Synopsis for the northern and central washington coastal and inland waters - A frontal system moving across the coastal waters will dissipate as it moves onshore this morning. A stronger front will approach the waters Sunday night and move onshore early Monday morning. Another front is expected to arrive on Tuesday. High pressure will then build back into the coastal waters on Wednesday.

SYNOPSIS
A weak cold front will continue to move inland tonight, bringing light rain to the region through Saturday. A series of strong frontal systems will cross the region Sunday through Tuesday, bringing in heavy rainfall across western Washington associated with an unseasonably late atmospheric river pattern. Many rivers across the region remain under a Flood Watch. High pressure looks to build across much of the western US for the second half of next week, brining much warmer and drier conditions.
Key Messages for Upcoming Active Weather Pattern
* Late season atmospheric river pattern will develop Sunday through Tuesday.
* Moderate to heavy rainfall of 1-2 inches across the lowlands during this timeframe.
* Heavy rainfall amounts of 2-4 inches across the coast and mountains during this timeframe. 60% chance for 3-day totals to exceed 3 inches ending Wednesday morning.
* Snow levels above 4500 feet will will promote additional runoff with several area rivers in the Cascades forecast to enter Action or even Minor Flood Stage. A Flood Watch remains in effect across portions of western Washington.
SHORT TERM /TONIGHT THROUGH TUESDAY/
Light rain will spread inland tonight as a weak shortwave trough moves across southern British Columbia, driving a weakening cold front across western Washington. Rain will continue to move eastward over the Olympic Peninsula tonight and inland towards the Cascades through the morning with light accumulations generally a tenth of an inch or less. Otherwise, mostly cloudy conditions will persist through the morning, with a few breaks of sun possible in the afternoon as a weak mid- level ridge attempts to build across the region. High temperatures will fall below normal into the low to mid 60s, kicking off cooler conditions for the next several days as an atmospheric pattern develops.
A much stronger frontal system will cross the Pacific Northwest on Sunday as a shortwave trough ejects from a deep closed low over the Gulf of Alaska. Rain will spread inland well ahead of the warm front associated with this system by early Sunday morning, leading the way to a wet Sunday through and through. Rainfall rates gradually increase through the day Sunday, reaching 0.05-0.1 inches per hour Sunday night, though NBM deterministic forecast rainfall rates keep 0.1 inch per hour rates confined to the Cascades and Olympics through the duration of this atmospheric river event. Peak rainfall rates are on track to occur Sunday night into early Monday morning for much of the region, making for a soggy and slow Monday morning commute. Models continue to show 24-hour rainfall totals through Sunday night of 1-1.5 inches across the lowlands (60% chance for 1-day totals of at least 1 inch by 5 am Monday, with lower chances to around 30% at lower elevations near Puget Sound) and 2-3 inches across the Cascades and Olympics (45% chance for 1-day totals of at least 3 inches by 5 am Monday across the southwestern Olympics and Cascades in Snohomish County).
Though rainfall rates will ease throughout the day Monday, breezy and wet conditions will linger through the day as additional rounds of rain move across western Washington. A few lightning strikes also cannot be ruled out (20% probability) Monday afternoon across western Washington as weak instability develops due to cold air aloft associated with the strong shortwave trough moving overhead. Additional 24-hour rainfall amounts from Monday morning through Tuesday morning will range from half to three quarters of an inch over the lowlands, one to one and a half inches over the Olympics, and one to two inches over the Cascades.
Ensemble guidance brings a brief lull in rainfall to the lowlands late Monday night, but will provide little relief to the wet conditions as the atmospheric river pattern continues into Tuesday. Another round of moderate to heavy rainfall will return to the region ahead of yet another front, expected to pass across the region throughout the day on Tuesday. PWATs are lower with this second surge as are rainfall amounts. Rainfall will gradually subside in the transition from stratiform rain to showers Tuesday afternoon with lighter shower activity lingering overnight.
Showers look to linger through much of the day Wednesday post- front, with the 500 mb flow pattern favoring Puget Sound Convergence Zone formation across northern portions of the sound from Whidbey Island into northwestern Snohomish and Skagit Counties.
