Area Discussion for - Seattle, WA
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 ksew 270332 afdsew area forecast discussion national weather service seattle wa 832 pm pdt Mon jun 26 2017 Synopsis A surface ridge offshore will maintain an onshore flow pattern over western washington through this weekend with morning low clouds and afternoon sunshine and temperatures near or a little above normal. An upper level ridge will move over the area Thursday and Friday for a brief warmer period. A weak front may brush the area with more clouds and possibly a few showers later this weekend. Short term A weak upper level trough moving across the region this evening is still bringing some mid and high level clouds to the south half of W wa. There was still a little bit of stratus along the central wa coast. Quite benign compared to the hammering the upper level trough has been giving SE wa from severe thunderstorms. This benign pattern will continue for W wa this week, dominated by the surface ridge presently centered about 750 nm offshore near 140w. This ridge will maintain a typical mild onshore flow pattern across W wa through this weekend, modulated by the upper level pattern. A low amplitude somewhat broad upper level trough will be over the region through Wednesday. This will allow the onshore flow to be a little stronger Tuesday and Wednesday which will produce more morning low clouds and cap high temperatures in the lower to mid 70s. The marine layer will remain moist enough to allow low stratus clouds to reform late tonight and again Tuesday night, with more complete coverage across the W wa lowlands than this morning. Burn-off should be about the same each day, 18z-19z 11 am-noon, leaving mostly sunny skies in the afternoon. The stratus will take a little longer to clear from the coast and some spots along the coastline may only get some brief afternoon clearing. An offshore upper level ridge will be slowly approaching the region through Wednesday, finally reaching about 250 nm offshore near 130w Thursday morning. The ridge will weaken the onshore flow and provide a little more warming, allowing high temperatures to reach the mid to upper 70s Thursday followed by highs in the lower 80s on Friday. Continuing but weaker onshore flow should produce less morning stratus Thursday and Friday mornings, but burn-off will likely still occur later in the morning. Kam |
Long term Previous discussion from the 348 pm afd... Medium range models models remain in good agreement through Friday, showing the upper ridge axis overhead around midday Friday. This will make it the warmest day of the week, however low level onshore flow and morning clouds will continue to limit the warming. Temperatures will rise into the low to mid 80s through parts of the interior, and remain in the mid to upper 60s along the coast and strait. Models still begin to differ on the details Saturday onward. The ECMWF and canadian models continue to be a little more aggressive with a system moving from the gulf of alaska into british columbia Saturday, while the GFS continues to be much weaker with this system. The GFS continues to keep the area dry through Sunday while the ECMWF and canadian bring a chance of showers to western washington late Saturday night into Sunday. For now the forecast leans towards the majority forecast, with a slight chance of showers Saturday night through Monday - mainly for the northern portion of the forecast area. Highs will cool back down to near normal, as the Fridays upper level ridge shifts to the east and low level onshore flow stays in place into early next week. Aviation A very typical pattern of morning clouds and afternoon sun is expected for the interior of western washington over the next few days. The coast from about hoquiam south had marine layer stratus for most of the day today, and it has already started to push back in. The air mass is stable. Southwest flow aloft will become northwest on Tuesday. Ksea... Morning clouds and afternoon Sun are on tap for Tuesday--the southerly breeze will probably turn around to the northwest for the late afternoon and evening hours. Marine High pres offshore with lower pres E of the cascades will result in onshore flow of varying strength this week. The flow is strong enough for a gale warning in the central and eastern strait or juan de fuca again this evening. Sew watches warnings advisories Wa... None. Pz... Gale warning until midnight pdt tonight for central strait of juan de fuca-east entrance strait of juan de fuca. Small craft advisories are in effect for parts of the coastal waters, west entrance to the strait of juan de fuca, and admiralty inlet. |

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. |
