Synopsis for the northern and central washington coastal and inland waters - Surface ridging over the coastal and inland waters will weaken today 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. Another front is expected to arrive on Tuesday.

SYNOPSIS
High pressure will maintain mild and dry conditions today. A weak cold front will brush the region Saturday bringing light rain. Two stronger frontal systems will cross the region Monday and Wednesday bringing atmospheric river moisture and heavy rainfall to much of western Washington Sunday through Tuesday.
High pressure looks to build across much of the western US for the second half of next week brining much warmer and drier conditions.
SHORT TERM /TODAY THROUGH SUNDAY/
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 mountains during this timeframe. 55% chance for 3-day totals to exceed 3 inches in 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.
High pressure will move across northern Oregon today bringing mild and dry conditions today with partly cloudy skies as high clouds filter overhead in advance of the next frontal system set to cross the region Saturday. High temperatures today will be pleasant in the upper 60s and low 70s. A few locations may reach into the mid 70s across the Southwest Interior.
Light rain makes a return Saturday as a weak shortwave trough moves across southern British Columbia, driving a weakening cold front across western Washington. Rainfall amounts will light with only a few hundredths of an inch across the lowlands, mostly along and north of I-90. Slightly higher amounts in the Olympics and Cascades with a 55% chance for a quarter of an inch.
Otherwise, mostly cloudy conditions in the morning, with a few breaks of sun possible in the afternoon as a weak mid-level ridge attempts to build across the region ahead of the next and much stronger system. Cooler as highs drop back below normal into the low to mid 60s.
Sunday, the next much stronger frontal system will begin moving towards the Pacific Northwest as a shortwave trough ejects from a strong 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, 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 will occur Sunday night into early Monday morning, making for soggy and slow Monday morning commute. 1-day 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).
LONG TERM /MONDAY THROUGH THURSDAY/
The atmospheric river pattern remains in place through Monday and Tuesday, though peak rainfall should wind down through Monday morning.
Though rainfall rates will subside through the day Monday, breezy and wet conditions will linger through the day as additional rounds of rain move across western Washington. Can't rule out a few lightning strikes Monday afternoon across the entire area as weak instability develops thanks to cold air aloft associated with the strong shortwave trough moving overhead. Currently there is a 20% chance for thunder Monday afternoon. Highs stay on the cool side in the upper 50s to around 60. 1-day 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 1-2 inches over the Cascades.
Ensemble guidance brings a brief lull in rainfall intensity late Monday into Monday night, before another round of moderate to heavy rainfall moves back into the region ahead of yet another front. PWATs are lower with this second surge as are rainfall amounts. Rainfall will gradually subside in the transition from stratiform rain to showers through Tuesday afternoon and overnight. Showers look to linger through much of the day Wednesday, 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 spread in possible rainfall amounts during the Sunday morning through Wednesday morning timeframe range from 1 to 3 inches across the lowlands to 2 to 6 inches across the mountains, though the most likely amounts range from 1 to 2 over the lowlands to 2 to 5 inches over the mountains. Probability for 3-day (5 am Sunday - 5 am Wednesday) rainfall amounts of at least 2 inches across the lowlands is around 20% and 70% for at least 4 inches across the southwest Olympics and Cascades in King, Snohomish, and Skagit Counties. Localized amounts of up to 6 inches 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 few periods of breezy to gusty southwest winds are likely both Monday and Tuesday afternoons ahead of each of the fronts. Winds gusts between 20 and 25 mph are expected, with a 20-30% chance for gusts up to 30 mph, especially Monday afternoon. Strongest wind gust signal is across Whidbey Island and northward through the San Juan Islands and into the North Interior.
Upper-level ridging will slowly build across the West Wednesday through the remainder of the week. Showers will gradually dissipate through the day Wednesday, lingering 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.
Davis
AVIATION
A weak upper ridge will slide eastward across Western Washington today with northwest flow aloft becoming west to southwesterly tonight. VFR conditions will prevail across the region today with the exception of some patchy IFR/low MVFR in stratus near the coast and Strait of Juan de Fuca this morning. High level moisture will increase later today with ceilings lowering tonight ahead of an approaching frontal system. MVFR conditions in light rain will spread inland from the coast early Saturday morning.
KSEA...VFR today. Ceilings lower tonight under increasing high and mid level clouds. MVFR in light rain expected to develop 12Z-15Z Saturday morning. Surface winds light northeasterly this morning becoming northwesterly 4 to 8 knots this afternoon. Winds will back to light southerly by 12Z Saturday.

MARINE
Surface ridging over the coastal and inland waters will weaken today 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
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. Area rivers are expected to crest between Sunday evening and Tuesday afternoon.
