.SYNOPSIS...High pressure lingers through Tuesday with an upper
level low near northern California. Temperatures will be in the
upper 80s to low 90s through Tuesday, but will quickly cool on
Wednesday as the California low moves inland. Slight chance for
showers on Wednesday in southwest Washington. Warmer
temperatures return for the latter part of the week and into the
weekend as a weak upper level ridging is expected to return.
&&
.SHORT TERM...Tonight through Wednesday Night...High pressure
continues to linger over the northeast Pacific which will keep
conditions dry and warm through Tuesday. Today and Tuesday will
be very similar as the overall pattern is not expected to change
significantly until late Tuesday/early Wednesday. Daytime highs
tomorrow are expected to be in the upper 80s to low 90s, upper
60s to low 70s along the coast and mid 70s to mid 80s for the
Cascades. Overall, expect daytime highs tomorrow to be just a
tad cooler than today. There remains a Moderate HeatRisk for
the inland valleys including the Gorge and valleys within the
Cascade Foothills through Tuesday.
As Wednesday approaches, a pattern change is expected. Models
have the California low starting to trek eastward running just
south of the OR/CA border as it pushes towards eastern
Oregon/Idaho. As this low moves eastward, the ridge also will
get pushed eastward and a upper level trough starts to dive down
from the eastern Pacific. This will bring much cooler and
moister conditions. Daytime highs on Wednesday are expected to
be in the upper 70s to low 80s inland, upper 50s to mid 60s
along the coast and upper 60s to mid 70s in the Cascades.
This trough also brings around a 20-40% chance of light showers
to southwest Washington with most of northwest Oregon evading
the rain. /42
.LONG TERM...Thursday through Sunday...As the latter part of the
week and weekend approaches, models are starting to come into
agreement that a warming and drying trend is expected to
return. Now, while the exact pattern is still in flux, the
results will be fairly similar. Expect a gradual warm up
starting Thursday with Friday looking to be the warmest in this
four day stretch and Saturday and Sunday looking very similar.
Overall, no precipitation is expected through the long term
period, but daytime highs will slowly warm up through the latter
part of the week and into the weekend. /42
&&
.AVIATION...Clear skies will maintain VFR flight conditions for
all inland terminals through 00z Wednesday. Although the coast
has cleared out this afternoon, there is a 80-90% chance for LIFR
cigs below 500 ft to redevelop around 07z Tuesday as a low marine
stratus deck over the coastal waters pushes inland a bit. Low
stratus may return to KONP sooner than 07z, as the stratus deck
is only a mile or so to the west of the terminal. Surface
visibilities are also likely to lower to 4-5 SM or less once the
marine stratus deck pushes inland.
For winds, expect a typical diurnal summer pattern with breezy
north to northwest winds during the afternoon and evening hours
today. Expect gusts up to 20-25 kt at the coast and up to 15-20 kt
inland, strongest at KONP, KEUG, and KPDX. Winds will weaken
significantly after 04-06z Tuesday as daytime heating wanes.
PDX AND APPROACHES...Clear skies will maintain VFR flight
conditions through 00z Wednesday. Breezy northwest winds with
gusts up to 15-20 kt are expected between 21z Monday and 05z
Tuesday. -TK
&&
.MARINE...Very little change to the forecast with today`s update.
A typical summertime pattern persists through much of the coming
week as surface high pressure offshore maintains north to
northwest winds across the coastal waters. Relatively strong
pressure gradient at the coast due to diurnal heating, and
elevated winds remain in place for all coastal waters through
Monday night. Small Craft Advisories remain in effect through
Monday evening as wind gusts increase a bit more to 25 to 30 kt
Monday. Expect the strongest gusts south of Cape Falcon, while
conditions will be more marginal to the north across the mouth of
the Columbia River and the south Washington coastal waters. Seas
will remain in the 4-6 ft range, comprised mainly of short period
wind-driven waves and a modest, mid-period westerly swell.
