.SYNOPSIS...Ridging will gradually shift eastward into early
next week, supporting hot and dry conditions. The hottest days
of the year so far are expected as inland valley areas are
likely to surpass 90 degrees both Sunday and Monday, while the
coast stays cooler. Prolonged exposure to the hot temps could
result in heat related illnesses. A breakdown of the ridge and
may see a return to more seasonable temperatures later next
week.

.SHORT TERM...Now through Monday Night...A ridge of high
pressure over the northeast Pacific will gradually shift
eastward this weekend and into early next week. Low to mid 80s
are expected this afternoon throughout the Willamette Valley and
Columbia River Gorge. Temps will continue to rise Saturday and
Sunday, with the warmest temps of the year so far expected
across southwest WA and northwest WA. The center of the ridge
will continue eastward with the center almost directly overhead
on Sunday. Thermal low pressure is expected to develop west of
the Cascades both days as well, helping support at minimum, weak
easterly downslope flow. Saturday highs are expected to reach
into the upper 80s, possibly low 90s while the coast remains in
the upper 60s to low 70s. Sunday will be even warmer with inland
temps likely surpassing 90, possibly 95 degrees. Probs to reach
90 degrees are 80 to nearly 100% and 40- 70% to reach 95 around
the metro, slightly lower around 20% for the rest of the
Willamette Valley.

This warm-up will support a Moderate HeatRisk across more
densely populated areas throughout the inland valleys on
Saturday, namely along the Willamette and Lower Columbia Valleys
from Salem north through Kelso/Longview including Portland as
well as the Lower Hood River Valley. Moderate HeatRisk expands
on Sunday to much of the Cascade foothills and portions of the
Coast Range while portions of the western Columbia River Gorge
and eastern metro could bump up to Major HeatRisk. The Moderate
HeatRisk pulls back a bit on Monday but hot temps, similar to
Sunday, are expected for much of the Willamette Valley and
Columbia River Gorge. The hotter than average temperatures
throughout the Willamette Valley and Columbia River Gorge have
prompted the issuance of a Heat Advisory that will be in affect
from 10 am Sunday through 10 pm Monday. Tips on how to remain
safe during this warm-up can be found in our Heat Advisory
product.

Overnight lows will stay in the 50s for most locations, but
Saturday and Sunday nights could remain in the low 60s,
particularly in urban areas. This will help give some reprieve
from the hot conditions during the day. While not extreme, the
prolonged heat may still pose health risks to sensitive
populations. Coastal areas will remain cooler with highs mostly
in the low to mid 70s, though some locations could briefly reach
the upper 70s depending on wind direction. Breezy afternoon
winds are expected daily, occasionally gusting to 15-20 mph in
the valleys. These winds could provide modest, localized relief
from the heat but will not significantly affect overall warming.

.LONG TERM...Tuesday through Friday...By Tuesday into the
middle of next week, the ridge will break down as large-scale
troughing becomes favored over the West Coast. While the details
remain low-confidence, a return to more seasonable temperatures
in the 60s and 70s is favored by the latter half of the week.
Embedded shortwaves passing over the Pacific Northwest may bring
some low chances for precipitation, but at this lead time, only
a few global ensemble members are suggesting any accumulating
rainfall. -Picard

.AVIATION...Minimal impacts to the aviation forecast as high
pressure lingers over the region. Clouds are sitting just offshore
which continually surge inland, then push out. Therefore have seen
variable CIG conditions around KONP and KAST. Because of this,
maintaining a slightly lower category to prepare for the lower end
conditions. Otherwise, VFR elsewhere. Diurnal winds have kicked in
with northerly wind gusts around 25 kt along the coast, and 20 kt
inland. Highest winds will be within the Willamette Valley. After
04Z Saturday, skies will fill in and winds will ease. An inversion
layer will set up around 1000-2000 ft AGL, but not expected to be
impactful.

PDX AND APPROACHES...VFR with no concerns through the forecast
period. Diurnal northwesterly winds with periodic gusts up to 20
kt (30% chance between 00Z-6Z Saturday). However, they will not be
consistent. Winds ease overnight and VFR clouds fill in.

.MARINE...High pressure with a thermal through setting up along
the coast. Northerly winds intensify, especially along the inner
coastal waters with gusts exceeding 25 kt. Will see these
conditions persist a bit longer than previously forecast so have
extended the Small Craft Advisory until early Saturday morning. A
combination of winds and seas are sparking that advisory as seas
are around 6-8 ft at 10 seconds. Through the weekend, the thermal
trough will intensify, but the pressure component will not
necessarily be there. With the incoming building of the ridge,
expect typical summer time northerly winds. Could see some
breezier winds through the bays and some exposed moorages, but
overall, gusts should remain below 20 kt.

Onshore flow returns Tuesday into Wednesday as the ridge breaks
down. Winds will become gusty once again, but not expecting winds
above Small Craft Advisory criteria. -Muessle
