Fxus66 ksew 260255 afdsew area forecast discussion national weather service seattle wa 755 pm pdt Sun aug 25 2019 Synopsis A strong ridge of high pressure will begin to build into the area tonight thru mid-week. Low level onshore flow will also transition to offshore flow late Monday into Tuesday. This combination will bring unseasonably hot temperatures to western washington with temperatures peaking on Wednesday. A weak system will bring a brief rest on Thursday before another ridge builds over the area at the end of the week. Short term tonight through Wednesday Current satellite imagery and a look out the window agree that skies are generally clear over the area. There are still a couple of patches out there... But the trend is for these bits to thin out. The exception to this may be along the coast where weak onshore flow may bring a return of marine stratus. Monday will kick off a week full of unseasonably warm conditions as upper level ridging will continue to strengthen over W wa but the furnace does not really kick on until gradients turn the low level flow offshore later in the day. With flow being in transition through the day... In increase in temps will be mainly from the upper level ridge and clear skies... Thus only being a few degrees warmer than what was observed today with afternoon highs still generally in the 70s with the SW interior hitting around 80. Tuesday will see this combo of offshore flow and strong upper level ridging have a larger impact with afternoon highs in the lower to mid 80s along the coast and the mid 80s to around 90 for the interior. While this will be the peak for temps along the coast... Wednesday will bring the hottest temperatures to the interior... With locations from the seattle metro area south seeing temps in the upper 80s to around 90 and the SW interior getting into the lower 90s. This kind of heat will result in a moderate heat risk over much of w wa for both Tuesday and Wednesday... Meaning that those more sensitive to heat will be at risk unless simple measures are taken. While this heat will not meet advisory thresholds... Those finding themselves or their pets outdoors for any prolonged period of time Tuesday and Wednesday are encouraged to take regular breaks and hydrate often and if traveling or shopping... Remember to never leave children or pets unattended in a hot vehicle. Smr Long term Thursday through Sunday From previous discussion... On Thursday, the ridge will begin to dampen across the region as a shortwave trough approaches the area from the sw. Guidance is having a tough time determining the amount of moisture associated with this weak system as its projected path takes it across southern washington into eastern washington. For now will keep slight chance of showers in for the far SE portion of the cwa. Enough afternoon destabilization should yield enough CAPE for a chance for a thunderstorm, mainly along and east of the crest, which could pose fire concerns. Despite weak troughing with the shortwave, guidance still keeps temps in the low-mid 80s, so while it may not be quite as hot as Wednesday, it may still remain rather warm. Will have to watch trends over the coming days: more cloud cover and showers

could keep things cooler, whereas a weaker system or a more southerly track could keep those conditions to our south. By Friday, the ridge noticeably reestablishes itself across the area, primarily in response to a deepening closed low across the northern pacific. Yesterday, guidance wanted to bring this low towards washington rather quickly with some wetting rain, essentially ending our brief period of heat. Last few model runs now slow this system down considerably, with a more noticeable amplification of the ridge. It remains possible for temps to warm back up Friday and Saturday now. For now not going as high on temperatures as the middle of the week, but have nudged temps a few degrees. Models then diverge later in the weekend regarding closed pacific low. Unfortunately, ensembles don't really help clear anything up. Deterministic ec brings front into the area with showers while gfs keeps ridge over area. Given solutions in previous runs have shown potential for showers, re-introduced just a slight chance, tho it remains possible the closed low could get "cutoff" from faster westerly flow to the north, which if is the case, western washington gets to hang onto the ridge. Right now, leaning slightly towards the more progressive solution, which would favor the ec a tad. Kovacik Aviation Northwesterly flow aloft as an upper level trough departs the pacific northwest. Onshore flow at the surface. Vfr conditions in place over W wa this evening and are expected to remain in place for most of the area overnight and into Monday. The exception to this may be along the coast where marine stratus may cause for MVFR conditions during the overnight hours and early Monday morning before conditions clear by Monday afternoon. Ksea...VFR conditions tonight and Monday. Northerly winds at 4-8 knots. Smr Marine Onshore flow continues into Monday although gradients will not be as tight as previous days. As such... Winds in the strait are just shy of SCA criteria. Will continue to monitor... But even the usually cantankerous race rocks is adhering to the forecast... So no headlines in place for the evening forecast package. Surface flow will shift to offshore late Monday and into Tuesday and is expected to persist through much of the week. Smr Fire weather Very warm temperatures and low relative humidities are expected Tuesday and Wednesday with poor relative humidity recovery especially Tuesday night into Wednesday morning. Wednesday will be the warmest and driest day. Thursday will likely see cooler temperatures and improved relative humidities. Sew watches warnings advisories Wa... None. Pz... None.
