NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
908 am PDT Tuesday Pep 1 2015 


Synopsis...a weak cold front will bring rain at times to western 
Washington today. A large upper level low will be over the region 
Wednesday through Friday for cool showery weather. The upper level 
low will move east this weekend for a gradual drying and warming 
trend. 


&& 


Short term...a weak cold front is over West Washington this morning... 
extending from central Puget Sound sound across the SW Washington coast. The front 
will continue moving very slowly east and southeast today and should dissipate 
over the Cascades tonight. Rain from the front has been light and 
not that extensive...but that should change this afternoon. An upper 
level shortwave trough offshore near 135w and embedded in the west flow 
aloft will move over West Washington this afternoon. The GFS and NAM show 
precipitation increasing this afternoon and continuing into early this 
evening...particularly on and east of a line from the north Cascades across 
Puget Sound sound and over the central and S coast. 


The cold upper level low over the central b.C. Coast this morning 
will continue moving southeast...reaching southern b.C. On Wednesday. The 
GFS and NAM bring a weak shortwave trough...rotating around the S 
quadrant of the low...over West Washington late this evening for more showers. 


Colder more unstable air that is currently on the west side of the low 
will follow the shortwave trough...moving over the coastal waters 
and West Washington Wednesday morning. GFS shows lifted indices in this cool 
unstable air mass are between -1 and -2...so there is a chance of 
thunderstorms for The Lowlands and Olympics Wednesday afternoon and 
evening. There will likely be isolated thunderstorms over the 
coastal waters and perhaps the coastal strip Wednesday morning. This 
will be added in the next forecast package. 


All models move the cold upper level low slowly S over West Washington on 
Thursday. Scattered showers will continue. The GFS shows small areas 
where lifted indices are just a bit below zero...not quite enough to 
add thunderstorms to the forecast. Maximum temperatures Wednesday and 
Thursday will be in the lower to middle 60s which is about 10 degrees 
below normal. 


With cold air moving S over West Washington Wednesday and Thursday...snow 
levels over the mountains will lower to 5500 to 6000 feet Wednesday 
and 5000-6000 feet Thursday. Along with unseasonably cold 
temperatures the showers could bring several inches of snow to 
higher mountain elevations...particularly the north Cascades. A Special 
Weather Statement remains in effect high-lighting this issue. Kam 


Long term...previous discussion from the 319 am afd...the longer 
range models have fallen into better agreement for the extended 
period Friday through Monday. The upper trough will remain over the 
region Friday...then drier northwest flow will develop Saturday as 
the trough moves east or southeast and continue into Monday. Lighter 
showers Friday will become limited to the Cascades by Saturday 
night...with mostly sunny and warmer weather Sunday and Monday.

&& 


Aviation...a frontal system moving through western Washington this 
morning will produce light rain at times through tonight. Ceilings 
over much of The Lowlands have been ranging between MVFR to IFR with 
the light rain. In addition to rain with the front there have been 
some breezy conditions with gusts up around 20 knots. Expect rain to 
transition to showers later this morning as the front exits the 
area. The higher terrain will remain obscured today. The areas of 
breezy southerly wind will decrease overnight and Tuesday morning as 
the front weakens. 


Ksea...rain band associated with the front over the terminal as of 
16z. This band will slowly work east this morning allowing ceilings 
to improve to MVFR and then VFR this afternoon. Rain will give way 
to showers as the front works east. Southerly winds 6 to 10 knots. 


&& 


Marine...a frontal system moving through western Washington this 
morning bringing rain to area waters. Increasing southwesterly winds 
over the coastal waters today will become westerly this afternoon 
and evening. A Small Craft Advisory remains in place for parts of 
the coastal waters and Grays Harbor bar through Wednesday morning. 
A broad trough in the northeast Pacific will gradually sag over the 
pacnw and weaken over the next several days and then weak high 
pressure will build late in the week. 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...small craft advisories northern and central outer coastal 
waters...Grays Harbor bar.
