NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland 
902 am PDT Monday Mar 30 2015 


Synopsis...mild and mostly dry weather will continue during the 
daytime today a flat upper level ridge remains over the Pacific northwest. A 
cold front will push across the region tonight ushering in a much 
cooler and more seasonable air mass along with showers and lower 
snow levels that will last through the end of the week. 


&& 


Short term...radar and surface observations indicate any rain along 
the S Washington coast had ended this morning as the overall upper pattern 
has begun to amplify with the inland ridge building and the trough 
offshore digging. Some low level moisture has resulted in patchy fog 
and stratus in the inland valleys...and a fairly solid area of 
stratus along the coast this morning. Low level flow was a light 
offshore flow this morning suggesting inland clouds should burn off 
this morning...while along the coast there may be a temporary break 
up of the clouds before a stronger onshore flow late today fills the 
clouds back in at the end of the day. Forecast area remained in a 
mild air mass with 800 mb temperatures at sle at 12z around 4c. Inland clouds 
may provide a slow start to temperatures rising early today but likely will 
still see sufficient sun this afternoon to bring temperatures close to 
yesterdays highs. Along the coast the morning stratus and afternoon 
onshore winds are likely to limit temperatures to 55 to 60 range. 


Remainder of short term discussion unchanged...models continue to 
trend later with the arrival of a cold front tonight...so have 
trended the same with probability of precipitation and winds. Now looks like rain will 
arrive at the coast between 03z and 06z Tuesday...spreading inland 
through the overnight hours. Cold front and coincident shortwave 
will usher in cooler air with freezing levels coming down to around 
4000 feet at the coast and in the valley. Still expect showers behind 
the front to have a good chance of producing small hail and will 
keep a slight chance of thunder with instability still looking 
pretty good. 


Another shortwave will keep slight chance for thunder again Wednesday. 
Expanded slight chance area east to include the coast and Pacific 
waters with models showing fairly widespread instability during the 
afternoon hours. Snow levels will drop to 3000 to 4000 feet Tuesday and 
Wednesday...so a few inches of snow are possible at the Cascade 
passes. 


Long term...no changes. Previous discussion follows. The cold upper 
trough of midweek is depicted by models exiting the region 
Thursday...with a weak ridge moving across late Thursday and Friday. GFS and 
European model (ecmwf) both indicate some light residual precipitation Thursday...but with 
upper dynamics shifted east and mainly just some shallow low level 
moisture left will cut back on probability of precipitation a bit for Thursday. 12z model runs 
also a bit slower in digging in the next trough and cold front late 
Friday so will back off on probability of precipitation across the S part of the forecast area 
Friday. Over the weekend models now tending to dig the next trough down 
off the coast...close enough to push a front through Sat and keep 
the region in a cool unstable air mass for sun. 


&& 


Aviation...MVFR ceilings along the coast should persist through midday 
today as coastal stratus stays in place over coastal taf sites. This 
should lift to VFR this evening as southerly winds pick up along the 
coast ahead of the front which will move through late tonight. 
Models suggest MVFR ceilings return at coastal taf sites late tonight 
behind the front with light rain possibly reducing visible as well. This 
seems plausible with onshore flow behind the front. 


At inland sites...VFR conditions prevail and should continue this 
morning into this afternoon. As front moves onshore...expect winds 
to ramp up a bit out of the south this afternoon/evening with 
increasing middle-level clouds around fl060. As the front moves off to 
the east tonight...models suggest ceilings dropping to MVFR at inland 
sites after 07z Tuesday. May hint at this in the tafs...but with the 
type of front moving through inland sites may see continued VFR due 
to mixing behind the front. 


Kpdx and approaches...VFR conditions continue through today. 
Increasing middle-level clouds this evening around 05z ahead of the 
front. Ceilings could drop to MVFR around 07-08z tonight...but 
confidence is low at this time. -McCoy 


&& 


Marine...southerly winds expected to increase this morning over the 
northern outer waters...spreading to the southern outer waters and 
inner waters this afternoon. This is in response to a front moving 
through the waters this afternoon/evening. Winds will peak just 
ahead of the front around 20 to 25 kts gusting to 30 kts before 
dropping back down below small craft criteria by around midnight 
tonight. Models have slowed the approach of this front...which has 
pushed back the arrival of peak winds a bit. Now peak winds for the 
outer waters are expected to occur late this afternoon...and for the 
inner Waters Peak winds should occur during the middle-evening hours. 


