NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland 
326 am PDT Sat Apr 25 2015 


Synopsis...upper level low pressure continues to bring cool and 
unsettled weather to the Pacific northwest. Expect valley rain and 
mountain snow showers to continue today. Any heavier showers may 
produce small hail and lightning...especially early this afternoon. 
The upper low will weaken and move east by this evening...with high 
pressure bringing a swift end to any lingering showers. A warm front 
may clip the region with some light rain Sunday and Sunday night... 
mostly along the north coast. Monday will be drier and much warmer as 
a strong upper level ridge builds in from the south. The next cold 
front may bring more showers as early as Tuesday...with more showers 
possible for the rest of the week as another upper level trough 
settles near the Pacific northwest. 


&& 


Short term...today through Monday...National Weather Service Doppler radar continues to 
show several showers moving across SW Washington and northwest Oregon this 
morning...as the air mass remains cool...moist and unstable due to an 
upper level low centered over Vancouver Island. One last lobe of cool 
air aloft is expected to pivot across the forecast area around midday 
today...combining with occasional sunshine to produce another spike 
in shower activity this morning into middle afternoon. 


With 500 mb temperatures around -30 degree c within the cool core aloft...the 
potential exists for somewhat deeper convection than Friday. A few 
stray claps of thunder were reported Friday...even with milder air 
aloft. Therefore the potential exists for isolated thunderstorms 
today...especially north of Salem. With freezing levels hovering in 
the 4000-5000 feet range...heavier showers should also have an easy 
time producing small hail. Shear profiles look weak and cape is 
minimal...so we do not expect anything to approach severe limits. 


The Cascades have already received a few inches of snow...with as 
much as 6-8 inches being reported at timberline since Thursday. A 
couple more inches could accumulate from snow showers today...but 
accumulations will be spotty. Some wet snow is expected at pass 
level...though the strong April sun will probably melt most snow off 
the roads by mid-morning. 


Instability will come to a quick end from top to bottom later this 
afternoon and evening...as temperatures warm aloft and cool at the surface 
with the loss of solar heating. Meanwhile high pressure will build 
across SW Washington/northwest or...bringing subsidence. This should bring a swift 
end to any lingering showers this evening. Some valley fog is 
possible if skies stay clear tonight...but high clouds ahead of an 
approaching warm front will probably make it difficult for fog to 
become too widespread tonight and Sunday morning. 


Models are finally showing some agreement that the warm front will 
brush the north coast with some rain while much of the Willamette 
Valley and Oregon Cascades remain dry. Much warmer air behind the 
front will cause a sharp increase in temperatures Monday. With 850 mb temperatures 
forecast to be in the +12 to +14 degree c range...temperatures inland could push 80 
degrees in the valleys. Weagle 


Long term...Monday night through Friday...models continue to 
struggle with the details Tuesday and beyond...though they are coming 
into better agreement with the general idea of pushing the mean ridge 
position eastward into The Rockies. This would open the door for more 
unsettled weather beginning with the cold front Tuesday and 
continuing for the remainder of the week as a longwave upper trough 
Parks over the Pacific northwest. There remains great variation between 
operational models and their ensemble members as to when individual 
disturbances would bring chances for rain. Increased probability of precipitation a bit 
considering the persistent longwave trough...but held them near climatology 
due to the timing uncertainty. Temperatures should cool back down to within 
a few degrees of normal midweek...perhaps trending back below normal 
toward the end of the week. Weagle 


&& 


Aviation...a showery pattern to continue through this afternoon 
as a cold upper level trough gradually moves inland. Expect 
primarily VFR conditions to persist...with periodic brief MVFR 
ceilings during heavier showers. There is also a chance for isolated 
thunderstorms and small hail...but confidence in location and 
timing is not high enough to include in tafs. As the trough pushes 
further east and high pressure builds in behind...showers will begin 
to taper off along the coast in the middle afternoon and over the 
interior during the late afternoon and early evening. High pressure 
strengthens overnight Sat into Sun morning...possibly allowing patchy 
fog may to develop toward 12z sun. 


Kpdx and approaches...showers chances continue through this 
afternoon. Expect mainly VFR with brief periods of MVFR during 
heavier showers. There is a threat for thunderstorms at the 
terminal or in the vicinity between 18z Sat and 00z sun. Pyle 


&& 


Marine...seas have remained a little higher than the enp guidance 
was suggesting for this morning. They are currently sitting at 8 
to 10 feet. Expect them to gradually subside through the 
day...eventually reaching 5 feet tonight or early Sun morning. 


Fairly benign conditions are expected today and tonight as high 
pressure moves over the waters and then pushes inland. A warm front 
is then expected to move into the waters Sun morning...then lift 
northward through the day. The latest model runs have trended a 
little stronger with the winds...indicating that a period of Small 
Craft Advisory southerly winds are likely on sun especially over 
the outer waters. Seas should also increase a bit in response to 
the winds...but are currently expected to remain below 10 feet. 


Another break is expected on Monday before the next front arrives Monday 
night or Tuesday. This front does not currently look all that 
impressive in the forecast models...but another round of low end Small 
Craft Advisory winds is currently being advertised. Forecast 
confidence decreases for the latter half of next week...but no 
major weather systems are currently expected. Pyle
