NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
330 am PST Monday Jan 26 2015 


Synopsis...high pressure over the region and light surface flow 
will result in widespread low clouds and fog this morning before 
clearing. A weak front will dissipate over western Washington 
Tuesday through early Wednesday. Another ridge will build over the 
region Friday and Saturday giving dry and mild weather. The next 
front brings a chance of rain back into the area Sunday and early 
next week. Near or above temperatures are expected. 


&& 


Short term...high pressure aloft will continue over the region 
today. Light surface flow and near surface based moisture allowed 
for widespread fog to develop across The Lowlands this morning. 
Satellite fog product imagery is obscured by high clouds but most ob 
sites are reporting fog with visibility below one quarter mile 
common. Will issue a dense fog advisory for most The Lowlands 
through late this morning. GFS/NAM buffer soundings both show the 
inversion cap breaking during the afternoon so clearing skies are 
expected. Per usual...the SW interior/S Puget Sound sound will be one of 
the last places to lose the fog which could linger into the early to 
middle afternoon hours. 500 mb heights fall through the day back below 
5700m resulting in slightly cooler temperatures. 
Regardless...expected highs in the middle to upper 50s may break 
records in some places. The record high for sea-tac is 58 and the 
forecast is for 59. 


The upper ridge weakens further and starts to shift east of the area 
tonight. An elongated and diffuse looking frontal system seen on infrared 
satellite imagery will slowly migrate toward western Washington. 00z model runs 
have trended a bit weaker and slower which is not surprising given 
the satellite trends. Deeper moisture arrives at the coast by later 
tonight with a chance of rain. Models show the frontal band 
dissipating as it pushes inland so there is only a chance of some 
spotty light rain on Tuesday. Less than a tenth of an inch is 
expected and some interior locations may not even measure. It will 
be cooler with highs in the low to middle 50s...still above average. 


Models are having a difficult time resolving the weak trailing short 
wave that moves through on Wednesday. Even with the 
inconsistencies...most models indicate some spotty light quantitative precipitation forecast around 
western Washington. It seems prudent to keep the slight risk of showers in the 
forecast for the time being. 


Long term...high pressure aloft builds Thursday through Saturday 
for a period of dry and mild weather. Inversions will likely result 
in some morning low clouds and fog...otherwise mostly clear 
afternoons. High temperatures will be above average in the low to 
middle 50s. 


Long range models show the ridge breaking down Saturday night and 
Sunday as a moist frontal system brings rain back into western Washington. A 
trailing system lifts into b.C. Which may bring additional moisture 
into western Washington beyond Sunday. There is a chance of rain early next week 
and above average temperatures are likely. Mercer 


&& 


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


&& 


Aviation...upper level ridge over western Washington today. Ridge 
axis east of the area with southwesterly flow aloft. Ridge weakening 
tonight as system moves into British Columbia. Air mass stable and moist 
below 1500 feet this morning. 


Widespread visibilities 1/2 sm or less and ceilings 200 feet or less 
at 10z. Surface gradients are light and will continue to be light 
this morning. No top reports yet this morning but Sandpoint profiler 
shows the base of the inversion around 400 to 500 meters so expect 
the tops to be 1000-1500 feet mean sea level. The combination of the shallow 
moist layer and the surface gradients becoming southerly later this 
morning should result in a late morning/midday breakout for most of 
the area. In the fog prone locations like kolm the fog could last 
into the early afternoon hours. Just some high clouds later this 
afternoon into tonight as a very weak system approaches the area. 


Ksea...ceilings at or below 200 feet and visibilities 1/2sm or less until 
middle morning. With the shallow layer rapid improvement late morning 
with just some high clouds by midday. Light winds. Felton 


&& 


Marine...light low level flow this morning. A 1000 mb low will move 
northeast to haida gwaii later today increasing the southerly winds 
over the coastal waters and a few locations over the inland waters. 
The front will dissipate before it moves inland Monday night into 
Tuesday morning. Low level flow will turn onshore Tuesday before 
switching back around to light offshore Wednesday. The light low 
level flow pattern will continue into Friday. Felton 


&& 


Sew watches/warnings/advisories... 
Washington...dense fog advisory through 10 am PST for the lowland zones 
excluding the Strait of Juan Delaware fuca and north coast. 
Pz...none.