Seas currently around 10 feet should stay around 10 feet in the outer 
waters through midday today...while seas in the inner waters should 
drop to around 9 feet this morning. Seas expected to build back up 
above 10 feet in the inner waters as winds increase this afternoon 
ahead of the front. Seas expected to build to 11 to 13 feet this 
afternoon/evening as the front moves through...and stay above 10 feet 
through the day Tuesday. 


An active weather pattern continues through this week with another 
front expected to move through Wednesday night. As of now...this 
system does not look very strong...with maybe a chance of small 
craft gusts behind this front. Otherwise...seas after Tuesday should 
stay below 10 feet through Friday. -McCoy

Pqr watches/warnings/advisories... 
or...none. 
Washington...none. 
Pz...Small Craft Advisory for winds until 11 PM PDT this 
evening for coastal waters from Cape Shoalwater Washington to Cascade 
Head or out 60 nm. 


Small Craft Advisory for hazardous seas until 5 PM PDT Tuesday 
for coastal waters from Cape Shoalwater Washington to Florence or out 60 
nm. 


Small Craft Advisory for winds from 2 PM this afternoon to 11 
PM PDT this evening for coastal waters from Cascade Head or to 
Florence or out 60 nm. 


Small Craft Advisory for rough Columbia River bar from noon 
today to 5 PM PDT this afternoon. 


Small Craft Advisory for rough Columbia River bar from 1 am to 
6 am PDT Tuesday. 
Aviation...a radiationally cooled marine stratus layer formed 
over the northern Willamette Valley this morning and is appearing 
in some form at all taf sites except for kttd. Pilot reports 
indicate it is about 800 feet thick with tops 011 to 014 above ground level. A 
very weak offshore flow is keeping it mostly confined from the 
Willamette river and west through the valley. Keug is on the fringe 
of the deck and they may get enough sunshine this morning to mix 
the clouds up before they get too thick. Otherwise...local single 
column model indicates a breakup around 18z but given the fact 
the stratus does not cover the entire valley...will nudge an hour 
earlier due to sun sneaking underneath from the east. 


MVFR ceilings will continue today under that marine stratus influence 
but begin to lift some towards afternoon when prefrontal winds and 
instability reach the coast. 


Cold front reaches the coast around 04z and crosses I-5 around 
06z with a few hour period of embedded moderate rain and brief 
wind gusts 20 to 25 knots at all locations. Then expect a MVFR deck 
around 025 mean sea level to develop and remain through 31/18z under 
trailing showers. 


Kpdx and approaches...IFR stratus deck will remain through 17z. 
Prefrontal ceilings around 040 develop near 03z and then fall to 
around 020 with and after the frontal crossing near 06z. Expect a 
brief burst of 20 to 25 knots wind gusts with the frontal passing. 
MVFR ceilings then remain in place through the morning push. /Jbonk 


&& 


Marine...cold front slightly delayed again and a bit weaker with 
the morning model runs but not significantly enough to alter the 
timing of the Small Craft Advisory for winds. Will see peak winds 
with gusts 25-28 knots reach the outer waters as the front crosses 5 
to 7 PM and for the inner waters 6 to 9 PM. Seas have remained 
around the 10 feet height and may briefly drop below criteria to 9 
feet but do not feel there will be a significant time to justify 
breaking up the Small Craft Advisory for seas given another 
westerly swell will return plus increasing wind waves will loft 
them back above 10 feet late this afternoon and early this evening 
with the frontal crossing. Seas will briefly hit 12-13 feet during 
the maximum winds then ease back to around 10 feet through Tuesday. 


An active weather pattern continues through this week with another 
front expected to move through Wednesday night. As of now...this 
system does not look very strong...with maybe a chance of small 
craft gusts behind this front. Otherwise...seas after Tuesday 
should stay below 10 feet through Friday. Jbonk/McCoy
