Synopsis...

Moderate precipitation will continue to fall tonight into Thursday
as a low pressure system slowly sags through the region. A cold
front will follow on Friday for showers, gusty winds and cooler
temperatures that will last through the weekend and into Monday. A
return to warmer temperatures and drier conditions is expected next
week.

Discussion...
made some tweaks to chances for precip and rainfall amounts. Edits
were mainly made over the Palouse to the central Panhandle mtns.
There is a swath of light rain over that area early this evening.
It is a bit further south than what was previously in the
forecast. I don't expect it to rain much longer across this area
with models consistent in lifting this moisture northward late
this evening into the overnight hours. Rain is expected to lift up
into the northern mtns overnight with a short break expected as
far north as the Spokane/Coeur D'Alene corridor. The cold front
will then begin to sag moisture back over the basin and into the
Spokane area by tomorrow morning. /Svh

Aviation...

00z tafs: a moist warm front with a modest 50 kt low level jet at
850 mbs will impact the region overnight into Thursday morning.
The low level jet will be focused primarily from around kdls to
khri through the Columbia River gorge, across the upper Columbia
Basin and into the Spokane/Coeur D'Alene corridor. Low level wind
shear can be expected through this corridor with around 45 kt
winds possible down to between 1500 and 2000 ft agl at kgeg, ksff
and kcoe. Rain will lift northward through the evening with a
break expected at all taf sites overnight (between 06-12z). The
approaching cold front will then begin to shift the rain shield
further eastward and impact most taf sites except for klws
Thursday morning and afternoon. There is a possibility for MVFR
cigs at kmwh, kgeg, ksff and kcoe with the rain on Thursday. /Svh
