506 am pdt Sat apr 21 2018

Synopsis A cold front is spreading light rain and cascade snow
this morning, mainly north of salem. Showers will end by the early
afternoon with partial clearing this evening. Sunday will be dry and
slightly warmer. Dry weather continues through at least mid next week
with temperatures likely warming into the 80s Tuesday and Wednesday.

Update The cold front is already over the cascades early this
morning, and did a quick update to reduce pops for this morning.

Most of the rain will end before sunrise this morning. Isolated
showers are possible this morning, but do not expect much
measurable rain from the showers. ~tj

Previous short term (from 250 am) Today through Tuesday... A weak
front is moving across extreme NW oregon and SW washington early
this morning. Rain has been light and has been mainly across sw
washington and along the north oregon coast and coastal mountains.

Areas south of salem may not see much if any rain with this front.

The front is quick moving, and should be east of the cascades before
noon. Snow levels are around 4500 to 5000 feet this morning, and
will lower to around 3500 feet late this morning as the rain turns
to showers. Cool and mostly cloudy conditions with onshore flow are
expected this afternoon.

Surface high pressure builds tonight with dry north flow dominating
through Sunday. Temperatures will warm back into the mid 60s Sunday
afternoon with plenty of sunshine across the region despite an upper
level trough moving over the area.

A sharp upper ridge moves over the pacific NW Sunday night through
Tuesday, continuing dry weather. A thermal trough develops along the
coast Sunday night and persists through Tuesday for offshore flow and
warming.Inland temperatures should reach the 70s Monday afternoon,
then the 80s on Tuesday, with the coastal temperatures not much
cooler. ~tj

Long term No changes. Previous discussion follows... Tuesday night
through Friday... Models continue their agreement in showing continued
high pressure and dry, warm conditions through much of next week.

Have warmed the forecast further Wednesday and Thursday, reflecting
guidance trends.

Models have even come into general agreement on the track of an upper
low which moves south off the west coast through midweek. This low
looks likely to be the source of the next rain chances in the long
term period as it tracks back north late in the week and sweeps a
trough across western oregon starting Friday. As it passes, it's
likely to force some shower development, with both the GFS and ecmwf
indicating precipitation accumulation starting Friday. Have kept
slight chance pops Friday, although will need to up them if model
solution remain consistent in the coming days. With the upper low
tracking from the south, the environment should be warm with snow
levels well above the cascade passes, i.E. Rain for the cascades.

Bowen

Aviation 12z TAF package: cold front moved east of kast around
08z and should reach konp by 12z. Radar loop shows front falling
apart as it moves inland. Brief MVFR CIGS may occur as the
weakened front moves across the interior between 11z-15z. However
do not think the probability is high enough to include in TAF at
this time. Northerly flow develops after 18z and then may take a
weak offshore component. Should see mainly high clouds thereafter
but with a little bit of fair weather CU building over the
higher terrain through 22 03z. Northerly flow continues into
sun withVFR conditions.

Kpdx and approaches... Front should move across the area around
12z. Brief MVFR CIGS around 2500-3000 ft possible through 14z.

For now will not include lower conditions in the TAF package.

ExpectVFR conds thereafter. Mh

Marine A front moved ashore overnight with high pressure
quickly building in behind the front. Expect the strongest winds
across the northern waters this morning where a small craft
advisory is in effect. Seas will be near 10 ft today and will
subside below 8 ft by this evening.

Thermal low pressure over northern california will build
northward along the oregon coast over the weekend. This will
allow a summer-like northerly wind pattern to develop. The
southern waters will likely have gusts to 25 kt late this
afternoon through tonight, but the nearshore waters will ease
late this evening.

Winds may turn offshore for a day or two early next week with
gusty winds of 20 to 25 kt possible across the waters adjacent
to the coastal gaps. Surface high pressure looks to return to
the northeast pacific towards the middle of next week, which
should result in winds turning lighter with seas remaining under
10 ft. Mh
