this evening. Seas look to drop below 10 feet Friday morning, and continue to lower to around 3 to 6 ft this weekend.
