NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
840 PM PST Friday Feb 27 2015 


Synopsis...showers will continue through this evening an upper level 
trough pushes southward across Oregon...then taper off from north to 
south tonight. Snow levels are near the Cascade passes... and a few 
more inches are possible in the Lane County Cascades before snow 
showers taper off later tonight. High pressure and increasing 
offshore flow should yield a mostly sunny and dry weekend with chilly 
nights and mild days. The next upper level through forecast to dig 
down the British Columbia coast will bring another shot of relatively 
cool air and possibly more valley rain and mountain snow showers 
Sunday night and Monday. Strong high pressure will then build back 
for drier weather for much of next week. 


&& 


Short term...water vapor pictures suggested the upper low was 
slowly moving S over western Oregon...probably in the vicinity of 
Linn County. Radar echoes...while still scattered across much of 
oreogn and western Washington...have shown some decrease in coverage and 
intensity in the past few hours over northwest Oregon and western Washington. As 
the low continues S overnight and with drying kicking in with a 
return to a more northerly low level flow expect to see showers 
decrease overnight from north to S. Snowfall rates at the snowtel sites 
in the Cascades this afternoon and evening have been rather 
modest...on the order of 1 to 2 inches per 6 hours...and generally 
limited to 5k feet and above. As such...will keep probability of precipitation high across the 
S part of the forecast area for the rest of the night...but drop the 
advisory for snow in Lane County. 


Remainder of short term discussion unchanged... 
models show good agreement that any lingering showers will taper off 
quickly Saturday morning as our upper trough moves into northern California 
and flow turns offshore. High pressure will build into Washington 
Saturday...with the resulting dry north-NE flow clearing US out quickly. 
By midday expect plenty of sunshine for most of the district but with 
some blustery northerly flow and temperatures stuck in the lower 50s. The 
north-NE flow and dry air mass may make it difficult for any night and 
morning fog to form this weekend except in the most sheltered 
valleys. Not much change expected for Sunday...except perhaps less 
wind away from The Gorge and a few more high clouds in advance of our 
next disturbance. 


Northwest flow aloft will guide the next disturbance into the Pacific northwest 
Sun night/early Monday. Models continue to struggle a bit with the finer 
details...but the broad consensus keeps two distinct systems during 
this event. One will dig southeast along The Spine of The Rockies... 
followed the next surge of cold air to push into the northern plains 
states. The second disturbance remains weaker and tracks down the British Columbia 
coast. 12z/18z GFS/NAM/ECMWF all have enough overwater trajectory for 
at least some showers Sun night/Mon...while the 12z Gem keeps our 
system too weak to produce much in the way of shower activity. Held 
probability of precipitation generally in the chance category late Sun night/early Monday. If we 
do get precipitation...the Cascades could get another dusting of snow but it 
probably will not be much. Weagle 


Long term...no changes. Previous discussion follows. Tuesday 
through Friday...the mean upper ridge position returns to where it 
has been much of this winter Tue/Wed...over the NE Pacific. 
Therefore expect at least a couple days of dry weather 
Tue/Wed...probably longer. It appears the bulk of the cold air 
behind the Sun night/Monday system will stay east of The Rockies...with 
only a small piece of it pushing into the middle-Columbia Basin. Thus 
expect near normal temperatures and dry weather through 
midweek...clear and chilly nights with sunny days and afternoon 
temperatures in the 50s for The Lowlands. Offshore flow should limit fog 
formation. Held probability of precipitation below climatology toward the end of the week as 
models continue to show the mean ridge position anchored near the 
West Coast. Weagle 


&& 


Aviation...a low pressure moving southward along the Oregon coast 
will result in increasing offshore flow and flight conditions 
trending towards predominantly VFR tonight where they will persist 
through 06z Sunday. However...moisture will linger longest at 
konp...keug and ksle so MVFR conditions and possibly even LIFR/IFR 
conditions may develop temporarily in the short term and possibly 
last through approximately 15z Saturday. 10 to 20 knots north to east 
winds Saturday afternoon will ensure all locations turn VFR. 


Kpdx and approaches...increasing offshore flow and drier air will 
bring VFR conditions to the taf site through 06z Sunday. /Neuman 


&& 


Marine...a low pressure will slowly drop southward along the coast 
tonight and Saturday. This will result in gusty northeasterly winds 
spreading from north to south across the waters tonight. At this 
point...it appears gusts of 25 knots will be most likely across the 
outer waters...but there is a chance the inner waters could 
experience these higher gusts Saturday. Opted to leave them out of 
the Small Craft Advisory for now...but they may need to be 
added...particularly the central Oregon coast inner waters. 


Expect winds to relax Saturday evening and Sunday before increasing 
again across the outer waters Sunday evening and Sunday night as 
pressure gradients temporarily increase again. Another Small Craft 
Advisory for winds may be necessary. Otherwise...high pressure looks 
to become increasingly dominant over the northeast Pacific next 
week...resulting in relatively benign winds and seas. /Neuman 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds until 3 PM PST Saturday for 
waters from Cape Shoalwater Washington to Cascade Head or from 10 to 
60 nm. 


Small Craft Advisory for winds until 9 PM PST Saturday for 
waters from Cascade Head to Florence or from 10 to 60 nm.
