NWS Forecaster Discussion




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


Synopsis...increasing onshore flow will bring marine stratus into 
portions of western Washington late tonight and Saturday morning. 
Sunshine should prevail Saturday afternoon with moderating high 
temperatures...then warming a few degrees on Sunday. An upper level 
low off the California coast will lift northeast into the area 
Monday and Tuesday. Showers and a chance of thunderstorms are 
expected along with a cooling trend. Unsettled weather may continue 
through Thursday...then drying out toward the end of next week. 


&& 


Short term...onshore flow is stronger again tonight with over +3 mb 
through the Strait and oth-sea gradient up to +3.8 mb. Stratus along 
the coast should spread down the Strait overnight and also through 
the Chehalis gap reaching Shelton and Olympia before dawn. Gradients 
should be strong enough to spread shallow stratus into Puget Sound sound 
entering the north sound from the eastern Strait and the S/central sound 
from the southern weak surge. MOS is mixed on whether stratus reaches 
sea-tac but a few hours of low clouds after sunrise seems likely. 
Low clouds will burn back to the coast by afternoon with filtered 
sunshine given lots of high clouds over the area. Highs will cool 
back to the low and middle 70s around Puget Sound sound and only in the low 
60s near the coast and Strait at best. 


Models have trended toward a somewhat stronger ridge for Sunday with 
lighter west-northwest onshore flow. Morning stratus may be more limited and 
patchy across the interior with high temperatures warming a few 
degrees. Models show moisture advection in the middle/upper levels with 
a warm and weakly unstable air mass aloft. There could be some ac 
clouds around but probably too shallow a layer for much convective 
development. 


The air mass aloft remains unstable Sunday night and Monday with 
some threat of thunderstorms just about anywhere. The current 
forecast has thunder over the Cascades which is fine for the time 
being but isolated thunder may need to be expanded over The Lowlands 
if models continue to look convective. An upper level off the California 
coast will be moving NE and will bring deeper moisture into the area 
later Monday and Monday night with a better chance of showers and 
possibly thunderstorms. 


Long term...no change from previous discussion...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...an upper level low over central British Columbia 
combined with a ridge over the desert SW will give light SW flow 
aloft. The air mass is stable with some high level moisture and 
marine moisture along the Washington coast. 


The combination of heating in the interior...convection east of the 
Cascades...and the upper level low to the north has tightened 
onshore pressure gradients this evening. With the increased onshore 
flow...expect stratus to surge farther inland overnight...and be 
deeper and a little more persistent into midday Saturday. The 00z 
nam12 shows a 5-7 hour period of stratus in the Seattle area Sat 
morning with bases around 010 and tops 020...consistent with coastal 
observations and the strength of the onshore flow. Stratus will move 
in earlier around the Strait of Juan Delaware fuca and the Chehalis gap. 


The air mass on Saturday over the mountains will be more stable than 
the past several days...and afternoon and evening convection is not 
expected in the Cascades. Albrecht 


Ksea...good VFR conditions are expected through tonight with just 
high level clouds over the area. Stratus will move into the terminal 
around 12z and persist until about 19z. At this time it appear that 
ceilings will settle in around 007 and visible around 5sm br. Expect SW wind 
4-6 knots through Sat. Albrecht 


&& 


Marine...a surface ridge well offshore combined with lower pressure east 
of the Cascades will give onshore flow through the weekend. Inflow 
through the Strait is strongest today and is expected to be somewhat 
weaker Sat through sun. 


While winds have been slow to increase this evening...the kuil-kbli 
gradient of +3.4 mb suggests that gales will develop this evening. 
Will maintain the Gale Warning for the central and eastern Strait of 
Juan Delaware fuca and the Small Craft Advisory for Admiralty Inlet and 
the northern inland waters. Winds and seas will gradually diminish 
during the early morning hours on Sat. 


An upper level low moving in from the southwest will induce a 
southwesterly marine push Monday morning. Albrecht 


&& 


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