.SYNOPSIS...
The region will remain in a mild southwest flow through Wednesday,
with slight shower chances coming toward the Cascades and northern
mountains. Cooler, more seasonal temperatures follow the passage
of a weak cold front Thursday. Thursday will also be locally
breezy with a chance for light rain showers. More sunshine and
lighter winds return on Friday, with warmer temperatures this
weekend.

.DISCUSSION...
Evening update: watching some of the energy coming up through
Oregon and along the Pacific Northwest coast. Thicker clouds and
some radar returns showing up southwest of Portland and off the
Washington coast. Newest model runs, including the HRRR and the
Hi-res NAM, show some of this moisture sliding up north toward
the Cascades overnight into Wednesday morning. As such I added a
slight chance of showers toward the Cascades for after midnight,
mainly south of Lake Chelan, with the chances expanding northward
toward Canadian border by morning. Some sprinkles are possible
toward the lower elevations including the Wenatchee area,
Waterville Plateau and Okanogan Valley toward the Okanogan
Highlands as well. Otherwise I increased sky cover slightly.
Overnight lows and tomorrow afternoon`s highs generally look on
track. /J. Cote`

.AVIATION...
06Z TAFS: High pressure shifts east and the southwest flow brings
moisture and energy up from the south into Wednesday, while a cold
front approaches Wednesday night (into Thursday). Look for some
middle and high clouds, thickening especially Wednesday. A slight
chance of showers comes to the Cascades. A few sprinkles may slip
by EAT between 09-15Z, but somewhat better chances comes after
00Z Thursday (Wednesday evening) when the main system approaches.
Even then precipitation is not expected to be significant. Some
smoke from near wildfires may lower VIS toward MVFR conditions
around PUW and LWS Wednesday morning. Otherwise look for VFR, dry
conditions. /J. Cote`
