Area Discussion for - Seattle, WA

      (on/off)   Help   NOTE: mouseover dotted underlined text for definition

Fxus66 ksew 171022 afdsew area forecast discussion national weather service seattle wa 322 am pdt Mon jun 17 2019 Synopsis Areas of marine layer clouds will spread inland again this morning. Tuesday will see more moisture and perhaps a little morning drizzle or a few showers. An upper trough will move through the region Wednesday and Thursday. Weak high pressure might build toward the end of the week before an upper low arrives Sunday. Short term today through Wednesday The marine layer morning clouds have been burning off from the interior of western washington these past few days--and that's a good bet again today. However, Tuesday will see a deeper marine layer (and the tail end of a weather system that will be moving into british columbia) and some morning drizzle or shower activity will develop. Wednesday will see temps continue to cool as an upper trough begins to sag over the area and a few light showers or morning drizzle is again possible. It is worth noting that a 300mb 130-150kt jetstream will sag south over the area from Tuesday night through Wednesday night and that 700mb winds peak at 40-50kt early Wednesday morning (not that many people climb above 700mb... But they do on mount rainier) ... And of course there will be plenty of low level onshore flow as well. Long term Thursday through Sunday The chance of showers will continue through Thursday--and the sharpest shortwave upper trough arrives on Thursday, so that day could see heavier scattered showers develop. The GFS now shows a little brief ridging toward the end of the week, and then an upper low arrives on Sunday. So, we might see a little more sunshine Friday and Saturday and then go back into clouds and showers on Sunday. The ECMWF is similar, but with 500mb heights only rising to about 573dm, perhaps the most we can expect is for marine layer clouds to break up a little faster in the afternoons--and just for a day or two. It is interesting to note that 500mb heights are 100m higher today then they are forecast to be under that weak ridging late in the week, so today might very well be the last warmish day for awhile. Aviation Weak upper level ridge moving through the area today with another weak shortwave moving by to the north tonight. Westerly flow aloft. In the lower levels onshore flow will continue into Tuesday. Stratus already down the strait into whidbey island in the north and moving into the southern puget sound area to the south. By 14z most

of the lowlands will be covered by stratus with ceilings below 1000 feet and isolated visibility 1-3sm in fog. Ceilings lifting to 1000- 2000 feet late morning with the stratus retreating back to the coast in the early to mid afternoon hours. Increasing onshore flow overnight will drive the stratus back over the interior by 12z Tuesday with ceilings 1000-2000 feet. Ksea... Ceilings lowering down to below 1000 feet 12z-14z. Ceilings lifting to 1000-1500 feet 17z-19z with the clouds scattering out around 21z. Stratus returning to the terminal after midnight. Southwest wind 4 to 8 knots trying to go northwesterly this afternoon but ending up in the 270-300 degree range. Felton Marine High pressure over the coastal waters with lower pressure inland will result in varying degrees of onshore flow through the week. Gale force westerlies in the central and eastern strait of juan de fuca late afternoon and evening hours today and again on Tuesday with small craft westerlies in the morning and most of the afternoon hours. Small craft advisory winds in the adjacent waters, admiralty inlet and northern inland waters in the evening hours the next couple of days as well. Onshore flow continuing through the week with small craft advisory winds in the central and eastern strait each evening Wednesday through Friday. Felton 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 pm pdt this afternoon for central u.S. Waters strait of juan de fuca-east entrance u.S. Waters strait of juan de fuca. Gale warning from 5 pm this afternoon to 5 am pdt Tuesday for central u.S. Waters strait of juan de fuca-east entrance u.S. Waters strait of juan de fuca. Small craft advisory from 6 pm this evening to 5 am pdt Tuesday for admiralty inlet-northern inland waters including the san juan islands.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
