(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 ksew 222232 afdsew area forecast discussion national weather service seattle wa 332 pm pdt Tue oct 22 2019 Synopsis River flooding from Monday's rain event will continue to subside over the next 24 hours as conditions dry out. The next cold front will pass thru on Friday, bringing a quick round of rain showers to the area. As the weekend progresses, a ridge of high pressure will build into the region, allowing for a dry forecast through the middle of next week. Short term tonight through Friday It's been a rather eventful 24 hours across western washington. An organized frontal system, with rather strong WAA in its warm sector brought widespread rain across the area yesterday. Mountainous terrain received the highest rainfall with an average of 2-4 inches, though there were localized areas of over 5 inches, especially across the central cascades, where convergence was maximized. As such, a handful of rivers across the central and northern cascades, as well as the olympics were able to rise above flood stage. This lead to the first river flooding event of the season, where the snoqualmie river at the falls reached major flood stage. Most other rivers that rose above flood stage experienced minor flooding, with a select few making it into moderate flood stage. This afternoon, western washington is in a post-frontal environment, with the sfc cold front and remaining shower activity located to the south and east. Nevertheless, a few areas of drizzle remain as low level moisture remains trapped at the sfc. Visible satellite shows that some areas of clearing have taken place, with the exception of some passing high clouds. Aside from drizzle, the area will remain dry into the overnight hours, with a few rivers across the central cascades remaining near or above flood stage, though the majority should continue to recede. Areas of fog will develop overnight, in the typical spots across the sw, but also patchy areas of fog are likely around the sound. With high pressure at the sfc, and a ridge building aloft on Wednesday, the Sun with finally make an appearance!!! This will likely occur in the afternoon, after morning fog and low clouds dissipate, especially across the lowlands. This will also continue to reduce flooding concerns along the remaining rivers in flood. High pressure will remain in control through Thursday, keeping for dry conditions, albeit some more cloud cover as a river of moisture channels north into bc. On Friday, a shortwave trough across the pacific will tap into this moisture channel, swinging the next cold front through the area during the day. This front will become separated from the main atmospheric river channel as it approaches the area. In addition to this, the progressive nature of this system will allow it pass thru fairly quickly. Rain showers will be likely along the front on Friday, but no additional flooding impacts are expected at this time. Kovacik Long term Saturday through Tuesday A rather quiet long term forecast is currently in store for western washington. Per ensemble guidance, the longwave weather pattern will begin to transition to more of a far eastern pacific ridge and west-central |
us trough. Beginning Saturday, a weak shortwave trough will dive down from bc across eastern washington and make way towards the great basin area. A few showers could materialize as this system grazes by, mainly across the cascades. QPF would be minimal. By Sunday, eastern pacific ridge begins to build more firmly into the pacific northwest. This sets the local area up for a dry weather forecast-!with sun!-for much of next week. The tradeoff for this tranquil fall weather will be cooler temps-with highs generally low 50s most lowlands (mid-upper 40s near water and 30s- 40s in the mountains) with lows in the 30s (20s for mountains). Kovacik Aviation Northwest flow aloft as an upper level ridge builds into the region. The air mass is generally moist near the surface and stable. Convergence zone activity across king county this afternoon with MVFR around the central puget sound.VFR mid-level clouds otherwise with some high clouds over western washington. Generally vfr MVFR in spots into this evening with MVFR ifr low clouds by late tonight into Wednesday morning with weakening surface gradients. Lifr fog development is also possible, especially across the south sound. Winds generally light northerly. Jd ksea... MVFR CIGS this afternoon with ifr possible through 23z with convergence zone activity around. Otherwise, generally MVFR into tonight with ifr stratus possible early Wednesday morning. Fog development is also possible in the vicinity of ksea later tonight into the morning. Winds by this evening will be light northerly. Jd Marine Small craft advisory level winds for the central and eastern portions of the strait of juan de fuca as well as the coastal waters through this evening. Otherwise, high pressure will build in Wednesday and Thursday across the area with light offshore flow. Another system will slide through the waters on Friday afternoon through Friday night for SCA level winds across the coastal waters and elevated winds elsewhere. Hydrology Most rivers have crested and are receding. While the upper snoqualmie has crested it is still above flood. The lower snoqualmie is rising and will not crest until tonight. The snohomish is still rising as well. All rivers will have crested by tomorrow morning. After the current flooding is over, no new flooding through the rest of the week.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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. |
