.DISCUSSION...

...STRONG DRY COLD FRONT PASSAGE TUESDAY...

Today through Monday night: High pressure will continue to
amplify over the West Coast Sunday and start to shift inland
Monday as Gulf of AK low edges into British Columbia, which will
eventually push a dry cold front toward the area. For this period
it will leave dry conditions, with warming temperatures. Skies
will be mostly sunny to partly cloudy today, with some afternoon
cumulus again near the mountains and passing higher clouds.
Heading into Monday a broader area of middle to high clouds spills
in with moisture ahead of the approaching system. Wind will be
east to northeast today generally at 10 mph or less, but some
gusts of 15-20 mph are possible in the deeper Columbia Basin.
Winds turn to a west/southwest direction heading into late
morning to afternoon Monday, increasing in strength around
central WA to around 10-20 mph with gusts of 20 to 30 mph by
late afternoon to evening with the tightening cross-Cascade
gradient.

Highs today will be mostly in the 80s to low 90s. Monday highs
are forecast to be in the middle to upper 80s and 90s, with a few
spots that could push 100 in the deep Columbia Basin. Lows will
be in the 50s and 60s, with Monday night to Tuesday morning
with lows in the middle to upper 60s in the deeper basin
and Wenatchee Valley. Pockets of Moderate HeatRisk will be found
today near the Cascades and deeper Columbia Basin, with a broader
Moderate HeatRisk potential Monday.  Moderate HeatRisk affects
those who are sensitive to heat, especially those without
cooling/hydration, and some health systems and industries.

Tuesday: A cold front pushes across the area in the later morning
to early afternoon. The best lifts and deeper moisture stays north
of the border, leading to a dry cold front passage. Behind the
cold front, PWATs drop off to around 45-75% of normal which is
expected to lead to some dry afternoon RH levels into the
mid-teens to lower 20s over the basin.  It is possible those RH
values could even drop to the lower teens to near 10 percent
in the lee of the Cascades/Okanogan Valley.  Temperatures, while
a bit cooler than Monday, will see be very warm in the mid-80s
to mid-90s. Winds will breezy near the Cascade gaps in the
morning, then increase throughout the area in the afternoon
and evening before decreasing in the late evening into
overnight. Peak speeds of 20 to 30 mph are possible, with
gusts 30 to 50 mph. The NBM shows 20-50% chance of wind gusts
exceeding 50 mph and even a 5-10% chance of exceeding 60 mph
over the Waterville Plateau to Upper Columbia Basin.  This will
be due to a 140kt+ jet dropping south along the US/Canadian border
into eastern Montana and almost a 10-15 mb gradient between Seattle
and Wenatchee.

The hot, dry and windy set-up will bring elevated to possibly
critical fire weather conditions. The HDWI (Hot-Dry-Windy-Index)
reaches toward the 95th percentile of parts of basin.
Additionally, we will have to keep an eye toward blowing dust,
choppy waters, difficulty for high-profile vehicles, maybe
even some localized power outages and minor tree damage.

Wednesday to Saturday: The Inland NW will remain in a progressive
and dry pattern, with a northwest flow turning more westerly toward
the late part of the week as a weak offshore trough approaches.
Some cumulus build-ups are expected, especially around
the upslope flow into the eastern mountains, each afternoon
with periodic middle to high clouds. Wind will remain
breezy/gusty Wednesday from the west to northwest. Speeds
of 7 to 15 mph with gusts of 15 to 25 mph are possible, stronger
near the lee of the Cascades. Afternoon minimum RH values will
still be in the mid-teens to low 20s and fire weather conditions
will still be elevated, but not at much as Tuesday.  Winds will
be occasionally breezy near the Cascades/Okanogan Valley the
remainder of the week, but nothing as strong as Tuesday or
Wednesday. Temperatures will be above normal through the period,
though relatively cooler on Wednesday with upper 70s and 80s
and warming up toward the mid 80s to mid 90s Friday. /Solveig
