NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
830 PM PST Wednesday Jan 28 2015 


Synopsis...a weak upper disturbance will move inland tonight for 
isolated light showers. An upper ridge will provide dry and mild 
weather Thursday through Saturday. A front will bring rain back to 
the area Sunday and early next week. 


&& 


Short term...a broad upper ridge will be over the area tonight with 
low level offshore flow. A weak disturbance in the southwest flow 
aloft could bring some sprinkles tonight but this is looking less 
and less likely based on radar along with the fact the latest nam12 
and hrrr models which show dry weather all night. There will 
probably also be some fog tonight although clouds coming up from the 
south will likely prevent this from becoming too prevalent. 


The upper ridge will remain over the area Thursday through Saturday 
for dry weather. Low level offshore flow will also prevail during 
this period. Highs will be a little above normal each day...mostly 
in the 50s...with a slight warming trend through the period. 
Schneider 


Long term...previous discussion...a warm front will bring some rain 
to the area on Sunday as it moves inland. But this system is looking 
slower and weaker with each new model solution. A wetter Pacific 
frontal system will then reach the area on Monday for another shot of 
rain. Snow level are a little lower with this system around 
4000-5000 feet. The GFS tries to build another ridge over the region 
Tuesday and Wednesday. The European model (ecmwf) however steers some moisture our way for 
wetter weather pattern. Confidence remains low at this point. 33 


&& 


Hydrology...flooding is not expected for the next 7 days. 


&& 


Aviation...a weak upper level ridge will remain over western 
Washington tonight and Thursday. A surface ridge over East Washington will 
maintain weak low level offshore flow. The air mass is generally dry 
and stable...but surface temperature-dew point depressions at 04z 
were 5f or lower just about everywhere so some patchy fog and low 
stratus can be expected 08z-18z. 


A very weak upper level shortwave trough just west of the north Oregon 
coast at 04z will move NE across West Washington tonight through 20z. This 
shortwave will spread bkn050-100 cloud layers across West Washington 
overnight...making it more difficult for fog/low stratus to form. A 
clearing trend for the shortwave trough moisture and whatever 
fog/stratus forms is expected after 18z. 


Ksea...VFR conditions are expected tonight. Middle level clouds 
scattered-bkn050-100 should be present 09z-18z which should be enough to 
prevent fog and low stratus from forming. However with 
temperature-dew point depressions expected to reach 2-3f...some 
patchy stratus is not completely out of the question. Surface winds 
will be north-NE 3-7 knots. Kam 


&& 


Marine...a weak surface ridge centered over eastern Washington will 
maintain weak offshore flow through Saturday. Pressure gradients 
across western Washington will remain weak...producing northerly 
winds along the coast and through Puget Sound sound...and easterly winds 
through the Strait. Winds are expected to remain less than 20 
knots. The exception is the West Entrance where easterly winds will get 
into the 15-25 knots range at times tonight and Thursday morning...and 
possibly some other days as well. 


Models bring a weak front through the area Sunday. Latest runs show 
winds mostly staying below Small Craft Advisory levels with this 
front. A stronger system will follow on Monday and the Small Craft 
Advisory winds appear to be associated more with this system. 
Chb/kam 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...Small Craft Advisory West Entrance.
