  breezy winds through Wednesday.
- Mostly cloudy and dry Thursday.
- Showers and cool temperatures this weekend into early next
  week.

.SYNOPSIS...
Cooler and wetter weather pattern will stick around this week
with several opportunities for showers and very isolated
thunderstorms.

&&

.DISCUSSION...
The unsettled Spring-like weather pattern we`re currently under will
continue with another round of showers and afternoon thunderstorm
chances (15-30%) today. The area most expected to see any
thunderstorm development is far northeast Washington and far
Northern Idaho. A few hundred J/kg of instability resides over
this area per latest ensemble guidance. The upper level Low
will further slide southeast across the Rockies while another
trough moves southeast along the BC/Alberta Rockies into
Montana.

The PacNW will remain in a cool and unsettled pattern
leading into the coming weekend, with a one- off break on
Thursday. Friday and Saturday don`t look as great for
thunderstorm development (10-15% probability in coverage for
eastern WA and the ID Panhandle). Precipitation amounts range
from less than 0.10" to near 0.25" Friday across eastern WA, the
ID Panhandle including the WA and ID Palouse to the north-
central Washington Okanogan Highlands and Okanogan Valley on
Saturday. Sunday will feature a more robust weather system to
bring higher amounts of precipitation to the central Idaho
Panhandle and far southeast corner of WA. Into the early part of
next week, the unsettled series of shortwave features will
continue to bring showers and cooler, but near seasonal normal,
temperatures to the Pacific and Inland Northwest. Another taste
of Spring before we truly step into Summer. /Dewey

.AVIATION...
18Z TAFS: A moist boundary layer combined with low level upslope
flow into NE WA/N ID Panhandle will continue to promote areas of
MVFR stratus this morning, with VFR conditions across Central WA
where downslope northwest winds will persist through this
evening. Heading into the afternoon, showers will again increase
across NE WA/ID Panhandle along with a 15-30% chance of
thunderstorms. The highest potential for thunderstorms will be
north of KGEG/KSFF/KCOE so did not include a mention for any of
the TAF sites. Overnight into Thursday morning showers come to
an end (except the N ID Panhandle) as a short wave ridge moves
over the area.

FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS:
High confidence that MVFR conditions will persist through 19-20z
over NE WA/N ID Panhandle, with improvement to VFR after that as
boundary layer mixing helps raise the cloud heights. Although
localized MVFR conditions are possible under any heavier showers
or thunderstorms this afternoon. JW

Confidence descriptors:

Low - Less than a 30 percent chance
