.SYNOPSIS...
More autumn like weather is on the way for the remainder of the
work week. A slow moving cold front will bring an increased
chance of rain to central Washington for Wednesday and Thursday,
then showers will spread to eastern Washington and north Idaho
for Friday and Saturday. Cooler temperatures will follow the cold
front Thursday and Friday. A slight warming and drying trend is
expected for next week.

.DISCUSSION...
Early evening update: moisture continues to feed into the region
ahead of the slow-moving long wave trough. Based on
radar/satellite trends, as well as the HRRR/Hi-Res NAM, I
increased PoPs over the western Columbia Basin through the
northern mountains through the remainder of the evening. There is
also the isolated threat of showers around the Spokane/C`dA area
this evening. However as the night progresses the main threat
backs toward the Cascades. /J. Cote`

.AVIATION...
00Z TAFS: A moist southerly flow will continue ahead of a
slow-moving longwave trough. A warm front lifting through this
evening will carry light precipitation threat to most of the TAF
sites. However as the night progresses the main focus for
precipitation will shift west toward the Cascades and western
Basin, along the incoming cold front, after 06-09Z. That boundary
will slow or stall on Wednesday, keeping the main precipitation
threat toward EAT/MWH. A lower level easterly flow and increased
moistening of the lower levels into the Cascades will bring the
opportunity for MVFR cigs near EAT. Some rain threat will begin
to edge east again toward GEG by late afternoon or evening
Wednesday. Marginally breezy conditions are expected over the
eastern TAF sites toward mid-Wednesday. /J. Cote`
