NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
301 PM PDT Monday Mar 30 2015 


Synopsis...a cold front will spread rain across the area tonight 
followed by an upper level trough Tuesday for showers and cooler 
weather. Showers will diminish Thursday as weak ridging builds over 
the area ahead of a frontal system that will affect the area on 
Friday. An upper level low will maintain a chance of showers through 
the weekend. 


&& 


Short term...a warm front remains over southern b.C. This afternoon 
with western Washington in the warm sector. As a result...temperatures are pretty 
mild across the region with highs mainly in the 60s. South winds are 
increasing as the cold front starts to slide S/southeast into western Washington. 
This front will bring wetter weather to the region tonight as it 
moves in. Rain will mainly affect the coast this evening...with rain 
spreading into the interior near midnight tonight. There is plenty 
of moisture with this front and we will see wetting rains across the 
board. 


An upper level trough and onshore flow will maintain cool and 
showery weather through Tuesday. Snow levels will drop to around 
3000 feet with a few inches of snow in the mountains. A Puget Sound sound 
convergence zone may enhance amounts in King County. Models also 
show a negative lifted index and cannot rule out isolated 
thunderstorms Tuesday afternoon. Highs on Tuesday will be in the low to middle 
50s - a few degrees below normal. 


The air mass will remain cool and unstable as we head into Wednesday 
with a trough still overhead. Low level onshore flow will prevail 
for scattered showers. The air mass will stabilize and dry out as we 
move into Thursday. By then a weak upper level ridge will build over 
the Pacific northwest. 33 


Long term...the next Pacific frontal system will arrive on Friday 
for another period of wet weather across western Washington. Probability of precipitation were 
nudged upwards as both the GFS and European model (ecmwf) show signs of agreement. 
The forecast through the weekend and into early next week remains 
unsettled as an upper level low spins offshore. This system will 
continue pumping moisture inland for a chance of showers each day. 
The air mass will remain cool with temperatures slightly below normal. 33 


&& 


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


&& 


Aviation...a cold front along 130w at 21z will reach the Washington coast 
around 05z then cross the interior around 09z. Moist westerly 
onshore flow will develop behind the front. Flow aloft will be SW. 
The air mass was fairly dry and stable at 21z with good VFR 
conditions everywhere except for MVFR ceilings along the coast. Ceilings 
throughout West Washington are expected to lower to MVFR tonight in rain with 
and behind the cold front. Gusty S surface winds will develop 
tonight ahead of the front and will be gusty in spots late tonight. 


A broad upper level trough will move over West Washington by Tuesday afternoon 
with the air mass becoming unstable...with showers and a chance of 
thunderstorms. 


Ksea...good VFR conditions are expected through 05z tonight with 
ceilings lowering to bkn030-050 with rain as a cold front reaches the 
area roughly 07z-09z. MVFR ceilings are expected late tonight. Surface 
winds will remain S-SW 6-12 knots through 06z then rise to SW 15-25 knots 
behind the front. Kam 


&& 


Marine...a cold front along 130w at 21z will reach the coast late 
this evening the move across the inland waters a little after 
midnight. Strong onshore flow will develop through the Strait 
immediately behind the front. Tonights forecast was based on the 
morning hrrr model runs which is the only model that is now 
consistently indicating gale force winds in the Strait. The 12z 
Canadian lam also shows a couple of areas of gales. Small Craft Advisory S winds are 
expected over the inland waters and over the coast tonight and 
Tuesday morning. 


Weaker onshore flow will prevail Wednesday and Thursday as a ridge 
builds offshore. There should be enough west pressure gradient through 
the Strait for Small Craft Advisory winds in the evenings. Another cold front will 
probably reach the area Friday. Kam 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...Small Craft Advisory coastal waters...entrances to the 
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.
