Synopsis for the northern and central washington coastal and inland waters..A strong cold front continues to move onshore this morning but will stall over western washington into tonight as additional waves of low pressure ride northward along the boundary. While winds will ease through today, seas will remain above advisory levels. A weaker system looks to move over the area waters Thursday before high pressure builds over the area Friday.

Area Forecast Discussion National Weather Service Seattle WA 322 AM PST Tue Dec 5 2023
SYNOPSIS
An atmospheric river will impact the region today with periods of heavy rain and river flooding. An upper level trough will cross the region late in the week for a shift toward more showery precipitation, cooler temperatures, and lowering snow levels. A brief break in the active pattern is possible on Friday before another front arrives over the weekend. Drier conditions are possible by early next week.
SHORT TERM /TODAY THROUGH THURSDAY/
We've got a pretty extraordinary air mass over Western Washington this morning as an atmospheric river continues to have the region firmly in its crosshairs. To gain a sense of how moisture laden it is, the Monday afternoon sounding out of KUIL had precipitable water of just over 1.4 inches. No sounding data for the month of December dating back 75 years has yielded a number that high. Snow levels remain as high as 9000 to 10000 feet across portions of the area early this morning with rainfall rates of 0.25 to 0.50 inch per hour across much of the lowlands and higher in the mountains.
We'll need to continue to monitor this as some rates are nearing flash flood thresholds near the Sourdough and Bolt Creek burn scars. Numerous rivers are or will be reaching moderate to major flood levels. More on this can be found in the hydrology portion of the discussion.
A cold front will gradually drag onshore later this morning then stall around Puget Sound much of the day before eventually shifting east of the Cascades tonight. This will allow rainfall rates to gradually decrease as well as begin to lower snow levels. The axis of heavier precip will shift into Oregon by Wednesday morning. However, a frontal wave lifting northward across southern portions of the CWA could enhance precip rates for a few hours across the central Cascades Wednesday morning into mid afternoon. Snow levels will fall back to pass levels by early Thursday as an upper trough axis moves onshore. Models remain relatively consistent with the focus of much of the precip with the upper trough remaining south of the forecast area. With the showery nature of the precip and an absence of any significant onshore flow, snowfall for the mountains (including the passes)
should be modest at best.
LONG TERM /FRIDAY THROUGH MONDAY/
Low amplitude shortwave ridging sliding across the region will provide a brief break in the weather later Friday into early Saturday before another front arrives for the later half of Saturday into early Sunday.
Ensembles generally support the idea of this system being rather progressive. Looking into early part of next week, there is rather broad support in the ensembles of positive height anomalies just offshore as broad upper troughing develops downstream east of the Rockies. All of this points toward a relatively (and probably much needed) benign start to the week with near seasonal temperatures and a multi-day drying trend. 27
AVIATION
A mixed bag of conditions early this Tuesday morning as a cold front continues to move onshore. This front will stall over Western Washington today with additional waves of low pressure riding along it as a shortwave trough moves northeast over the Pacific Northwest keeping deep southwesterly flow aloft. Rain will continue for most of the terminals today with primarily MVFR CIGs.
The best chances for breaks and potential brief periods of VFR will be furthest north of the stalled front at BLI, KHQM, and KCLM.
Breezy to gusty west winds this morning will shift back to the south- southwest from 5 to 10 kt this afternoon.
KSEA...Primarily MVFR CIGs today as a cold front stalls overhead with additional waves of low pressure and strong southwesterly flow aloft pumping ample moisture over Western Washington. This will continue moderate to heavy rain at times through the day, which may lead to brief periods of IFR or even LIFR conditions. Rain gradually transitions to more showers overnight tonight, with more widespread coverage south of the terminal. Gusty south-southwesterly winds early this morning through 15Z will ease through the rest of the morning. Winds mostly out of the south-southwest then back to the southeast late this afternoon then turn light and variable out with a predominately northeasterly direction tonight.

MARINE
Southerly winds are easing off over the coastal waters and even into portions of the interior waters as well as a cold front pushes onshore. Winds will continue to turn more onshore this morning before turning back to the south-southwest as additional waves of low pressure move along the stalling cold front. All Gale Warnings have been converted to Small Craft Advisories, with the interior waters dropping off at 6 AM this morning. Combined seas remain on the high side from 10 to 14 ft this morning, then rise back to 15 to 20 ft this afternoon over the coastal waters. Seas finally look to drop below 10 ft into Thursday before another frontal system moves eastward over the area waters, bringing seas back above 10 ft along with the potential for gale-force winds.

HYDROLOGY
Heavy rain continuing over most of the area through this afternoon. Rainfall amounts in the 12 hour period ending at 3 AM for the Olympics range from 2.5 to nearly 6 inches ( Quinault 5.58 inches ), North and Central Cascades 1.5 to almost 4 inches, 1.5 to 2.5 inches in the South Cascades, 1.5 to 3 inches along the coast and and 0.75 inches to 1.5 inches in the interior lowlands. Snow levels up around 9000 feet will only lower slightly today.
Heavy rain will continue in the North and Central Cascades through this afternoon with another 2 to 4 inches of rain on top of what has already fallen. Rainfall amounts in other locations will be less with the atmospheric river shifting slightly inland later today.
Flood warnings are already out for most of the rivers flowing off the North Central Cascades including but not limited to the Skagit, Stillaguamish, Snoqualmie, Skykomish and Tolt. Warnings for the Snohomish river will be added this morning. The Skagit near Concrete will reach major flood stage later this morning/early this afternoon. There is a chance that the Snoqualmie near Carnation will reach major flood stage tonight.
Rivers flowing off the South Central Cascades are well below flood stage this morning but with the rain continuing through today warnings will most likely be issued for the Cowlitz, Nisqually, Newaukum and portions of the Chehalis river later this morning or this afternoon.
For rivers flowing off the Olympics, the Skokomish river could reach major flood stage this morning. The river can't go more than a couple inches above major flood stage before it starts filling up the valley. Flood warnings are already up for the Bogachiel river. With the atmospheric river moving inland, the Bogachiel will crest later this morning and begin receding this afternoon.
On the east side of the Olympics localized flooding will occur near the Duckabush and Dosewallips Rivers in Eastern Jefferson County through this afternoon.
Heavy rain coming to an end tonight into Wednesday morning. This will allow the upper reaches of the river to start receding while the flood crest makes its way downstream to the lower reaches of the rivers. Felton
