SYNOPSIS
Ridging will nudge into Western Washington through Thursday for drier weather and slightly warmer temperatures.
Troughing Friday through early next week will bring unsettled weather, including potential thunderstorms over the weekend.
Lingering troughing possible into the middle of next week.

SHORT TERM /TONIGHT THROUGH SATURDAY/
Dry conditions this afternoon with scattered cumulus across portions of Western Washington. Ridging will continue to nudge into Western Washington through Thursday for drier conditions and slightly warmer temperatures. Patchy fog possible tonight into Thursday morning for the local river valleys and into Southwest Interior.
Otherwise, highs will be in the mid 60s to low 70s through Thursday.

Troughing will develop offshore Thursday night and move towards the area on Friday as an associated front moves across the area.
This will begin a period of more unsettled weather and cooler temperatures. Showers will initially increase along the coast early Friday morning, with increasing precipitation for the interior Friday afternoon. Temperatures Friday will be a few degrees cooler with highs in the upper 50s to mid 60s.

Troughing will move overhead Saturday through the weekend, ushering in cooler temperatures aloft. Surface instability will increase post-front on Saturday with potential thunderstorms across Western Washington. Current probabilities are highest across central Puget Sound (generally 25-35% chance) due to likely convergence zone activity. Any thunderstorm may be accompanied by frequent lightning, small hail, and brief gusty winds. Shower activity will continue into Saturday night, though the threat of thunderstorms becomes limited following sunset. Saturday will likely be the coolest day of the stretch with highs in the mid 50s to low 60s.

LONG TERM /SUNDAY THROUGH WEDNESDAY/
Troughing will be reinforced Sunday across the Pacific Northwest for continued unsettled weather, including scattered showers, and a slight chance of thunderstorms. Troughing slowly slides east Monday into Tuesday, but given the proximity of the trough, slight precipitation chances remain, primarily in the mountains with more northerly flow. Uncertainty remains as to the degree of troughing into the middle of next week, but some slight warming may occur Tuesday into Wednesday. JD

AVIATION
Westerly flow in the midlevels today, becoming more southwesterly late Thursday morning as an upper low digs southward across the Gulf of Alaska. Satellite shows clouds continuing to scatter across the region this afternoon. Conditions at the area terminals are VFR and expect most sites to remain so through this evening and into the overnight period. Some patchy fog development will be possible overnight, mainly along the coast and across portions of the Chehalis River Valley. Latest NBM probabilistic guidance has roughly a 35 percent chance of KHQM seeing a few hours of MVFR conditions on Thursday morning. Probabilities across the south Sound terminals are lower, with only a 15 percent chance of conditions becoming MVFR at KOLM. Thus, any terminals in fog could see some brief MVFR, or even IFR, conditions for few hours in the morning. Expect fog to dissipate for a return to VFR by late Thursday morning. Flow in the low levels will remain northerly through the TAF period. Winds at the surface generally persisting out of the N/NE between 7-12 kt. Winds will become light this evening and will continue out the N into Thursday, increasing to 5-10 kt during the afternoon hours.

KSEA...VFR conditions will persist into Thursday. Winds generally persisting out of the N/NW this afternoon at 7-12 kt. Winds will become light overnight, shifting to the NE. Winds will increase to 5-10 kt again by Thursday afternoon. 14

MARINE
High pressure building over the offshore waters has allowed for conditions to gradually calm across the majority of the area waters today. Seas have started to subside across the coastal waters, currently persisting at 7-9 ft, and winds have eased below small craft criteria along the Strait of Juan de Fuca.

Northerly winds will increase a bit tonight along the coastal waters south of Point Grenville as the surface ridge continues to nose into the region and interact with a surface trough over northern CA/southern OR. A Small Craft Advisory remains in effect for the southernmost inner coastal zone this afternoon into tonight. Another push of westerly winds will occur along the Strait tonight. While occasional gusts to 25 kt will be possible at times in the central and eastern Strait, the majority of the guidance suggests that winds will generally remain between 10-20 kt into Thursday.

High pressure offshore will weaken on Thursday as the next frontal system approaches the region. Onshore flow will continue, with another, stronger push of westerlies expected along the central and eastern Strait Thursday night into Friday. The next front will then move across the region Friday into Saturday, allowing for winds to transition back to the south. Additional pushes of westerlies look likely down the Strait Friday and over the weekend. The pattern looks a bit more uncertain heading into early next week, though could see high pressure briefly build back into the coastal waters with additional systems weakening as they approach the region.

Seas will continue to subside into Thursday, persisting at 6-8 ft.
Seas will then subside towards 4-6 ft over the weekend and generally look to persist in this range headed into early next week. 14
