NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
846 PM PDT Monday Apr 20 2015 


Synopsis...an upper level ridge will keeps skies mostly clear 
tonight. Weak low level onshore flow overnight will allow a few 
areas of low clouds to form over western Washington Tuesday morning. 
A weak front will bring clouds and a few showers to the coast late 
Tuesday morning and then over Puget Sound sound late in the day. An upper 
level trough will follow Tuesday night and Wednesday morning. 
Another weak front will bring a few showers on Thursday. Moist 
southwest flow aloft will bring periods of rain next weekend. 


&& 


Short term...the upper level ridge over West Washington this evening will 
shift over north Idaho Tuesday morning...allowing the weak front just 
offshore near 130w to move toward the Washington coast. Onshore flow is 
increasing this evening ahead of the front...which is very 
reminiscent of a Summer-time pattern. There was just a little ribbon 
of stratus along the central coastline late this afternoon and 
onshore pressure gradients have only made it up to 1.0 to 1.5 
mb...so it does not look like there will be a whole lot of stratus 
forming in place over the interior Tuesday morning. Best guess is 
areas of stratus through the Strait and over the lower Chehalis 
valley mainly west of Shelton. 


The weak front along 130w this evening will reach the area on 
Tuesday. Models have the leading edge of the frontal clouds reaching 
the coast around late Tuesday morning...and Puget Sound sound late in the 
afternoon. The front should be over the Cascades by late evening. 
Frontal precipitation will be pretty skimpy...with light 
accumulations on the coast mainly upstream of the Olympics. Over the 
interior it looks like most of the precipitation will be around central 
Puget Sound sound where a convergence zone is expected to form...and over 
the Cascades where low level west winds will generate upslope flow. 


An upper level trough will be right behind the front...crossing 
Puget Sound sound early Wednesday morning...then moving over East Washington 
Wednesday afternoon. NAM high res soundings indicate the air mass 
will remain stable with both the weak front and the associated upper 
level trough. Precipitation on Wednesday behind the upper trough should be 
mainly associated with the convergence zone...and those showers 
should be diminishing by afternoon. 


It looks like Wednesday afternoon and evening will be mostly dry. A 
small weak upper level shortwave ridge will move across the 
area...but the break will be mostly due to The Gap in-between 
weather systems. 


GFS and European model (ecmwf) agree that a weakening cold front will reach West Washington on 
Thursday. This would be the system currently far offshore near 170w. 
This system could bring a little more widespread precipitation than 
tuesdays system...but still on the light side. Kam 


Long term...models agree that a weak upper level trough will move 
across the area Friday...followed by a weak ridge Friday night. 
Scattered showers associated with the trough should diminish Friday 
night. 


A large cold upper level longwave low will set up over the NE 
Pacific this weekend with strong flow aloft around the low. Moist 
west-southwest flow aloft over the NE Pacific east of the low will be aimed at the 
pacnw. This looks like potentially the wettest period for West Washington since 
middle March. Kam 


&& 


Aviation...the upper level ridge over the region will weaken as the 
ridge axis shifts east of the Cascades overnight. A weak cold front 
is on track to move through the forecast area Tuesday 
afternoon...followed by an upper level trough Tuesday night. This 
will result in a short period of rain followed by showers Tuesday 
night. Northwest flow aloft will become southwest late tonight as 
the upper level trough approaches from the west. The air mass will 
become moist late tonight and Tuesday as low level onshore flow 
increases. 


Marine stratus along the coast will deepen and push inland tonight. 
The push continues to look weak...the current forecast reflects 
stratus reaching Olympia late tonight with any low clouds reaching 
the central sound remaining thin and relatively short lived Tuesday 
morning. 


Ksea...north wind to 10 knots...becoming southerly to 8 knots late...then 
southwest 6-12 knots Tuesday afternoon. Thin marine stratus will likely 
reach the terminal around 13z with several hours of scattered-bkn005 
Tuesday morning. 


&& 


Marine...onshore flow will strengthen tonight as low pressure over 
western Washington moves east of the Cascades. Small Craft Advisory 
winds remain forecast for the coastal waters...western and central 
Strait of Juan Delaware fuca...Admiralty Inlet...and northern inland 
waters. The strongest winds should occur in the central and eastern 
Strait. 


Onshore flow will continue to increase Tuesday and Tuesday night as 
a weak cold front moves inland. Gale westerlies remain likely for 
the central and eastern Strait. A gale watch remains in place for 
the potential for marginal gales over the northwest coastal waters. 
Small Craft Advisory winds will continue for all other marine zones 
except Puget Sound sound and Hood Canal. 


A second weak cold front will cross the forecast area Thursday and 
Thursday night...with a stronger frontal system expected to reach 
the area Saturday.

Sew watches/warnings/advisories... 
Washington...none. 
Pz...Small Craft Advisory coastal waters...central and eastern 
Strait of Juan Delaware fuca...Admiralty Inlet...northern inland
