SYNOPSIS
An atmospheric river will impact the region through Tuesday with periods of heavy rain and an increased risk of 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 additional systems move through the region over the weekend.
SHORT TERM /TODAY THROUGH WEDNESDAY/
The radar is largely devoid of precip as of 2 AM PST as the region experiences another lull in activity. A quick look at the water vapor satellite loop shows a lengthy moisture tap just offshore being pulled northward ahead of a broad upper trough centered near 48N/150W. Surface analysis shows a warm front gradually marching northward along the northern Oregon coast. This warm front will lift northward across the area later today as precipitation spreads across Western Washington. Winds will pick up and become breezy to locally windy behind the warm front this evening.
Snow levels will climb to 8000 to 9000 feet across nearly all of the area by mid to late afternoon. Forecast QPF remains substantial with 36 hour totals 12Z Monday to 00Z Wednesday remaining in the range of 8 to 10 inches for the Olympics, 6 to 9 inches in the north/central Cascades, 3 or 4 inches along the coast, and 1.5 to 3 inches for the most of the interior lowlands outside of the Olympic rain shadow. Sharp river rises and increased risk of river flooding remain a concern later today into Tuesday. See the hydrology portion of the discussion for more on this.
Moderate to heavy rain will continue for much of the region tonight into Tuesday as a slow moving cold front gradually sags southeastward across the area. The axis of the heavier precipitation begins to shift toward Oregon by early Wednesday though a frontal wave may slow its progress southward somewhat.
Snow levels will gradually fall back to most pass levels by Wednesday night as cooler air filters back across the area.
LONG TERM /THURSDAY THROUGH SUNDAY/
Shower activity looks to increase on Thursday as an upper trough axis moves onshore. This should bring some modest snowfall totals to the passes. Models generally retain the idea of a short-lived drying trend later Friday into early Saturday as low amplitude upper ridging slides across the area. Ensembles are generally locked into the idea of another fairly typical fast moving December front arriving over the weekend for more lowland rain and mountain snow. 27
AVIATION
Warm front moving through the area today with the trailing cold front arriving Tuesday. Westerly flow aloft becoming southwest tonight.
KSEA...Ceilings 3000 to 4000 feet lowering to 1000 to 2000 feet with visibility 3-5sm in rain 15z-18z. MVFR ceilings and visibility continuing this afternoon into tonight. East southeast wind 4 to 8 knots becoming southerly 10 to 15 knots with gusts 20 to 25 knots around 00z. Felton
MARINE
A warm front will move through today followed by a cold front Tuesday. Another frontal system will move inland mainly to the south of the waters later Wednesday into Thursday.
High pressure will build over the area Friday.
Gale force winds over the coastal waters as well as the entrances to the Strait of Juan de Fuca today. Gale force winds ending over the coastal waters and West Entrance to the Strait late today.
Gales force winds developing in Admiralty Inlet and over the Northern Inland waters tonight with gales continuing at the East Entrance to the Strait. Small craft advisory winds for the remainder of the waters today and tonight. Winds easing on Tuesday with the only small craft advisory because of winds for the Central Strait of Juan de Fuca. Small craft advisories for the coastal waters because of seas in the 14 to 17 foot range.
Seas peaking Tuesday night near 20 feet before subsiding beginning Wednesday. Seas lowering back down below 10 feet Friday.
Small craft advisory winds possible over the coastal waters Thursday as a system moves inland mainly south of the area. Felton
HYDROLOGY
Atmospheric river aimed at Western Washington for the next 30-36 hours. Rain beginning early this morning along the coast spreading inland reaching the Cascades by mid morning.
Temperatures in the mountains are slowly warming with Paradise at 5400 feet reporting 34 degrees at 3 am. Temperatures are still below freezing in the Central and Northern Cascade passes. Snow levels by late this afternoon will be up to 7500 feet in the Northern Cascades to 8500 feet in the Southern Cascades. Snow levels remaining high tonight, 8500 to 9500 feet before dropping slightly Tuesday to 7000 to 8500 feet.
Once the rain starts this morning over the area it will continue until at least Tuesday afternoon. Rainfall amounts during this time frame remain high, 8 to 10 inches over the Olympics, 6 to 9 inches in the Cascades, 3 to 4 inches along the coast and 1.5 to 3 inches over the interior ( with the exception of the rain shadow northeast of the Olympics ). This amount of rain combined with the rising snow levels will produce river flooding across the area.
Rivers will be on the rise later today and tonight. The Skokomish will be the first river to reach flood stage tonight. The remainder of the rivers predicted to flood will reach flood stage early to mid morning Tuesday. Rivers will crest Tuesday afternoon into Tuesday evening then begin to recede. There is still the potential for moderate flooding on some of the bigger rivers like the Snoqualmie, Snohomish and Skagit with a chance of the Skagit at Concrete and the Snoqualmie near Carnation reaching major flood stage.
There remains a degree of uncertainty in its scope and extent of the flooding. It will depend largely on how fast the air mass warms over the mountains today and the locations of the heaviest bands of precipitation. Stay tuned for the latest forecast developments.
In addition to the river flooding, burn scars in the Cascades will have to be monitored with the heavy precipitation forecast. Elevated risks of landslide and debris flows will also be possible, beginning this afternoon and continuing into Tuesday. The landslide risk could extend into Wednesday. Felton
