NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
300 PM PDT Friday may 29 2015 


Synopsis...thunderstorms are possible in the mountains today as 
western Washington has another hot day. Slight cooling is likely 
over the weekend as night and morning stratus increases...though 
high temperatures will remain above normal. An unsettled and cooler 
pattern will arrive next week. 


&& 


Short term...so far thunderstorms are along the crest and eastward. 
Will keep a chance of thunderstorms in the Cascades and east Puget Sound 
sound lowlands this evening. Altocumulus castellanus that was widespread this morning 
has mostly dissipated except for over the northern Cascades. Stratus 
has retreated to the coast. Should be a mostly clear night...then 
marine stratus will spread inland late. 


Onshore gradients are higher than yesterday so morning stratus will 
be more widespread. This will give some cooling as well...from highs 
in the low 80s today to the 70s Saturday. The weak impulse that is 
giving scattered thunderstorms to the Cascades today will be well to 
the east on Saturday so probability of precipitation are near zero. 


Stratus will retreat to the coast Saturday afternoon and spread 
inland overnight again. Sunday will be similar to Saturday with one 
exception...high and middle level clouds will increase from the south. 
Highs on Sunday will again be in the 70s. 


The upper low off Oregon will move closer on Monday. Not only will 
this spread moisture into Washington...but heights will fall and the 
pattern is favorable for thunderstorms. Have limited thunder to the 
Cascades for now but it seems possible anywhere. Highs on Monday 
will fall into the 60s as a cooler and wetter pattern begins. Burke 


Long term...Tuesday looks like the wettest day as the upper low is 
right over western Washington. Probability of precipitation are likely or better. High 
temperatures will be mainly in the low 60s. Conditions slowly 
improve as the week wears on but the overall pattern is still 
troughy and there will be a chance of showers each day through 
Thursday. By Friday heights are building and the shower chance 
should be confined to the Cascades. Temperatures will also rise and 
by Friday should be back to normal or even a few degrees above 
normal. Burke 


&& 


Aviation...mainly dry west flow aloft will prevail over West Washington tonight 
and Saturday...between an upper level low centered over central 
British Columbia and an upper level ridge over the SW U.S. A 
surface ridge over the NE Pacific will maintain low level onshore 
flow. 


Stratus has dissipated almost to the coast this afternoon with good 
VFR conditions over the rest of West Washington. The unstable air mass over the 
Cascades has produced thunderstorms this afternoon...but SW flow has 
been keeping development east of the crest. There is still a small 
chance of isolated cells developing west of the crest through 03z. 


Onshore flow tonight will spread marine moisture back inland over 
the interior overnight. SW pressure gradients at 21z were about 1.3 
mb ahead of yesterday with hqm-sea and AST-sea at 2.3 mb and 1.9 mb 
respectively. This should help spread stratus farther inland 
Saturday morning than this morning...with slightly higher ceilings 
between ovc005-015. Burn-off should occur by around 18z with good 
VFR conditions the rest of Saturday. 


Ksea...good VFR conditions are expected through tonight with just 
high level clouds over the area. There will be isolated 
thunderstorms over the Cascades through roughly 03z. Surface winds 
will remain west-SW 4-8 knots through 07z. Onshore flow will redevelop 
overnight and IFR stratus is expected to reach the terminal around 
12z...then dissipate around 18z. Kam 


&& 


Marine...a surface ridge parked offshore...combined with lower 
pressure over East Washington will maintain weak to moderate westerly onshore 
flow through this weekend. The main question is how strong the 
onshore flow will become tonight and Saturday night in the Strait of 
Juan Delaware fuca. The uil-bli pressure gradient peaked at 2.1 mb last 
night...generating 30 knots at Race Rocks. This afternoon the gradient 
has not eased as much and the gradient and wind speeds are ahead of 
yesterday. The Canadian 2.5 km lam model still caps winds at 25-30 
knots and Canadian statistical guidance for Race Rocks holds the peak 
wind at 32 knots. The coordinated forecast with Environment Canada will 
stick with 20-30 knots in the Strait tonight but a brief Race Rocks 
gale is not completely out of the question. 


Moderate flow through the Strait is also expected Saturday 
night...but the models have been inconsistent with the strength of 
the pressure gradient...so I will keep the forecast at 20-30 knots for 
now. 


An upper level low will move over the region early next week which 
will shift the low level onshore flow direction to SW starting 
Monday morning. Kam 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...Small Craft Advisory central and eastern Strait.