Total rainfall amounts between Sunday morning through Wednesday morning will likely range from 1 to 2 inches across the lowlands and 2 to 5 inches across the mountains, though some uncertainty still remains in how strong this atmospheric river will be.
Ensembles show a high (70%) chance for at least 4 inches across the southwest Olympics and Cascades in King, Snohomish, and Skagit Counties. Localized amounts of up to 6 inches also cannot be ruled out across central Snohomish County according to the NBM (40% chance), which is where the highest event total liquid precipitation totals are likely to occur. A Flood Watch has been issued for many of the area rivers for local rises that may exceed minor flood stage.
A few periods of breezy southwest winds are likely ahead of each of the aforementioned frontal systems. Winds gusts between 20 and 25 mph are expected on Monday and Tuesday, with a 20-30% chance for gusts up to 30 mph. Strongest wind gust signal is across Whidbey Island and northward through the San Juan Islands and into the North Interior.
High temperatures heading into early next week will continue to cool under the deep troughing pattern. Upper 50s to mid 60s are expected for Saturday while temps cool even further with both Sunday and Monday only seeing highs ranging in the mid 50s to around 60. The increased cloud cover from these systems will hamper the diurnal spread as overnight lows throughout the near term ranging in the upper 40s to lower 50s.
Davis/Lindeman
LONG TERM /WEDNESDAY THROUGH SATURDAY/
Upper-level ridging will slowly build across the Western US Wednesday and through the remainder of the week. Showers will gradually dissipate through the day Wednesday as drier air moves in, with potential for lingering light shower activity into early Thursday over the mountains. A warm up then looks to commence as high temperatures climb into the 70s and near 80 by Friday. The 00Z run of the GFS and several additional GEFS members now bring a frontal system across the region Friday through Sunday, though the EC and ENS members largely keep the ridge in place. This can be seen in the long range ensemble cluster analysis, with the GEFS favoring a weaker ridge and the EC favoring ridge city. Definitely something to watch in the coming days. Didn't deviate from the NBM Thursday and Friday given this uncertainty, which keeps highs above normal, though mostly in the upper 70s rather than in the 80s as EC ensemble is predicting. For now, HeatRisk values remain the yellow/minor risk category Friday.

AVIATION
A weak upper ridge will continue eastward across Western Washington tonight with northwest flow aloft becoming west to southwesterly. VFR conditions will prevail this evening before ceilings lower later tonight ahead of an approaching weak frontal system. MVFR conditions in light rain will spread inland from the coast early Saturday morning.
KSEA...VFR into tonight. Ceilings lower overnight under increasing high and mid level clouds. MVFR in light rain expected to develop 12Z-15Z Saturday morning. Surface winds northerly with occasional shifts to the northeast or northwest 4 to 8 knots this evening before shifting to light southerly by 12Z Saturday. 27/18/McMillian
MARINE
Surface ridging over the coastal and inland waters will weaken this evening ahead of a frontal system that will dissipate as it moves onshore Saturday morning. A stronger front will approach the waters Sunday night then sweep onshore early Monday morning.
This system is likely to produce headlines for the coastal waters on Sunday. Unseasonably strong post-frontal onshore flow will likely generate headlines for both coastal and much of the inland waters late Sunday night into Monday. Another front is expected to arrive on Tuesday with elevated winds and choppy seas requiring additional headlines. 27/18
HYDROLOGY
A late season atmospheric river pattern is expected to develop Sunday through Tuesday, bringing ample rainfall to western Washington. Rainfall totals of 1 to 2 inches across the lowlands and 2 to 4 inches, with a 40% chance for totals of up to 6 inches in central Snohomish County. With snow levels forecast to remain mostly above 5000 feet, runoff will be increased with river likely to run unusually high for this amount of rainfall after a relatively benign past month or two. Currently, the Snohomish, Skykomish, White, Skagit, and Skokomish Rivers are forecast to approach or enter Action Stage, with the Snoqualmie River forecast to near Minor Flood Stage at Carnation by Monday afternoon. This may impact use of the river flood planes that are normally dry this time of year. A Flood Watch remains in effect for much of western Washington. Area rivers are expected to crest between Sunday evening and Tuesday afternoon.
