Area Forecast Discussion National Weather Service Seattle WA Issued by National Weather Service Portland OR 809 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 /TONIGHT THROUGH SUNDAY/. Evening water vapor imagery shows a large upper level trough covering the Pacific Northwest, Northern Rockies and northward well into Canada. There are a couple 500 mb low pres centers within this large-scale trough. Water vapor also reveals an obvious upper level jet extending along the British Columbia coast into Western Washington. This is readily apparent by the darkening in the water vapor imagery, suggesting very dry air in the mid and upper levels. KATX doppler radar at 03Z showed showed activity primarily confined to Puget Sound to the North Washington Cascades. A quick look at pass web cams showed wet roadways over Stevens and White Passes. However, cannot rule out brief periods of snow-covered roadways in heavier showers.

The 00Z NAM and 12Z HREF model guidance agree that shower activity will gradually diminish overnight. The vorticity maximum responsible for the afternoon and evening shower activity is expected to slide east to southeast into Western Idaho overnight. Thus, dynamic support for continued shower activity will diminish. The only grid adjustments for tonight was to increase sky cover, mainly over the Cascades and foothills. Models show another short-wave disturbance dropping south out of southeast British Columbia and southern Alberta Fri. The bulk of the energy appears to be focused over north-central and northeast Washington. However, the NAM and HREF forecast reflectivities indicate increasing shower activity Fri morning through the afternoon, especially over the North Washington Cascades and foothills. Snow levels are forecast to be around 1000 feet Fri morning, locally as low as 500 ft. Snow levels gradually rise to 1500 to 2000 feet in the afternoon. 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. Weishaar

LONG TERM /MONDAY THROUGH THURSDAY/. 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. Showers are generally decreasing this evening across western WA, though weak convergence maintains a more persistent area of showers between KPAE-KAWO. Conditions are generally VFR this evening, with cigs mostly 4000 ft or higher. Persistent S-SW flow will likely maintain mostly VFR conditions overnight, though occasional MVFR cigs are possible toward daybreak Fri as shower activity increases for the morning hours. Weagle

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.
