Fxus66 ksew 241603 afdsew area forecast discussion national weather service seattle wa 903 am pdt Sat aug 24 2019 Update A weak shortwave trough is progressing rather quickly across the state of washington this morning and is readily apparent in water vapor imagery. This shortwave is embedded within a larger scale cyclonic flow regime that essentially extends from alaska into the northern rockies, with best strongest shortwave energy across bc. Associated with some of this stronger energy in bc is a weak sfc reflection in the haida gwaii vicinity that has carried a trailing cold front southward towards the coastal waters of the pacific northwest. Some shower activity is seen along the washington coast with this weakening frontal boundary. These showers will continue to push inland over the next few hours this morning before gradually diminishing with eastward progress. Therefore, best chance of rain into much of the afternoon with remain west of puget sound, with mostly cloudy skies expected across the area with some Sun breaks. Behind the weak front later this afternoon into the evening will be a decent onshore push of westerly winds. Some hi-res guidance is showing a weak convergence zone developing in the northern sound vicinity as westerly winds down the strait of juan de fuca push into the north sound and converge with SW low level flow in the central south sound. Therefore have added a slight chance showers in this timeframe across this area and into portions of king and snohomish counties. Any QPF resulting from shower activity will be light, assuming this zone even develops. Little change in the pattern overnight into Sunday morning, though heights will begin to quickly rise late in the day as a ridge across the pacific into california and the desert SW begins to build north. Aside from an adjustment to the pops wx forecast to account for potential convergence zone later today, the rest of the forecast is on track and was left as is. Previous discussion included below with an aviation and marine discussion update. Kovacik Prev discussion issued 311 am pdt Sat aug 24 2019 Synopsis A weak upper level trough will move by to the north today and tonight. An upper level ridge will begin building offshore on Sunday. The ridge will continue to build and shift over western washington Tuesday and Wednesday with the low level flow going light offshore. The ridge will weaken Thursday and Friday with low level onshore flow returning to the area. Short term today through Monday Satellite imagery shows cloudy skies over western washington at 3 am 10z. Most of the cloud cover is of the mid and high variety. Temperatures were in the 50s to lower 60s. Lots of cloud cover today into tonight as a weak trough moves by to the north. Could be enough lift with the trough to produce a few showers from about a bellingham to astoria line westward today and mainly over the cascades this evening. Any precipitation that does develop will be light. With the cloud cover high temperatures will continue to be a little below normal, in the mid 60s to mid 70s. Lows tonight mostly in the 50s.

Increasing low level onshore flow later tonight into Sunday with the trough east of the area. Low clouds developing along the coast spreading inland Sunday morning. Marine layer not deep enough to get the stratus all the way to the cascade crest but deep enough to keep skies mostly cloudy through the morning hours. Upper level ridge beginning to build offshore with 500 mb heights rising over western washington but too late to warm high temperatures Sunday with readings once again in the mid 60s to mid 70s. Upper level ridge continuing to build offshore Sunday night into Monday with the surface gradients going northwesterly. This will limit the cloud cover in the morning on Monday. Monday morning the coolest morning of the month with lows in the mid 40s to mid 50s. Highs on Monday warming a little, into the 70s. Long term Tuesday through Friday Upper level ridge moving over western washington Tuesday and Wednesday with 500 mb heights in the lower to mid 580 dms. Low level flow turning offshore but 00z runs are weaker with this development versus previous runs. Models still have 850 mb temperatures warming into the plus 16 to plus 20c range but with the weaker offshore flow scenario will have the warmest locations near 90 with the remainder of the area in the mid 70s to upper 80s. The weaker offshore flow scenario leads to a quicker return to low level onshore flow on Thursday as the upper level ridge begins to weaken. Upper level ridge continues to weaken on Friday with low level onshore flow. The models have a weak surface low over the oregon and washington coastal waters limiting the strength of the onshore flow. For now will go with a 2 day weak push scenario with around 5 degrees of cooling both Thursday and Friday. Felton Aviation Westerly flow aloft will become more northwesterly today as an upper level trough departs the area. Onshore flow at the surface. GenerallyVFR CIGS at this hour with MVFR along the coast and across a swath of the puget sound near ksea and kbfi. ExpectVFR cigs by late morning across the area with mid to high level clouds through the afternoon. Winds generally southerly becoming more northerly for some by later this afternoon. Winds 5-10 knots. Ksea... MVFR CIGS have developed with MVFR possibly through the next few hours. Expect improvement toVFR by late morning midday. Mid to high clouds this afternoon. Southwesterly winds becoming more northerly into this evening. Winds 5-10 knots. Jd Marine Onshore flow continues through today. A weak front will move across the area today with another westerly push down the strait this evening into tonight. Gradients look stronger with this push but still under gale criteria so have small craft advisory for the central and eastern strait of juan de fuca through tonight. Onshore flow through Monday with offshore flow Tuesday and through much of next week. Jd Hydrology The daily hydrology discussion has ended until the start of the next rainy season; it will only be updated as needed until then. Sew watches warnings advisories Wa... None. Pz... Small craft advisory from 4 pm this afternoon to 5 am pdt Sunday for central u.S. Waters strait of juan de fuca-east entrance u.S. Waters strait of juan de fuca.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
