Area Forecast Discussion National Weather Service Seattle WA 830 PM PDT Sat Sep 26 2020

SYNOPSIS. A weak weather system will exit the region tonight with isolated showers ending. High pressure aloft will be in control next week for dry and warmer weather.

SHORT TERM /TONIGHT THROUGH TUESDAY/. A few showers are lingering over the mountains and in a PSCZ this evening. This activity should gradually fade away tonight as an upper ridge starts to build in from the west. There is plenty of lingering low level moisture which should keep things mostly cloudy into Sunday morning.

The upper ridge will move over the area on Sunday and remain in place through Tuesday for dry weather. Low level offshore flow will develop on Monday and continue on Tuesday. This should limit any nighttime low clouds and fog. Highs in the 60s on Sunday will warm into the 70s Monday and Tuesday. Schneider

LONG TERM /WEDNESDAY THROUGH SATURDAY/. Previous discussion . Dry and warmer weather through Saturday with the ridge over Western Washington. Wednesday will likely be the warmest day for interior locations with highs in the upper 70s to low 80s. Flow turns light Thursday into Friday as the ridge shifts slightly east. Dry and warm through Friday with highs in the 70s. Onshore flow may increase a bit into Saturday for slighter cooler temperatures. Highs on Saturday into the upper 60s to low 70s. JD

AVIATION. An upper ridge will build into the area from the west tonight and Sunday with northwest flow aloft. At the surface, light onshore flow tonight will turn northerly on Sunday as high pressure along the coast shifts over Vancouver Island and a thermal trough to the south starts to build north. The air mass will be stable.

Areas of low and mid clouds will fill tonight then clouds will scatter Sunday afternoon. A Puget Sound Convergence Zone will dissipate later tonight.

KSEA . Mid clouds this evening. Low clouds should redevelop early Sunday morning then scatter around midday Sunday. South wind 4-8 knots will become light Sunday morning then north/northwest 4-8 knots Sunday afternoon. Schneider

MARINE. Weak onshore flow tonight. It does not look like west wind in the Strait will reach SCA strength this evening so the advisory has been dropped. West swell over the Coastal Waters are flirting with 10 feet this evening but are expected to remain just below SCA criteria then subside on Sunday. Low level flow will turn northerly on Sunday as high pressure along the coast shifts over Vancouver Island. A thermal trough will build north into the Coastal Waters for offshore flow Monday and Tuesday. Weaker offshore flow will continue Wednesday and Thursday. Schneider

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 . None.

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.
