Area Forecast Discussion National Weather Service Seattle WA 300 PM PDT Thu Apr 2 2020

SYNOPSIS. Lowland rain and mountain snow will continue off and on through Friday as a couple of weak systems pass through the area. Brief dry conditions for Saturday before rain returns for Sunday and possibly into Monday. Drier and warmer conditions are possible by the middle of next week.

SHORT TERM /TODAY THROUGH SATURDAY/. Radar showing activity has increased from this morning . as was expected . but showers remain pretty scattered. Still getting occasional reports of ice pellets or small hail with some of these cells . but these are only falling briefly and sizes remain pretty small . no greater than pea-sized.

This system will push eastward through the day and as such will see activity start to taper off this evening as the system exits. Another weak shortwave associated with an upper level low over B.C./Alberta will bring yet another chance for afternoon/evening showers for Friday . but again . that system will also likely need the help of terrain to kick off some limited shower activity. Models remain in agreement that a brief upper level ridge should bring dry conditions to the area for Saturday . although an upper level trough hot on its heels but moving further to the south will result in a sharp contrast in PoPs . around 50 pct for far southern reaches of WA and into OR while the SEW CWA will likely either remain dry or only see PoPs in the slight chance range . 10-20 pct. Temps during the short term period look to remain below normal with highs generally in the upper 40s before maybe cracking the 50 threshold Saturday. 18

LONG TERM /SUNDAY THROUGH WEDNESDAY/. Models agree on bringing some wrap around moisture from a plunging upper level low up into W WA Saturday night and into Sunday . although the northern extent of this appears to be pretty limited. GFS solutions continue to be wetter as it tries to form a link between this southern system and an upper level low up in Canada whereas the ECMWF remains consistent keeping moisture confined to the southernmost portions of the CWA. Current ensembles also favor this drier approach. Dry conditions are expected to return as early as Monday evening and look to persist for the remainder of the forecast period as upper level ridging over the Pacific becomes the main weather feature for the majority of WA. 18

AVIATION. A broad upper level trough is over the Pac NW with isolated to scattered showers across western WA. The flow aloft is northerly. The air mass is moist but most areas are seeing VFR conditions. Showers will remain in the area tonight as the trough lingers over the region. Patchy low clouds and MVFR cigs are possible Friday morning with onshore flow. 33

KSEA . Showers in the vicinity tonight with S/SW winds to 10 kt. VFR conditions expected with possible MVFR ceilings early Friday morning. 33

MARINE. Onshore flow will prevail across western WA tonight. Strongest wind/waves will be through the Strait of Juan de Fuca and Northern Inland Waters - a Small Craft Advisory is in effect. Winds will remain onshore through Friday then ease Friday night. Low pressure will shift toward OR/CA over the weekend with generally light N/NE flow over western WA. The flow will turn onshore again by Monday as low pressure shifts inland. 33

HYDROLOGY. An unsettled pattern will continue into the weekend, but precipitation amounts are not expected to lead to flooding concerns.

SEW WATCHES/WARNINGS/ADVISORIES. WA . None. PZ . Small Craft Advisory until 8 PM PDT Friday for Central U.S. Waters Strait Of Juan De Fuca-East Entrance U.S. Waters Strait Of Juan De Fuca.

Small Craft Advisory until 5 AM PDT Friday for Northern Inland Waters Including The San Juan Islands.

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.
