(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 ksew 261010 afdsew area forecast discussion national weather service seattle wa 310 am pdt Tue sep 26 2017 Synopsis A strong ridge of high pressure aloft combined with developing low-level offshore flow will give warming and drying to the area today through Thursday. Weather will become cool and unsettled Friday onward as a cold front moves across the area and an upper level trough settles into the region. Short term Satellite imagery shows abundant cloud cover along the coast and over the southern portions of the interior while breaks in the clouds are seen over the interior from about the seattle area northward. Some patches of fog have formed over the coastal zones and in the area that has cleared over the interior. The lower levels of the atmosphere will rapidly dry out later today as a sharp upper level ridge over the offshore waters shifts gradually eastward into the area and surface high pressure offshore builds into southern british columbia inducing low level offshore flow. Temperatures with increasing sunshine this afternoon will rise into the mid 60s to mid 70s, quite nice for the end of september. While offshore flow continues to slowly ramp up tonight into early Wednesday, good diurnal cooling and moisture trapped below an increasingly shallow inversion should result in some patchy fog again on Wednesday morning. Most of the fog will be seen over typically foggy river valleys and around the strait of juan de fuca. Any fog that does develop will rapidly burn off late in the morning leaving a dry, sunny, and warm day across the area with highs getting well into the 70s across the area. Some lower 80s are possible through the chehalis gap and in the interior from about shelton and olympia southward. Thursday promises to be the warmest day of the upcoming warm spell as the upper ridge shifts off to the east and offshore flow continues. Most locations in the interior will see temperatures rise into the upper 70s to mid 80s for what will likely be the last day of summer-like weather for the year. Enjoy this last gasp |
of summer! Albrecht Long term Onshore flow ahead of a frontal system will increase Thursday night. Then a weak front will move across the area on Friday giving a chance of some light rain to the area, mainly over the olympic peninsula. With the increase in moisture and the rapid decrease in insolation this time of year, maximum temperatures were cooled to a few degrees below normal starting Friday. Forecast models are generally consistent for Saturday showing an upper trough moving across the area giving showers. The ECMWF and canadian model ensemble means, as well as a number of GFS ensemble members show general upper troughing continuing over the pacific northwest Sunday through at least the middle of next week, while the 00z GFS operational solution shows northwesterly flow aloft and drier conditions overall starting on Sunday. The forecast for Sunday onward will lean in the direction of the wetter and cooler ensemble means and operational ECMWF per guidance and discussions issued by the weather prediction center in college park md. Albrecht Aviation An upper level ridge will shift inland today for dry and stable weather. The low level air mass will remain moist with areas of low clouds and fog - lifr to MVFR ceilings possible this morning. The air mass will dry out this afternoon forVFR conditions.

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. |
