Area Forecast Discussion National Weather Service Seattle WA 150 AM PST Thu Feb 27 2020

SYNOPSIS. A weak system passing mainly north of the region could bring a few showers to the north interior this morning. A weak ridge of high pressure will keep the region generally dry this afternoon through midday Friday. A stronger front will bring lowland rain, mountain snow, and breezy conditions Friday night and Saturday. Weak ridging is expected to produce drier conditions on Sunday before an unsettled pattern returns Monday into Tuesday.

SHORT TERM /TODAY THROUGH SATURDAY/. A few showers are beginning to appear on radar (and observations) across far northern portions of the area near Canadian border early this morning as a weak system moves into BC. Only light amounts are expected through the morning hours. Otherwise, dry conditions expected into midday Friday as weak ridging builds into the area. There should be a decent amount of sunshine for areas east of the Sound this afternoon with temperatures rising into the mid 50s. Patchy fog possible this morning and again Friday morning with overnight clearing.

Rain should reach the coast by late Friday afternoon into evening and spread inland overnight into Saturday morning as frontal system approaches. Showers will continue throughout the day Saturday behind the cold front as an upper level trough swings through. Depending on how much instability is present, could see a few thunderstorms near the coast. Main impact from this system will likely be in the Cascades as snow levels drop to around 1500-2000 feet Saturday with decent post-frontal accumulations. Will also need to monitor the near-term potential for convergence zone development behind the front as westerly push down the Strait occurs. Current forecast suggests 6-12 inches for pass levels which will cause some headaches for weekend travelers. Those with travel plans over the Cascades passes should keep an eye on the forecast and check WSDOT road conditions before they depart. In addition, breezy southerly winds will accompany the front with gusts on the order of 20-35 mph through Saturday morning.

CEO

LONG TERM /SUNDAY THROUGH WEDNESDAY/. A few showers may linger into early Sunday morning but models in decent agreement with brief ridging building across the area during the day Sunday. Ensemble guidance suggests a brief break in the action as well. Next system arrives sometime Monday into Tuesday with another shot of lowland rain and potentially impactful mountain snow. Ensembles also highlighting this period (especially Mon night into Tuesday) as potentially windy so will be something to keep an eye on. Confidence in those details is pretty low this far out. May see another brief break on Wednesday before active pattern resumes for the end of the week.

CEO

AVIATION. A weak system moving into British Columbia is brushing Western Washington with clouds and a few areas of light rain--mainly in the north early this morning. The clouds should lift and break up into the afternoon and evening hours as a weak upper ridge shifts over the area through tonight. Westerly flow aloft. The air is moist and stable but will dry this afternoon and evening.

KSEA . So far early this morning there have mainly been mid level clouds around Seattle however the layer around 035 just north of the city should expand south by daybreak. Then, after a cloudy morning, skies should clear into the afternoon and evening hours. Winds should be light and variable today.

MARINE. Seas have come up so there are small craft advisories along the coast for that. High pressure over the area will give way to increasing onshore flow with a cold front Friday evening. Onshore flow will ease on Saturday and then high pressure should build into the area for Sunday. Monday and Tuesday of next week should see strong onshore flow at times as weather systems move through the area.

HYDROLOGY. Several systems will move through the area this weekend into early next week. They will be progressive so no river flooding is expected at this time.

SEW WATCHES/WARNINGS/ADVISORIES. WA . None. PZ .

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.
