Area Forecast Discussion National Weather Service Seattle WA 846 AM PST Tue Jan 21 2020

SYNOPSIS. Wet weather for the rest of the week into the weekend as a series of systems moves through the area. Snow levels near passes today into Wednesday will rise steadily later Wednesday into Thursday. Periods of heavy rain will lead to rising rivers and the potential for river flooding later this week.

SHORT TERM /TODAY THROUGH THURSDAY/. A strong front will move inland this morning for more showers and thunderstorms (along the coast), heavy mountain snow and gusty winds. Most of the focus this morning is on a strong line of showers/thunderstorms along the coast. This area remains active where shear and instability are the greatest. Gusty winds to 40 mph expected in the North Interior (especially Admiralty Inlet Area) with the frontal passage today. Winds will ease this afternoon. Up in the mountains, heavy snow will fall in the Olympics and Cascades with snow levels around 3000 feet. Heaviest snow will be in the North Cascades at Mount Baker with 1-2 feet expected through tonight. Snoqualmie Pass may see a rain/snow mix tonight as winds change to westerly. 33

Previous discussion . Hi-res guidance indicates enough instability across the coastal waters and immediately inland to continue mention of thunderstorms this morning through early afternoon. Any convection that fires will be capable of heavy downpours and small hail. Activity should wane later this afternoon as trough axis passes to the west. Current forecast aligns well with Storm Prediction Center general thunder outlook.

Little noticeable break in the action during the day Wednesday into Wednesday night as warm front associated with our next system pushes north across the area. Cold front will follow on Thursday with another round of breezy winds. As warm, moist air pushes in, snow levels will rise steadily and be above pass levels by Wednesday evening. A few more inches likely for pass levels though at the onset. Otherwise, from here on out, heavy rain up to around 5000-6000 feet becomes the main concern. With this system, heaviest amounts will fall over the Olympics and Cascades with a bit of a rain shadow across the northern inland waters and portions of the Sound. Rivers flowing off the mountains will see rapid rises and may begin to see minor flooding as early as Thursday night into Friday morning. See hydrology section below for details.

CEO

LONG TERM /FRIDAY THROUGH MONDAY/. Previous discussion . Additional systems arrive Friday into the weekend. Past Friday, uncertainty rises in the details, especially with precipitation amounts and breaks in between systems. Entire period likely won't be a washout but flooding concerns will continue as additional rainfall will enhance river rises. Temperatures will remain on the mild side with afternoon highs in the lowlands topping out in the upper 40s to low 50s.

CEO

AVIATION. An organized frontal boundary will continue to slide eastward across the area through the day today. Ahead of the boundary, most ceilings are VFR as of 16z. Closer to the frontal boundary and in its wake, MVFR cigs are present, and most so in the vicinity of a long band of convection accompanying the front. As the convection moves east, expect the potential for VFR cigs to drop to MVFR. Will have to watch trends into the afternoon but will keep VFR ahead of the front. Any convective activity will also have the potential to bring down visibility for a brief period of time. South wind sustained 10-15kts with gusts 20-30kts through much of this TAF cycle. Unsettled weather is expected to continue even beyond the current TAF period.

KSEA . VFR ceilings should prevail most of the morning, with a greater potential for MVFR behind the passage of a cold front this afternoon. Any convective shower activity today could briefly reduce visibility. South wind 10-15kts with gusts 20-25kts through the evening.

Kovacik

MARINE. Current headlines remain unchanged. The big story this morning is the strong band of convection that moved onshore the northern Washington coast earlier this morning, and additional convection that continues to moves northward from the offshore waters of Oregon. A Special Marine Warning was issued for potential waterspout development off the southern coast of Washington. This immediate threat has since dissipated but given 0-1km helicity values of over 100 m2/s2, the threat will continue for the next hour or two. Aside from waterspouts, strong winds, associated with convective activity, will continue until the band of convection moves further inland. Previous discussion follows:

A front will move through through today with gales expected for the coastal waters and possibly the Central and Eastern Strait of Juan de Fuca. Gale Warning issued for the Northern Inland Waters through this afternoon with strong southerly winds. Small Craft Advisory level winds elsewhere with the front. Swells will increase through today with swells 15-21 feet by this afternoon. Active weather through this week as multiple systems move across the waters. SCA winds and gales possible with the systems.

Kovacik/JD

HYDROLOGY. A period of warming, rising snow levels, and heavy rain in the mountains will force sharp rises on the rivers flowing off the Olympics and Cascades in western Washington. Snow levels will rise to around 5,000 to 6,000 feet with 3 to 8 inches of rain in the mountains Wednesday through early Friday. Minor flooding is possible on several rivers as a result. Rivers may be flowing high through the weekend.

SEW WATCHES/WARNINGS/ADVISORIES. WA . Winter Weather Advisory until 4 AM PST Wednesday for Cascades of Pierce and Lewis Counties-Cascades of Snohomish and King Counties-Olympics.

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.
