NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
400 am PDT Wednesday Apr 23 2014 


Synopsis...showers will persist this morning before a warm front 
begins to spread rain into western Washington from the south this 
afternoon and tonight. A cold front will move inland Thursday 
morning. An upper level trough digging into the Pacific northwest on 
Friday will keep scattered showers in the forecast. A third frontal 
system will bring another round of more organized rainfall to the 
area Saturday afternoon into Sunday morning. 


&& 


Short term...showers associated with the upper level short wave 
trough that has been working through the Pacific northwest overnight 
have tapered off somewhat over the last few hours. Expect the 
showers to continue to decrease as the upper level trough lifts into 
British Columbia this morning. The break will be shortlived as rain 
will increase from the southwest during the afternoon as a warm 
front moves into the area. The warm front will bring more organized 
rainfall to the area...followed by the cold front Thursday morning. 
Rain will transition to showers Thursday afternoon with moist and 
somewhat unstable southwest flow aloft behind the front. Expect 1 to 
2 inches of rainfall Wednesday evening through Thursday afternoon 
over the Olympics and the central Washington Cascades near Mount 
Rainier. The coast will see 0.5 to 0.75 inches and the interior up 
to 0.5 inches over the same period. Decent southerly surface 
gradients behind the front will produce breezy winds. 


An upper trough will dig into the Pacific northwest on Friday 
keeping a chance of showers over the region. The good news is 
showers will be spotty and not organized with a decent amount of 
sunshine in between showers. 


Long term...the active weather pattern will continue into early 
next week. The digging upper level over the West Coast will keep 
showers across western Washington on Saturday. A frontal system will 
move inland Saturday evening bringing another round of organized 
rainfall. Onshore flow and zonal flow aloft on Sunday will keep 
showers mainly over the coast and the mountains. Another frontal 
system will affect the region Monday or Monday night with medium range 
models hinting at an upper level ridge building over the region on 
Tuesday for drier and warmer weather. 


&& 


Hydrology...river flooding remains unlikely for the next 7 days. 


The exception remains the North Fork of the stillaguamish river east 
of the sunrise 530 landslide near Oso where a Flood Warning remains in 
effect until further notice. Flooding continues for this river as a 
result of water pooled behind the debris dam that partially blocks 
the river. 


At 315 am...the North Fork of the stillaguamish near Arlington was 
at 4.65 feet...or 2889 cfs. The North Fork of the stillaguamish river 
near Oso was at 216.4 feet at 1841 cfs. The pool east of the slide was 
282.5 feet at 315 am this morning. 


A warm front will spread rain into the area tonight...followed by a 
cold front Thursday morning. This system will bring around 1.00 inch 
of rainfall to the area through Thursday afternoon. This is expected 
to produce rises on the stillaguamish river beginning Wednesday 
evening through Thursday...cresting Thursday evening around 10 PM at 
just over 5 feet. 


&& 


Aviation...a trough will move east of western Washington today with a break 
between weather systems. Another stronger low pressure system will 
affect the region tonight into Thursday. Moderate SW flow 
aloft...becoming strong tonight. Moist and somewhat unstable 
becoming stable tonight. Decreasing showers this morning...then 
increasing rain late this afternoon and evening. A mix of VFR and 
2-3k feet MVFR ceilings this morning...then VFR above 4k feet. Warm 
frontal rain tonight should produce widespread MVFR ceilings. 


Ksea...variable ceilings between MVFR and VFR due to showers through 
16z...then mostly VFR. MVFR ceilings and visible should dominate tonight 
with steady rain. S wind 4-8 knots...becoming SW 10-15 west/ gusts to 25 
knots later tonight. 


&& 


Marine...there will be a lull in winds today ahead of the next 
stronger low pressure system. Southerly winds over the coastal waters will 
vary in strength through the day topping 20 knots at times west/ swell 
around 10 feet. Therefore...a Small Craft Advisory remain up for the 
coast. Winds elsewhere below 20 knots today. A 990 mb low will track NE 
outside the outer coastal waters into Vancouver Island tonight. The 
track is close enough so that high end small craft winds over the 
coast and West Entrance are likely...possibly reaching gale force at 
times from this evening through Thursday morning. A gale watch 
is in effect tonight and Thursday morning for the coast/West Entrance 
but kept winds to 30 knots in the forecast for now given the 
uncertainty. Small craft winds should develop over the remaining 
waters tonight into Thursday...then ease. 


A lull in winds expected Friday...then more widespread small craft 
winds possible with the next system on Saturday. 


&& 


Sew watches/warnings/advisories... 
Washington...Flood Warning remains in effect for the North Fork of the 
stillaguamish river east of the sunrise 530 landslide. 


Pz...Small Craft Advisory coast through this afternoon. 
Gale watch coast and West Entrance to the Strait of Juan Delaware 
fuca from 5 PM PDT through Thursday morning.
