.SYNOPSIS...Dry and increasingly sunny conditions are expected for
the first part of the week as a weak upper level ridge builds over
the region. A large upper level low will dig southward from Alaska
to offshore of British Columbia early this week, increasing the
southerly flow. Wednesday will be the warmest day this week, with
highs over much of the interior in the mid to upper 80s. Showers
and isolated thunderstorms will be possible over the Cascades
Wednesday and Thursday afternoon.
&&
.SHORT TERM /TONIGHT THROUGH WEDNESDAY/...The latest forecast
remains on track with no updates this evening. The onshore
gradients will relax quite a bit as an upper level low from Alaska
digs southward tonight into Monday. It will park just offshore of
B.C. much of the week. With the change in pattern, the marine
layer will be primarily confined to the Pacific coastline. As the
ridge gets confined in between the two lows, it will begin to
slowly build over much of the northwest CONUS through the week,
which will increase the southerly flow aloft (the axis of this
ridge will be just east of the Rockies tilted northwesterly).
Temperatures will get back to average Monday, with the warming
trend continuing through to Wednesday. HeatRisk remains minor for
most of the region, although a few pockets of moderate (orange)
HeatRisk are possible in pockets of the interior (Seattle metro
areas away from water, and Cascade Valleys/Foothills). Couple of
these areas could see highs in the upper 80s (went with the 50%
percentile of the NBM given the mean was a bit cooler with the
pattern).
With the increase of southerly flow, the airmass will become more
unstable as early as Wednesday (particularly over the Cascades).
the air will become increasingly unstable over the region. The
most unstable air will setup over the mountains with CAPE values
getting upwards of 300-500 J/kg in the afternoon and evening. A
small perturbation trough appears to move over the Cascades on
Wednesday and Thursday. This provides enough lift over the
mountains to produce a shower and isolated thunder threat for the
Cascades Wednesday afternoon and evening. The threat is very low
over the Olympics with this pattern (at the moment). The primary
concern with storms that develop is lightning (see fire weather
discussion for concerns), and also the possibility of heavy
downpours producing flash flooding over burn scar areas.
Additional details on hazards will be provided provided as hi-res
guidance becomes available.
.LONG TERM /THURSDAY THROUGH SUNDAY/...The same unstable air
pattern is expected to continue into Thursday, with the shower and
isolated thunderstorm threat expanding for all of the Cascades
and foothills. Afterwards on Friday some models have different
solutions of the low moving inland through the weekend. Will
likely have a chance of at least showers on Friday, but unsure if
a front will sneak through the region with a separate shortwave
trough. Nevertheless, conditions will cool slightly through the
weekend with increased cloud coverage.
HPR
&&
.AVIATION...VFR conditions across the region this evening with
mostly clear skies. Lower stratus will likely redevelop late tonight
into Monday morning, but coverage should be less widespread into the
interior than the past mornings. The low stratus is expected to
remain confined primarily along the coast, bringing MVFR and chance
of IFR (20-30%). The latest guidance shows the low stratus may
attempt to move into the Kitsap Peninsula and portions of
southwestern interior, with current probabilities of MVFR at 20%.
KSEA...VFR conditions expected to prevail this evening and
throughout the TAF period. Not expecting the low stratus to impact
the terminal overnight into Monday morning. W/NW surface winds at 3-
4 kt will become more southerly overnight. Winds will become W/NW
again Monday evening at 6-7 kt.
&&
.MARINE...The marine weather pattern remains stable day to day
through the first half of the week with strong high pressure over
the northeastern Pacific maintaining an onshore flow pattern with
northwest winds over the coastal waters and westerly winds through
the Strait of Juan de Fuca. A few occasional gusts of 20-25 kt are
possible both this evening and again late Monday evening in the
central Strait, but these aren`t expected to be frequent or
widespread enough to warrant an advisory. A stronger push is
possible later in the week around Thursday as onshore flow
strengthens. Otherwise, no significant marine weather issues are
expected over the coastal waters with winds and waves remaining
short of any thresholds.

&&
.FIRE WEATHER...No fire weather concerns through Monday. Conditions
will start to warm up and dry out early next week as an upper level
ridge builds over the Pacific Northwest. Concerns begin to increase
Tuesday and Wednesday as a trough slowly drifts south out of the
Gulf of Alaska and the flow aloft over the region turns southerly.
This will allow for more moist air from the Pacific to move into the
region. Atmospheric instability will begin to increase starting
Tuesday, followed by the potential for showers and thunderstorms
Wednesday and Thursday. Thunderstorm potential will shift east of
the Cascades on Friday. Precipitable water anomaly values are high,
pointing towards mostly wet thunderstorms. Fuels will be dry enough,
however, that any lightning could prove problematic. Additionally,
too much mid-level moisture may allow for enough cloudiness to put a
damper on the threat for thunderstorms, particularly on Thursday.
More details will be available as we get into next week. We will
continue to closely monitor how the pattern evolves.
