.DISCUSSION...An area of showers is moving ENE across eastern
Oregon and southwest Idaho this morning, with the heaviest showers
over northern Malheur County as of 9:30 AM MDT. Light rain should
get as far east as Boise between then and Noon. This afternoon,
showers will move off to the northeast, but new showers and
isolated thunderstorms will develop from Baker County east through
the West Central Mountain zone. We will do an update to increase
the chance of precipitation this afternoon and bring it farther
south. No other changes planned at this time.

.PREV DISCUSSION...
SHORT TERM...Today through Friday night...Pacific trough will
weaken as it comes inland into a stronger upper ridge anchored 
over the interior western US. The trough will bring widespread 
middle and high clouds but showers and isolated late-day 
thunderstorms will be confined to Baker County and the west 
central Idaho Mountains. Showers will exit east late tonight,
and clouds will decrease from the west Thursday. Another Pacific 
trough will bring more clouds and slight chance of showers and 
late-day thunderstorms to our far northern mountains Friday and 
Friday night. The two Pacific troughs will flatten but not 
dislodge the upper ridge over the interior western US, so our
CWA will continue to gradually warm through Friday. However, due 
to the greater cloud cover we lowered forecast max temps a couple 
degrees for today. Thursday will be sunnier and warmer, and
warmer again in the south Friday. Northern areas will be slightly
cooler with more clouds Friday. Winds will be light diurnal through
Friday night.

LONG TERM...Saturday through Wednesday...Showers and thunderstorms 
will increase on Saturday afternoon ahead of a cold front. 
Temperatures will cool around 10-15 degrees behind the cold front, 
with scattered showers and thunderstorms over the area through 
Monday. Models have significant precipitation with this system, as 
precipitable water values will be in the 95th-98th percentile for 
this time of year, which is around 1.00 inch at Boise. The potential 
of flash flooding will exist with values this high. Cooler and dry 
conditions Tuesday and Wednesday with temperatures around 5-10 
degrees below normal.
