.SYNOPSIS...Dry conditions will persist through Friday aside
from a 15-30% chance of showers over the Oregon Cascades in Lane
and Linn counties Wednesday afternoon through Thursday evening
and Friday afternoon/evening. High pressure will maintain well
above normal temperatures for this time of year through Monday.
Onshore flow returns Tuesday and Wednesday, bringing relatively
cooler temperatures. Trending a bit warmer again Thursday into
Friday with light offshore flow developing.

&&

.DISCUSSION...Sunday through Saturday night...High pressure and
low-level offshore flow remains in place today with scattered
to broken high clouds and light winds, aside from the western
Columbia River Gorge and the Troutdale, Washougal and Camas area
where easterly winds are a bit breezy with gusts up to 15-25
mph. Expect easterly winds to ease late in the day as low-level
offshore flow weakens. Despite the aforementioned high clouds in
place today, temperatures are still on track to warm well into
the mid to upper 70s across the interior lowlands and upper 60s
to lower 70s at the coast. Most locations within the Willamette
Valley and greater Portland/Vancouver metro have anywhere from a
10-30% chance of reaching 80 degrees or warmer this afternoon,
which would likely only occur if high clouds are thin enough
during peak heating. Although high pressure weakens a bit
tomorrow with 850 mb temperatures cooling slightly, high clouds
will be dissipating. Given a full day of sun, Monday is on track
to be just as warm as Sunday with similar probabilities of
reaching 80 degrees. The only exception is at the coast where
the return of onshore flow will bring relatively cooler
temperatures compared to Sunday with highs near 60 degrees. A
few record high temperatures may be tied or broken both Sunday
and Monday. It is not recommended to cool off in local lakes and
rivers as water temperatures are currently frigid enough to
result in cold water shock, which can become life threatening.

Models and their ensembles continue to suggest temperatures will
trend cooler Tuesday and Wednesday with dry northwest flow aloft and
relatively stronger low-level onshore flow. The NBM depicts low model
spread for temperatures both days, suggesting highs will likely wind
up in the low to mid 60s, except 55-60 degrees at the coast. Note dry
weather will persist both days, with one potential exception over the
Oregon Cascades in Lane and Linn counties beginning Wednesday
afternoon and continuing through Thursday evening. This is when there
is a 15-30% chance of light showers due to wrap-around moisture from
the south associated with an upper level low off the California
coast. It is also worth mentioning that areas of morning frost are
still possible on Wednesday and Thursday, mainly away from the
Portland metro where morning lows will be coolest. That said,
probabilities for lows of 36 degrees or colder have decreased
slightly from previous cycles of the NBM. Probabilities now range
between 10-25% over the interior lowlands and inland coastal
communities, except 1-5% in the Portland metro to the east of the
West Hills and 40-75% in the Upper Hood River Valley from Odell to
Parkdale. Anyone with sensitive outdoor vegetation that is
susceptible to frost damage should stay up-to-date on the temperature
forecast over the coming days and monitor for potential Frost
Advisories.

Model guidance is now trending warmer Thursday afternoon through
Friday compared to previous cycles due to potential shortwave ridging
on the northeast periphery of the aforementioned upper low. As such,
the deterministic NBM is now suggesting highs in the upper 60s to
around 70 degrees over the interior lowlands both days. However,
there is still some uncertainty regarding how amplified the
shortwave ridge will become, and there is a 25% chance highs wind up
in the mid 60s or cooler. Chances for rain finally return next
weekend (25-50% chance), however guidance suggests rain amounts will
most likely be light and non-impactful (80-90% chance total rain
amounts will be under 0.25 inches from 5am Saturday through 5am
Sunday, April 11-12).

.AVIATION...Widespread VFR flight conditions will continue across
the majority of northwest OR and southwest WA through Sunday
night with scattered to broken high clouds above FL250. Breezy
easterly winds continue at KTTD with gusts up to 25 kt, but should
weaken after 03Z Monday. Otherwise, winds remain light and
variable.

A southerly wind reversal along the coast will bring a surge of
clouds to coastal locations after 06Z Monday. Expect IFR/LIFR
conditions along the coast starting at KONP around 07Z Monday and
at KAST around 10Z Monday. Given the persistent southerly winds
expected, minimal if any improvement along the coast is expected
from 12Z-18Z Monday.

KPDX AND APPROACHES...Expect VFR flight conditions to continue
with scattered to broken high clouds above FL250. Light and
variable winds less than 5 kt should become easterly less than 10
kt sometime around 19Z Sunday. /42

&&

.MARINE...High pressure remains anchored over the waters and is
resulting in rather benign conditions. Seas early Sunday
morning were around 4 to 7 feet and are expected to remain
within that range through at least Thursday morning. Northerly
winds have decreased to below 15-20 kt over the waters early
Sunday morning, bringing an end to Small Craft Advisory
conditions. Winds will turn more offshore and weaken later
Sunday morning before temporarily becoming southerly late Sunday
into Monday morning as a thermal trough along the coast moves
offshore. Winds are still on track to become northwesterly by
Monday afternoon, and will then remain out of the north to
northwest through the remainder of the week.

Seas are expected to build slightly to 7 to 9 ft late in the week
in response to increasing northerly winds (up to 20-25 kt) and a
fresh northwesterly swell that will impact the waters. This will
likely result in another round of marginal Small Craft Advisory
conditions. -23
