Area Forecast Discussion National Weather Service Seattle WA 316 AM PDT Mon Jul 13 2020
SYNOPSIS. High pressure aloft over the Pacific will allow for dry conditions to continue into at least mid-week with slightly warmer temperatures. Some weak systems passing to the north of the area may allow for scattered showers at times for the second half of the week.
SHORT TERM /TODAY THROUGH WEDNESDAY/. Current satellite shows mostly clear skies over W WA this early morning with some passing scattered high clouds south of the Seattle metro area.
High pressure aloft over the Pacific will strengthen today and into Tuesday . amplifying the resulting ridge and expanding its influence over W WA for the entire short term period. This will leave partly to mostly sunny skies over the CWA and steadily increasing daytime highs . with Wednesday still forecast to be the warmest day. Interior lowland highs will start off in the lower to mid 70s today . then into the mid to upper 70s Tuesday before peaking Wednesday as highs approach 80. High temps for coastal locations will remain mostly steady in the lower to mid 60s.
LONG TERM /THURSDAY THROUGH SUNDAY/. The upper ridge flattens and makes its way eastward . exiting the area late Wed/early Thursday. Deterministic models disagree on what . if any . impact the approaching upper level trough and associated front will have on the area Thursday as the ECMWF holds the feature together better allowing for some rain to enter the area while the GFS dissolves the feature . keeping the CWA dry. Ensembles lean toward the ECWMF solution . although they are about 6 hours slower with the feature bringing the front into the area Friday evening and overnight. This feature exits Friday morning and while there may be a slight chance/chance of some lingering showers . generally dry conditions look to resume for most the area for the remainder of the long term as another Pacific ridge sets up shop just off the coast.
The aforementioned system will cool temps somewhat . with interior lowland highs for most of the long term sitting generally in the lower to mid 70s. 18
AVIATION. Northwesterly flow aloft into Tuesday with upper level ridge centered well offshore. In the lower levels onshore flow continuing through the week.
Mostly clear skies across the area this morning. Some stratus along the north coast slowly moving down the Strait of Juan de Fuca with ceilings near 2000 feet could get as far east as Port Angeles. The stratus will dissipate by 18z. Patchy fog along the south coast and over the lower Chehalis Valley and Southwest Interior will not last past 15z.
KSEA . Clear skies with northerly winds 6 to 10 knots. Felton
MARINE. Varying degrees of onshore flow this week with high pressure over the coastal waters and lower pressure inland. Small craft advisory westerlies expected each evening in the Central and East Entrance of the Strait of Juan de Fuca. Felton
HYDROLOGY. The daily hydrology discussion has ended until the start of the next rainy season; it will only be updated as needed.
SEW WATCHES/WARNINGS/ADVISORIES. WA . None. PZ . Small Craft Advisory from 8 PM this evening 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.

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.
