Area Discussion for - Seattle, WA

Fxus66 ksew 242208 afdsew area forecast discussion national weather service seattle wa 308 pm pdt Sat aug 24 2019 Synopsis Weak perturbations in the NW flow aloft will continue to traverse the area into Sunday morning, allowing for some mid and high cloud cover. A ridge will build north into the area late Sunday and continue through Wednesday, with a late summer warming trend likely with highs in the mid to upper 80s. This will make for warm and dry conditions through much of the week before troughing pattern returns late in the week early weekend with a chance for showers. Short term tonight through Tuesday The upper level pattern this afternoon features a broad swath of NW flow aloft, extending roughly from the gulf of alaska into the pacific northwest and northern rockies. This flow regime then gives way to a more split flow pattern downstream across the plains, with ridging across the midwest & great lakes and weak troughing across the south. At the sfc, a weak low in the haida gwaii vicinity has essentially dampened, with trailing cold front that attempted to push inland across washington state more of a diffuse boundary at this point. East of the rockies, a very expansive area of high pressure center ~1028mb encompasses much of the eastern us. Earlier today, a fast moving shortwave trough darted across washington and as of 21z is located in central montana. This wave had enhanced some mid and high level moisture that has also largely carried east. In addition, some light shower activity made it to the coast and into the lower chehalis valley and olympic peninsula. Appreciable lack of dynamics both at the sfc and aloft was responsible for the demise of most this activity into the afternoon. Some shower activity is currently noted across skagit and whatcom counties. There is some enhanced shortwave activity across far southern bc very near the canada us border that is likely the source of sufficient lift for this activity. Going forward to later this afternoon and evening, a better onshore push of westerly low level wind is expected in the wake of the fizzling frontal boundary. The strongest winds will slide down the strait of juan de fuca into the northern puget sound vicinity. These winds could potentially converge with more S SW in the central southern sound. Although not strong, this may allow for a convergence zone to develop with a few light showers as some low level moisture hangs in place. Slight chance pops remain in this general area into king and snohomish counties for a few hours this evening. Some cloud cover is likely Sunday morning with a reinforcing shortwave trough glancing the northern border of the area during the morning hours. Heights will drop briefly but best moisture remains up in canada. Heights will then begin to rise as a ridge across the pacific starts to build N ne. Skies are expected to clear thru the day as this happens. Much of the same for Monday with ridge influence a bit better than Sunday. Low level flow will still be onshore as large area of sfc high pressure remains offshore so could have some stratus near the coast but otherwise sunny skies. Low level flow then turns offshore on Tuesday as a thermal trough builds north from california. With upper level

ridge influence, this will make for noticeably warmer temps, into the lower to mid 80s for most. Kovacik Long term Wednesday through Saturday Upper level ridge will remain in place to begin the extended, as will low level offshore flow. Wednesday will likely be the warmest day of the week with highs at least mid to upper 80s across the interior. By Thursday, the ridge will begin to dampen, with axis shifting east, opening the region up to more of a SW flow aloft regime. A few weak shortwave disturbances appear to be embedded in the larger scale flow, which may help enhance at least some mid and high level cloud cover, even maybe a shower or two across parts of the pacific northwest. This may keep temps a few degrees cooler if this were to verify, however, mid level heights still remain fairly high, so regardless it will continue to be warm with highs in the 80s for many. By Friday, a system well offshore the washington coast will amplify. This will help reestablish the ridge to some degree across the pacific northwest, despite some weak perturbations becoming trapped underneath. By the end of the forecast period on Saturday, larger scale trough looks to return to the region, with which some showers may begin to spread into the area along a sfc cold frontal boundary. Kovacik Aviation Northwesterly flow aloft as an upper level trough departs the pacific northwest. Onshore flow at the surface.VFR cigs for most with MVFR along the northern tier of the area. ExpectVFR through the afternoon into tonight with mid and high level clouds around. MVFR late tonight (09z-12z) with marine stratus push. Winds generally southerly becoming northerly for some this evening. Winds 5-10 knots. Ksea...VFR CIGS with mid and high level clouds. MVFR CIGS with stratus tonight into Sunday morning. Winds generally southerly becoming more north-northeasterly tonight. Winds 5-10 knots. Jd Marine Onshore flow continues through the weekend. A weak front will move across the area today with another westerly push down the strait this evening into tonight. Small craft advisory winds for the central and eastern portions of the strait of juan de fuca later this afternoon through tonight. Onshore flow into 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 until 5 am pdt Sunday for central u.S. Waters strait of juan de fuca-east entrance u.S. Waters strait of juan de fuca.

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.
