Heavy showers will result in reduced visibility and ponding of water on roadways during the commute until about 650 am. Locations impacted include...Hillsboro...Portland...Vancouver willsonville..Aurora Gresham...Sunnyside If driving you should slow down and allow extra time. Heavy rain may cause water to pond and accumulate on roadways and in low spots...and cause slippery conditions for drivers and pedestrians. This includes the following highways in Washington...

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
355 am PDT Thursday Apr 24 2014 


Synopsis...a cold front will move inland this morning with rain 
followed by showers. The snow level will lower today but showers will 
be lighter. The upper low will move south and cold air will move over 
the area tonight and Friday for continued showers. There will be a 
slight chance of thunderstorms Friday afternoon and evening as a 
result. There should be a brief break in the wet weather Saturday. 
Another significant frontal system is expected late Saturday on the 
coast with rain spreading inland Saturday night. 


&& 


Short term...cold front near the north Oregon coast at 3am will 
push inland during the morning with rain turning to showers. Quite a 
bit of rain has fallen overnight in the mountains with locations in 
the north Coast Range and the South Washington Cascades in the 1.5 
to 2.5 inch range. Rivers draining the Coast Range and the South 
Washington Cascades have responded with some rapid rises. I expect 
the Cowlitz river to rise above bankfull at Kelso this morning but 
should remain below flood stage. The Grays River in Pacific County 
will rise above bankfull and could approach flood stage this 
morning. However...the cold front is almost there at 345 am and 
precipitation will taper off by 5 am with allowing for a recession 
around 8 am just below flood stage. 


Showers will become less frequent middle day today. I am going to 
cancel the Snow Advisory for the Cascades as the snow level is 
around 5500 to 6500 feet and above the passes. Timberline and higher 
ski areas are the only places likely to get much snow this morning. 
Then the snow level will drop as the cold air moves in this 
afternoon and evening. As the flow becomes more westerly some snow 
will fall in the Cascades and at the highest passes but amounts will 
not warrant an advisory. Snow level will continue to lower tomorrow 
dropping below the passes later tonight and tomorrow. Middle level 
southwest winds will decrease tonight and tomorrow so snow amounts 
at the passes will be light. 


There is probably not enough surface heating today or enough cold 
air aloft to result in thunderstorms...although some small hail is 
not out of the question. However...by Friday afternoon the NAM and 
GFS both indicate the cold pool is over northern Washington and 
extends south with cooler air aloft extending into northwest Oregon. Air 
mass is unstable enough to warrant a slight chance of thunderstorms 
over the inland areas Friday afternoon and evening. 


The upper trough moves east of the area Friday night and the showers 
should taper off dramatically after sunset. I think we should have a 
break in precipitation for most of Saturday...except along the coast 
where light rain may spread in by afternoon. Rain will spread inland 
from the next warm front Saturday night. Model timing is pretty 
consistent. Schneider 


Long term...no changes. Previous discussion follows...Saturday night 
through Wednesday...the latest medium range forecast models continue to 
advertise a frontal system moving onshore Sat night and early sun. 
Kept categorical probability of precipitation for this time period...with a transition to 
showers later in the day Sunday behind the trailing cold front. A 
weak warm front may brush the forecast area with some light precipitation 
on Monday...but the trend will be toward drier weather as upper level 
ridging builds over the Pacific northwest. Right now...confidence is pretty high 
that Tuesday will be warm and dry with the ridge directly overhead...and 
high temperatures were raised significantly with the latest forecast package. 
Model uncertainty begins to increase Wednesday...as the 12z GFS and some of 
its ensembles indicate that a trough over the NE Pacific will split...with 
the northern energy pushing into the Pacific northwest Wednesday as an open trough. The 
12z European model (ecmwf) maintains a NE Pacific closed low that hardly moves through 
the end of the week...allowing ridging to remain in place over the 
Pacific northwest for several days. Have kept some low chance probability of precipitation on Wednesday due 
to this uncertainty. Pyle && 


Aviation...cold front will push onshore soon...then push inland 
to the Cascades by 13z-15z. IFR and MVFR at the coast ahead of the 
front with a mix of VFR and MVFR inland with main precipitation shield 
along and ahead of the front. Gusty S-south-southwest winds ease some and 
become SW. 


Behind this front the air mass will become more convective in 
nature. Steady rain will switch to showers behind the front with 
improved visibilities outside of showers. Showers will persist through 
the day today...along with a few breaks in the clouds. Heavier 
showers may produce small hail in the afternoon. 


Kpdx and approaches...VFR with occasional MVFR ceilings/visible this 
morning ahead of a cold front. Winds will remain gusty at 
times... up to 25 knots with passage of the cold front around 13-14z. 
After that winds turn west-SW with improving ceilings/visibilities but 
continued showers. Expect general VFR with showers today...though 
periods of MVFR are likely at times. Weagle/kmd 


&& 


Marine...low pressure off Vancouver Island will push into 
British Columbia today and weaken. This low will send a cold front 
onshore around or slightly before sunrise...bringing gale force 
gusts to the inner waters. Conditions have eased farther offshore 
and dropped the gale there. 


As the low tracks inland...blustery west-SW flow will dominate 
Thursday...though winds will be gradually easing throughout the 
day. There may be a gust to 35 knots in the far northern outer 
waters...most guidance suggest sub-gales will dominate today. Very 
choppy combined seas 11-14 feet likely through Thursday morning...but 
this should slowly subside later Thursday/Thursday night. Lighter conditions 
expected Friday/early Sat as the low pressure system fills over 
British Columbia and pressure gradients slacken over the 
area...though showers may bring squally wind gusts on Friday. 


Another organized front will bring the potential for gales again 
later Sat. Kmd 


&& 


Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds until 8 PM PDT this evening for 
waters from Cape Shoalwater Washington to Cascade Head or from 10 
to 60 nm-waters from Cascade Head to Florence or from 10 to 
60 nm. 


Small Craft Advisory for hazardous seas until 11 am PDT Friday 
for waters from Cape Shoalwater Washington to Cascade Head or from 
10 to 60 nm-waters from Cascade Head to Florence or from 10

Gale Warning until 8 am PDT this morning for coastal waters from 


Cape Shoalwater Washington to Cascade Head or out 10 nm-coastal 
waters from Cascade Head to Florence or out 10 nm.
