NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
340 PM PDT Tuesday Oct 21 2014 


Synopsis...a strong frontal system will bring wind and rain to the 
coast tonight and to the interior of western Washington late tonight 
into Wednesday morning. Very heavy rainfall is possible along the 
southwestern Olympic Mountains tonight into early Wednesday and to 
the north Cascades late tonight through Wednesday. Showers will 
continue Wednesday night through Thursday as southwest flow aloft 
persists. A low pressure system will give rain and windy weather to 
the area Friday night through the weekend. 


&& 


Short term...the upcoming week will be quite active as a series of 
systems move through the Pacific northwest. The jet across the North 
Pacific is becoming rather strong as cold air dumps out of the 
Bering Sea into the Gulf of Alaska and subtropical and tropical 
moisture and energy from systems in the central North Pacific gets 
entrained into the flow. 


An occluded front sits from central Vancouver Island southwestward 
into the Pacific. The air mass this afternoon over the coastal 
waters continues to be quite unstable and there is a good deal of 
lightning being observed 40 to 70 miles off the north coast. Some 
thunderstorm activity may clip the north coast this evening...but 
the air mass is likely to become a bit more stable later tonight as 
overrunning develops ahead of the incoming developing low. 
A developing wave now seen near 46n 142w will develop to a 992 mb 
low as it moves into south central Vancouver Island late tonight. 
This low is developing in the left exit region of a 150 knots 300 mb 
jet that is charging eastward across the east central North Pacific 
and has been charged with subtropical moisture from an upper trough 
now seen near 37n 165e. 


Two issues are likely with this low tonight...wind and heavy 
rainfall. Wind is likely to reach 20 to 35 miles per hour with gusts to 50 miles per hour 
along the coast tonight and 20 to 30 miles per hour with gusts to 45 miles per hour 
through the north interior from about Admiralty Inlet northward late 
tonight into Wednesday morning. A Wind Advisory was issued last 
night and will be maintained. Quantitative precipitation forecast from the 18z nam12 shows 3 to 6 
inches of rain over the southwest facing Olympics through tonight 
and another inch or two early Wednesday morning. The 12z wrfgfs 
shows up to 10 inches of rain tonight into Wednesday morning in the 
Rain Forest areas of the SW olympic peninsula...quite impressive. 
This heavy rain appears to be due to a combination of convection and 
strong upslope flow with south-southwest winds 55 knots at 850 mb. Rainfall is 
expected to be heavy very late tonight into Wednesday evening over 
the north Cascades...and the latest wrfgfs shows several inches of 
rain on the west slopes of The Mount Baker area in Whatcom County 
and the mountains northwest of Darrington. 


A Flood Watch is in effect through Wednesday for the olympic 
peninsula. The Flood Watch has been expanded and extended to include 
rivers flowing off the north Cascades from Snohomish County 
northward midday Wednesday through Wednesday night. 


The front is progressive and will push eastward reaching from the north 
Cascades to the northwest Oregon coast Wednesday afternoon. Then rain becomes 
showery from the northwest Wednesday evening as the front continues to slowly 
push southeastward. 


Breezy and showery weather can be expected Wednesday night through Thursday in 
strong SW flow aloft. 


Large scale models continue to show development of a rather deep low 
off the northern California coast Thursday night into Friday as 
energy dumping southward from the Bering Sea into the North Pacific 
phases somewhat with the remains of Hurricane Ana that has recently 
impacted western Hawaii. The models vary significantly in the 
eventual structure of this developing system and where it moves 
inland on Saturday. It is a good bet that Saturday will be wet and 
windy over western Washington. This system will need to be carefully 
monitored. Albrecht 


Long term...the offshore low moves inland somewhere over the 
Pacific northwest on Saturday bringing wet and windy weather to the area. 
Post frontal showers decrease on Sunday...then another warm front 
and low appear to be on track to move across the area Monday and 
Tuesday. Model details differ...but it appears that next week will 
be wet and breezy with mountain snow levels decreasing to at least 
higher pass level midweek and temperatures in The Lowlands cooling 
off where highs struggle to get out of the lower to middle 50s. Albrecht 


&& 


Hydrology...flood watches are now in effect for the olympic 
peninsula tonight and Wednesday...and for Snohomish County northward 
in the interior from midday Wednesday into Wednesday night. 


The Skokomish River is likely to see moderate flooding. If the 
heavier precipitation seen in the wrfgfs 4km verifies...the 
Skokomish River at Potlatch could see major flooding during the day 
Wednesday. Other rivers flowing off the Olympics such as the 
Quinault...Clearwater...Hoh...and bogachiel could see minor 
flooding late tonight into Wednesday. 


Based on latest rainfall forecasts...portions of the stillaguamish 
river in Snohomish County and the Nooksack river in Whatcom County 
could see minor flooding later Wednesday or Wednesday night. Rather 
intense rainfall on Wednesday may also cause small streams and 
uncontrolled rivers in the north Cascades to rise rapidly and 
possibly flood. Albrecht 


&& 


Aviation...westerly flow aloft becoming southwest tonight. A 
vigorous frontal system will move into the area later today and 
tonight...bringing rain and wind. Air mass moist and stable. 


Ceilings mostly 4000-7000 feet with some peeks of sun east of Puget Sound 
sound the remainder of this afternoon. Lower ceilings expected in 
scattered showers as they spread eastward from olympic peninsula. 
Ceilings expected to gradually lower tonight as steady rain develops. 


Ksea...generally middle level clouds for the remainder of the afternoon 
and into early evening. Ceilings should gradually lower tonight as 
rain develops. South wind 10 to 15 knots...increasing to 10 to 20 
knots Wednesday morning. Schneider/smr 


&& 


Marine...a vigorous frontal system will bring gale force winds to 
most waters over the next 24 hours with Small Craft Advisory winds 
expected in the central Strait and Puget Sound sound. 


There will be a relative lull in the stormy weather in the middle of 
the week...then another strong weather system will affect the waters 
Friday and Saturday. A deep surface low is expected to track through 
the waters during this time but there is still a lot of uncertainty 
with how strong the low will be and where it will go. Schneider/smr 




&& 


Sew watches/warnings/advisories... 
Washington...Flood Watch Mason...Clallam...Jefferson...and Grays Harbor 
counties tonight into Wednesday afternoon. 
Flood Watch Snohomish...Skagit...and Whatcom counties midday 
Wednesday through Wednesday night. 
Wind Advisory coast...Admiralty Inlet...San Juans...western 
Whatcom...western Skagit. 


Pz...Gale Warning coastal waters...entrances to the Strait of 
Juan Delaware fuca...northern inland waters...and Admiralty Inlet 
late through tonight. 
Small Craft Advisory central Strait of Juan Delaware fuca and 
Puget Sound sound and Hood Canal. 
Small Craft Advisory gray Harbor Bar for rough bar.
