SYNOPSIS
Upper level ridge over the area moving east this afternoon. Weak upper level trough moving through tonight with a weak upper level disturbance following Monday. Upper level ridge building Tuesday and remaining in place through Friday. Upper level trough reaching the area Saturday.

SHORT TERM /TODAY THROUGH TUESDAY/
Satellite imagery shows weak upper level ridge over the area. Some patchy low stratus has formed along the coast, but will likely dissipate by this afternoon. Temperatures across the area in the mid to upper 50s, up to 60 in Seattle as of 8AM this morning.

Upper level ridge moving east today. Light surface gradients this morning turning onshore this afternoon. Marine air moving into the area will drop high temperatures 10 to 15 degrees versus Saturday.

Upper level ridge well to the east tonight with low level onshore flow continuing overnight. Weak upper level trough moving across Western Washington. Not much moisture associated with this feature. It will enhance the marine layer over the area. Weak convergence over Snohomish and possibly Northern King County could produce a light shower. Lows in the upper 40s to mid 50s.

Upper level ridge building well offshore Monday. Weak shortwave embedded in the northwesterly flow aloft moving through bringing just some cloud cover. This plus the stratus associated with the marine push will make for a mostly cloudy day. Cooling trend continues with highs only in the upper 50s to mid 60s.

Upper level ridge offshore building into Western Washington Monday night into Tuesday. Surface gradients going northwesterly Monday night which will limit the amount of stratus Tuesday morning. With the warming temperatures aloft high temperatures will warm back up above normal, in the 60s and lower 70s. Lows Monday night in the 40s.

Felton/LH

LONG TERM /WEDNESDAY THROUGH SATURDAY/
Models starting to show more consistency in the extended period with the upper level ridge over the area Wednesday slowly weakening through Friday. Upper level trough dropping down from the north Saturday. Surface gradients remain onshore keeping temperatures from getting very warm. Warmest day with the upper level ridge the strongest Wednesday. Highs in the mid 60s to mid 70s. Highs slowly cooling down to the 60s by Friday. Lows in the 40s. Upper trough bringing more cloud cover and a chance of showers to the Cascades Saturday.
Highs remaining near normal, in the 60s.

AVIATION
Westerly flow aloft will back to southwesterly tonight as an upper ridge gives way to a weak upper trough and associated front that will cross the region late tonight into early Monday. Some patchy MFR stratus developed near the coast this morning but should scatter in the next few hours. However, increasing onshore low-level flow will bring a push of IFR to low MVFR stratus to the coast this evening. Meanwhile, expect ceilings to gradually lower into the MVFR range early Monday morning with gradual lifting to VFR possible later in the day.

KSEA...VFR with increasing high level moisture expected late this afternoon into the evening. Ceilings expected to fall to the low end of MVFR by 12Z-15Z Monday. Surface winds increasing northerly through the day, with speeds reaching 6-8 kt this afternoon and evening. Confidence on wind direction becomes lower after 12z, with the most likely scenario being a return to southerly winds. However, if the onshore push through the Strait of Juan de Fuca is stronger, this could create a more variable wind direction or delay this switch.

MARINE
Broad surface ridging offshore with lower pressure inland will remain the general synoptic situation through much of the week ahead leading to varying degrees of onshore flow. Meanwhile, seas remain rather choppy with the persistent winds over the coastal waters.

A pair of weak systems passing mainly to the north of the area tonight and Monday will enhance the onshore flow for gales later today in the central/east strait and small craft advisory conditions for adjacent waters as well as the coastal waters.
Onshore gradients look to temporarily weaken midweek before additional weak systems increase the onshore flow again later in the week. Seas will build a bit with each passing system to 7 to 9 feet, with periods remaining short, around 8 seconds, through the middle of the week. All in all, this looks very much like a typical late spring/early summer type of pattern.
