.SYNOPSIS...
A passing cold front continues to bring showers and
thunderstorms through Thursday. Mild and dry weather is likely for
Friday followed by heat Saturday. The next system will move
through on Sunday with more wind and thunderstorms. Mountain
showers and seasonal temperatures will continue through the early
week. Temperatures look to trend warmer and drier by the middle to
the end of next week.

.DISCUSSION...

Today through Friday night: The upper level trough will continue to
slide through the region. The chance of thunderstorms expands on
Thursday to Eastern WA and the ID Panhandle, with lightning being
the main concern. The timing of these storms looks to start late
morning, continuing through the afternoon as they move east. Breezy
winds will continue through the morning with increasing speeds into
the afternoons. Gusts of 30 to 40 mph will be common across the
Columbia Basin extending east towards Spokane and the Palouse.
Humidity will be higher which will decrease the threat of fire
concerns. Temperatures will be cooler today, with highs in the 70s.

A ridge move in behind todays system, leading to a mild, dry Friday.
A few lingering showers are expected over North Idaho through the
morning. Highs will be in the upper 70s and 80s. Lows will be in the
50s. /KM

Saturday through Thursday: Saturday will be mostly dry and mild
thanks to a shortwave ridge. There is a small chance (20%) of
showers at the Cascade crest and Okanogan Highlands Saturday
afternoon thanks to deep moist southwest flow. Temperatures will be
in the 80s to low 90s.

Thunderstorm chances increase Sunday as a trough comes ashore. The
moist system will need to be monitored to flash flooding potential,
especially vulnerable burn scars. Winds behind the front passage
will be breezy Sunday evening, but fire risk should be reduced
thanks to the moist nature of this system. Precipitation chances
stick around through late next week as the progressive pattern
continues.

.AVIATION...
06Z TAFS: An upper level trough of lower pressure will shift
across the Inland Northwest tonight. Dynamics ahead of the trough
will keep showers with embedded thunderstorms going near the
Canadian border through the night. A band of developing cloud
cover along the leading edge may produce light precipitation in
the vicinity of KPUW and KLWS, but mostly only expecting overcast
mid level clouds with precipitation developing further east of
these airports. Westerly winds will remain gusty in the lee of the
Cascades and out over the basin tonight through Thursday. Expect
gusts of between 20-30 kts, especially through the morning into
the afternoon with better mixing potential. The cold pool
associated with the upper trough and diurnal heating in the
afternoon will destabilize the atmosphere with widely scattered
showers and embedded thunderstorms mainly across northeast
Washington and into the Idaho Panhandle.

FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS:
High confidence in VFR conditions through the TAF period. There is
a 20 percent chance for thunderstorms across the Spokane/Coeur
d`Alene corridor in the afternoon on Thursday. /SVH

-----------------------

Confidence descriptors:
Low - Less than a 30 percent chance
Moderate - 30 to 70 percent chance
High - Greater than a 70 percent chance
