    A small but vigorous cell was producing isolated heavy showers and lightning over north Seattle and Kirkland at 835 PM. The cell will probably weaken over the next 30 minutes or so as it moves east...but a few more lightning strikes and heavy showers are possible as it moves from the Seattle metropolitan area into the east Puget Sound lowlands.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
900 PM PDT Friday Oct 31 2014 


Synopsis...an upper trough will move into western Washington 
tonight and Saturday...for mainly dry weather with a little sunshine 
Saturday. A weak ridge will move inland Saturday night...and then a 
warm front will bring some rain Sunday and Sunday night. A stronger 
frontal system will bring rainy and locally windy weather Monday and 
Tuesday...and the wet pattern will probably continue next week. 


&& 


Short term...we have southerly flow aloft over western Washington 
this evening ahead of an elongated upper trough approaching the 
region from the offshore waters. Skies were partly cloudy to cloudy 
across the forecast area at 8 PM with only isolated showers. However 
a cell that developed over the north Kitsap peninsula earlier this 
evening produced locally heavy showers and isolated thunder and 
lightning as it moved across north Seattle...Lake Washington...and 
Kirkland just after 8 PM. The tops on this cell were only around 
13000 feet. It should weaken over the next 30 minutes as it continues 
east...and we do not expect this activity to become more widespread. 
We issued a Nowcast for it. 


The upper trough will move to the Pacific northwest coast late 
tonight and then inland on Saturday. As mentioned above the trough 
is elongated...and the core of it will be digging southeast across 
California. The northern portion heading into western Washington 
will be weak...so any showers it produces should be light and 
spotty. Most of western Washington will have partly sunny skies on 
Saturday. 


A flat upper ridge will move into the offshore waters Saturday night 
and then progress inland on Sunday. A weak warm front immediately 
upstream of the ridge axis will move into the forecast area Sunday 
or Sunday night. The timing of this feature is still somewhat 
uncertain...and it will probably be weakening as it moves inland. 
The coast will probably have some rainfall on Sunday but the 
interior could remain dry until late in the day or even Sunday night. 


A stronger and wetter frontal system will move into western 
Washington Monday and Monday night. This system should result in 
breezy to locally windy conditions and fairly significant 
precipitation. The snow level will rise to around 7000 feet. Mcdonnal 


Long term...here is the long term section from the afternoon 
forecast discussion -- global models agree on a wet pattern next 
week. The warm front moving through on Monday will be followed by a 
moist cold front. Some model runs including the 12z GFS show the 
main frontal band stalling over western Washington Monday night into Tuesday 
with locally heavy rain. See Hydro discussion below. 


Models diverge on the pattern by Wednesday. The European model (ecmwf) maintains the 
wet southwesterly flow pattern while the GFS is dry with more ridging. Other 
models like the Canadian show some break in precipitation but bring 
rain back into the area later in the day. Regardless...wet weather 
will resume Thursday and Friday as a stronger area of low pressure 
tracks near or to the north of western Washington. Both the Canadian/European model (ecmwf) show a 
deeper low closer to our area which bares watching as breezy or 
windy conditions are possible. Mercer 


&& 


Hydrology...a Pacific frontal system will bring around 2 to 4 
inches of rain...and locally perhaps 5 inches...to the Olympic 
Mountains Sunday night through Tuesday. Flooding is possible on the 
exceptionally flood-prone Skokomish River if that occurs. 


Flooding is unlikely on all other rivers in our forecast area for 
the next 7 days. 


In addition...recent heavy precipitation amounts have created 
antecedent conditions favorable to landslides in western 
Washington...according to the USGS landslide hazards program. In 
fact...precipitation for the month of October at SeaTac is around 
190 percent of normal...and this will probably be the third wettest 
October on record at SeaTac. The threat of landslides will be 
something to watch as a wet weather pattern continues. Mcdonnal 


&& 


Aviation...there was a thunderstorm over Northern Lake Washington at 830pm...we 
had a downpour here at the National Weather Service and there was a lightning strike in 
Kirkland. Southwest flow aloft will weaken and become light 
northwesterly Saturday afternoon as a weak upper trough moves 
through the area. The air mass is slightly unstable and moist with 
scattered showers which will end overnight. Slow drying of the air 
will occur tonight and Saturday with partly sunny skies on Saturday. 


Ksea...a shower over the northern half of Lake Washington generated a 
lightning strike over in kirland around 830pm...with tops around 
13kft that was probably a one flash storm. The showers were moving 
east. The current taf looks like a good forecast although with light 
pressure gradients there is a chance that some rather low stratus 
could set up overnight. Fog isn't likely but we may see a period of 
3sm br around daybreak. 


&& 


Marine...pressure gradients are light this evening. The weak trough 
just offshore has pretty much dissipated now. Weak high pressure 
will build Saturday. Stronger systems are likely next week beginning 
Sunday. Small Craft Advisory winds are in the grids and forecasts 
for several periods centered around Sunday night and again 
Wednesday. 


&& 


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