NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
350 am PST Sat Jan 31 2015 


Synopsis...upper ridge over western Washington today. Radiational 
cooling and low level temperature inversions will support areas of 
fog over much of the interior lowlands this morning. A series of 
weak systems will bring rain back to the area Sunday and Monday. 
Showers will gradually taper off midweek followed by a transition 
back to a more active pattern late next week. 


&& 


Short term...satellite imagery shows low clouds and fog over much 
of the I-5 corridor from the Canadian border to the Willamette 
Valley...along the north coast and through the Chehalis valley 
(pic0). Locations without the fog and low clouds have mostly clear 
skies. Temperatures were mostly in the middle 30s to lower 40s at 
3am/11z. 


Forecast problem for the day is how long the fog and low clouds will 
last. Sandpoint profiler shows the low level inversion has been 
weakening overnight. Surface gradients are light offshore and with 
an offshore front approaching today the low level offshore flow will 
increase. Current kolm-kbli and kuil-kbli gradients are -1 and -2 
mb. By 00z Monday these numbers will be closer to -2 and -3 mb 
(pic1). Morning pilot report from sea-tac puts the tops between 600 
and 1000 feet. With the increasing offshore flow...weakening of the 
inversion...and the depth of the low level moisture will stay with 
the foggy conditions this morning but go for some sunshine this 
afternoon across The Lowlands. High clouds out ahead of the 
approaching front will reach the area this afternoon so will go with 
partly sunny wording for the afternoon for the most part. Highs will 
be in the upper 40s to middle 50s. 


Warm front moving by to the north of the area tonight (pic2)...close 
enough to have a chance of rain over at least the northern portion 
of the area after midnight. Middle/high level clouds will not be thick 
enough early on to prevent more fog from forming especially in the 
southwest interior. Lows will be mostly in the middle 30s to lower 40s. 


Some differences in the models regarding how fast the offshore 
frontal system will move eastward, the GFS and NAM are the faster 
solutions (pic3) while the European model (ecmwf) remains the slowest of the three. 
Current satellite imagery has the parent low for the frontal system 
way back near 45n/157w (pic5) with the low actually moving westward 
in the last few hours. With the movement of the parent low prefer 
the slower European model (ecmwf) solution. All of the models bring rain into western 
Washington on Sunday. Both the NAM and the GFS move the cold front 
through western Washington Sunday afternoon while the slower European model (ecmwf) 
holds off until Sunday evening. Going with the slower solution will 
have rain at times forecast for Sunday with a rain likely forecast 
for Sunday night. This system is not particularly wet for this time 
of the year with the quantitative precipitation forecast values less than a half an inch for most 
locations. Highs on Sunday near 50 with lows Sunday night with the 
cloud cover only in the lower to middle 40s. 


Another system right on the heels of the one Sunday night moving 
into western Washington on Monday (pic4) keeping rain in the 
forecast. This system is a little stronger than the one for Sunday 
and will produce a little more precipitation as well as breezy 
conditions over the northwest interior. Snow levels will lower down 
to 4000-4500 feet in the mountains. Highs in The Lowlands will once 
again be near 50. 


Long term...there is more general agreement in the extended models 
this morning versus yesterdays 00z run but there are still some big 
inconsistencies for the middle of next week. On Tuesday the European model (ecmwf) 
attempts to build a weak ridge over western Washington while the GFS 
has the ridge further to the west and has a surface low develop over 
Vancouver Island with a weak frontal boundary developing over 
northwest Washington (pic5). On Wednesday the European model (ecmwf) brings a warm 
front up into the area from the south while the GFS doesn't even 
have this feature and instead has a dry forecast with an upper level 
ridge off the coast and low level offshore flow (pic6). There is 
better agreement that beginning Thursday the pattern will turn 
warmer and wetter for western Washington with a pair of systems 
moving through the area Thursday and Friday (pic7)(pic8). Snow 
levels look to be above 5000 feet beginning Thursday rising to as 
high as 7000 feet on Friday. With the differences in the models will 
have to go with chance probability of precipitation for Tuesday and Wednesday. Will stay 
with the rain at times/ rain likely forecasts for Thursday through 
Friday with better model consensus. Felton 


&& 


Hydrology...flooding is not expected through Thursday. 


A series of systems moving by just to the west of the area combined 
with a nearly stalled frontal system around western Washington may 
produce locally heavy rain at times starting later Thursday or 
Friday and continuing through next weekend. This may increase the 
threat of flooding on some area rivers starting Friday or next 
weekend. Snow levels will rise to around 7000 feet by Friday 
Thursday and remain high through next weekend. Albrecht/Felton 


Climate...65 years ago this morning Seattle recorded its coldest 
temperature...0 at Seattle-Tacoma Airport. Felton 


&& 


Aviation...an upper ridge today will give way to a weak front 
Sunday. Light low level offshore flow. Fog in The Lowlands (pic0) 
otherwise just increasing cirrus today. 


Ksea...fog continues. An increase in offshore flow may help push it 
out of the area later this afternoon. 


&& 


Marine...light flow and areas of fog. Stronger offshore flow later 
this afternoon may help to push the fog away (pic1). The fog will be 
done Sunday with stronger flow and a front (pic3)...and another 
front will reach the area Monday (pic4). 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...none.
