Severe Weather Alert Descriptions

 Special Statement  Statement as of 2:34 PM PDT on September 23, 2014


... The first organized storm system of the season for northwest
Oregon and southwest Washington arrives overnight...

An early Fall storm system will bring a drastic change in the weather
overnight and Wednesday. The main weather impact will be widespread
moderate to heavy rain that will spread inland from the coast
tonight... and into the Cascades by Wednesday.

Rainfall totals by the end of the day Wednesday are expected to be
mainly between a half an inch to one and a half inches... with up
to two inches in the mountains. This may result in some ponding
of water in low lying areas.

Motorists are urged to use caution on the roadways. Given the
long period of dry weather that has preceded this front... residual
oil and grease on the Road surfaces can become quite slick at the
onset of the rain.

Gusty winds are expected along the coastal beaches and headlands
tonight... with gusts up to 50 mph possible.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
245 PM PDT Tuesday Sep 23 2014 


Synopsis...deep low pressure over the NE Pacific will slowly push a 
front inland tonight. Tropical moisture will accompany the front 
bringing an area of heavy rain as the front moves inland tonight and 
Wednesday. The upper trough will slowly move through later this week and 
into the weekend keeping a chance for showers along with cool 
weather. 
&& 


Short term...water vapor pictures showed a deep upper low over the 
NE Pacific early this afternoon around 45n 138w. Models indicated 
the low was expected to slowly move east over the next couple of days 
before begining to fill and move S Friday. A plume of moisture with 
origins from the tropical west Pacific was entrained into the system. 
GFS estimates close to 1.75 inches of precipitable water was 
expected to reach up to the Oregon coast this afternoon...with 
values on the order of 1.4 inches expected to make it inland 
tonight. This would put precipitable water values on the order of 4 
or more Standard deviations above normal for this time of year...an 
impressive amount. A roughly north to S oriented front is forecast to 
push inland tonight...but progressive will tend to be on the slow 
side due to an increasingly southerly flow aloft. The baroclinic 
zone will provide a focus for rainfall tonight into Wednesday as it makes 
its way into the Cascades by Wednesday afternoon. The southerly flow will 
limit orographic effects...so inland valleys as well as mountains 
and coast stand to see a rather wet 24 hours. Rainfall rates are not 
expected to be high enough to warrant any kind of Flood Watch at 
this time...but burn scars especially will need to be closely 
monitored. Some winds are lieky to accompany the front as it makes 
landfall tonight...but a strong southerly component to the wind 
indicates peak winds are likely to be brief right with the 
front...with gusts up to about 50 miles per hour on headlands and beaches. 


Models suggest that the baroclinic band may be slow to clear the 
Oregon Cascades Wednesday night as the front becomes parallel to the upper 
flow. Will keep probability of precipitation on the high side there through the night. 
Otherwise the region falls under the approaching cool trough Thursday and 
Friday with forecast soundings indicating some instability. As the 
upper torugh begins to dig further S though...dynamics become 
increasingly directed S of the forecast area. Overall then will tend 
towards limiting probability of precipitation to chance category most areas Thursday into Friday. 


Long term...forecast confidence is still quite low for the extended 
period. However...the various model solutions are starting to trend 
towards one another. The European model (ecmwf) has continued to keep showery 
conditions around for much of the weekend while the GFS has begun to 
slow the progression of the upper level low...keeping it in the 
region into Sunday. This will likely keep a chance of showers for 
much of the County Warning Area on Saturday and Sunday. The next disturbance is 
still on track to arrive on our doorsteps late Sunday into early 
Monday. This will likely bring another shot of widespread rain to 
the region on Monday and Tuesday. Upper level ridging is forecasted 
to build into the Gulf of Alaska towards the middle of next week. 
Temperatures in the extended will be slightly below seasonal 
normals. /64 
&& 


Aviation...light rain is starting to pick up and ceilings are 
lowering across the area this afternoon...ahead of the 
approaching warm front. MVFR/IFR conditions will begin to develop 
along the coast through later this afternoon. Expect steadier rain 
to begin moving onshore this evening and overnight...with 
widespread MVFR conditions. Gusty southerly winds are starting to 
be observed at coastal sites...and winds will continue to 
gradually increase along the coast later today into tonight. Wind 
gusts of 30 to 40 kts may be observed at times. The trailing cold 
front will push onshore Wednesday morning...with showers lingering 
into the afternoon. Expect some improvement in flight conditions 
behind the front. 


Kpdx and approaches...light rain beginning to fall around the 
terminal this afternoon as warm front approaches. Expect increase 
in rain and lowering ceilings later this afternoon and especially this 
evening. MVFR conditions likely to develop between 03-06z and 
persist through Wednesday morning. Flight conditions likely to improve 
after passage of cold front around 12z. McCoy/pyle 


&& 


Marine...southerly winds increasing steadily this afternoon ahead 
of strong early-season frontal system. Off-shore buoy reports are 
tracking well with current model forecast wind speeds...increasing 
confidence that gale-force winds will develop over the coastal 
waters later this afternoon. Expect southerly winds of 20 to 
25 knots and widespread gusts of 30 to 35 knots...lasting into early 
Wednesday morning. 


In response to increasing wind...seas have increased to around 8 
feet at current...and will become progressively larger and choppier 
later this afternoon and tonight as the gale force winds start to 
develop significant wind waves. Seas will likely top out at 10 to 
12 feet tonight. The main fetch area of swell will arrive on early 
Wednesday...with west swell building to 15 to 18 feet Wednesday am. The largest 
swell will remain over the outer waters. With winds...this makes 
combined seas at 14 feet near shore and close to 20 feet over the 
outer waters. 


Winds should decrease between 09-12z as the cold front pushes 
onshore. Expect a lull in the winds to last through middle-day before 
increasing again ahead of secondary front associated with the 
occlusion. At this time...the models keep the strongest winds to 
the west and north of our waters...but some borderline gale-force 
gusts are possible over the outer waters tomorrow afternoon. 


Winds and seas will begin to diminish Wednesday night. Expect 
seas to drop into the middle teens overnight and into the low teens 
by Thursday morning. Small-Craft Advisory winds will likely 
continue through at least Thursday...which will in turn keep seas 
near or above 10ft through the end of the week. McCoy/pyle
