NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
300 am PDT Tuesday Mar 31 2015 


Synopsis...an upper trough will bring showers and cooler weather 
today and Wednesday. Showers will diminish Thursday as weak high 
pressure builds over the area ahead of a frontal system that will 
affect the area on Friday. An upper trough will maintain a chance of 
showers through the weekend. 


&& 


Short term...today will be showery in the wake of a front which 
moved through early this morning. A Puget Sound sound convergence zone is 
likely north of Seattle. Snow levels will drop to near 3000 feet 
today and the mountains should pick up a few inches of new snow. 
Highs will be about 10 degrees cooler than yesterday...lower to middle 
50s. Isolated thunderstorms are possible this afternoon with lifted 
indicies near or slightly below zero and models showing some cape. 


The Puget Sound sound convergence zone is expected to fall apart later 
tonight. There is a chance Stevens Pass could end up getting Snow 
Advisory amounts of new snow by Wednesday morning if the Puget Sound sound 
convergence zone sets up in just the right location. The forecast 
for now is up to eight inches for Stevens Pass today and tonight 
which falls a bit short of advisory criteria. 


The showery pattern will continue Wednesday with an upper trough 
over the area. Showers will probably become a bit more numerous 
Wednesday afternoon with the addition of daytime heating and an 
upper short wave moving through. There will be a slight chance of 
thunder again Wednesday afternoon and highs will again be slightly 
below normal. 


Drier conditions will develop Wednesday night and Thursday as an 
upper ridge moves over the region. The ridge will not be very strong 
and a chance of showers will continue. Schneider 


Long term...a front will reach the area Friday...bringing another 
round of rain. The weekend will be cool and showery with an upper 
trough over the Pacific northwest. Schneider 


&& 


Hydrology...flooding is unlikely over the next 7 days. 


&& 


Aviation...southwest flow aloft over western Washington early this 
morning will veer to westerly today and tonight as an upper trough 
moves across the region. Strong low level onshore flow will ease 
somewhat tonight. The air mass will be moist and unstable. 


There is a mix of high-end MVFR and low-end VFR conditions across 
the forecast area early this morning with areas of light 
precipitation. Conditions will probably lower somewhat this morning 
as moist onshore flow increases...followed by marginal improvement 
this afternoon and tonight. There will be showers during the 
period...with a chance of thunderstorms mainly this afternoon and 
evening. Winds will locally gust to 25 knots today. 


Ksea...the cold front moved through the terminal around 2 am...and 
southwest winds were starting to rise at 3 am. Expect southwest wind 
12-18 knots gusting 25 knots...becoming south 6-12 knots again this evening. 
There is a chance of thunderstorms this afternoon and evening. 
Mcdonnal 


&& 


Marine...strong onshore flow began overnight...and it will prevail 
today in the wake of the cold front that moved into western 
Washington. Race Rocks hit west 40 knots gusting 46 knots at midnight... 
and westerly gales should continue in the central and eastern Strait 
of Juan Delaware fuca into the afternoon. Small Craft Advisory winds are 
likely over the remaining inland waters. 


Weaker onshore flow will continue tonight through Thursday...as high 
pressure sits over the offshore waters. There will be Small Craft 
Advisory winds at times during this period. A weaker cold front will 
move through the forecast area on Friday...followed by onshore flow 
on Saturday. Mcdonnal 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...Small Craft Advisory outer coastal waters for hazardous seas. 
Small Craft Advisory West Entrance Strait...Admiralty 
Inlet...northern inland waters...Puget Sound sound and Hood Canal. 
Gale Warning central Strait of Juan Delaware fuca and East Entrance. 
Small Craft Advisory Grays Harbor for rough bar.
