A broad upper level trough will maintain cool and unsettled conditions across Western Washington into Tuesday. Weak upper level ridging will produce somewhat drier conditions Wednesday into Friday before an active, wet pattern returns by next weekend.
Short Term - Today through Tuesday
Feels like the same song stuck on repeat this morning. Upper level trough remains in control of the regions weather as yet another embedded disturbance spreads more showers onshore and snow levels remain in the vicinity of 500 feet or so. Sundays forecast will be a virtual carbon copy of the previous couple days with scattered rain and snow showers, isolated thunderstorms near the coast, and temperatures running several degrees below normal. Another upper trough shifts southward down the British Columbia coast on Monday to keep showers in the forecast. Signs of change finally emerge on Tuesday as the upper trough axis shifts east of the Cascades and shower activity decreases across the area.
Long Term - Wednesday Through Saturday
Prospects for a brief respite from wet weather remain in the cards for the Wednesday through early Friday period. The ensemble means of both the GFS (Global Forecast System) and Euro support some low amplitude ridging building into the area as the region becomes sandwiched between upper troughs over the Gulf of Alaska and the Desert Southwest. The weakness of the ridge doesn't lend enough confidence to support a completely dry scenario, but interior portions of the CWA (County Warning Area) could string together a couple dry days. A broad trough over the Gulf of Alaska is likely to bring a return of moist southwest flow aloft by later Friday into Saturday as the first of a series of frontal systems arrives. Temperatures will gradually moderate through the extended forecast period...edging closer to near normal by next weekend. 27
Low pressure remains parked offshore with a series of low centers moving through the waters this weekend. Widespread showers will continue with the strongest bringing gusty winds and possible lightning. Otherwise, general winds will continue to ease today for most, other than the eastern Strait of Juan de Fuca and adjacent areas toward the San Juans and Admiralty Inlet where winds 25 to 30 kt will continue through much of the day. Seas continue to gradually subside over the coastal waters today. Another advisory has been issued for the outer coastal waters with winds again increasing into the 25-30 kt range late this evening and tonight. Light offshore flow develops early in the week, but gusty Fraser outflow could spread across the northern inland waters. Higher pressure builds midweek before the next front likely arrives late this week.
No river flooding is expected at this time over the next seven days.
