.SHORT TERM...Tonight through Tuesday...High clouds will 
spread across eastern Oregon tonight and western Idaho Monday.
A Pacific trough will spread light rain inland as far east as
Harney County Monday morning and the rest of eastern Oregon
Monday afternoon.  Light rain will slowly spread into western
Idaho Monday night, and increase in eastern Oregon.  All areas
will be wet Tuesday as the Pacific trough comes inland.  Total
QPF through Tuesday will be .25 inch or less in Idaho, but .20
to .40 inch in eastern Oregon, heaviest in Harney County.  
Models show enough instability for a slight chance of 
thunderstorms Tuesday afternoon in southern Harney County.  
Low temps tonight will be 5-10 degrees warmer than last night 
as clouds increase.  Highs Monday will be a little cooler than
today in eastern Oregon as pcpn begins.  In western  Idaho highs
will be a little warmer Monday, but cooler Tuesday.  Snow level 
Monday and Monday night will be 6000-7000 feet in eastern Oregon
and 5500-6500 feet in western Idaho.  On Tuesday the snow level
will range from 6500 feet north to 7500 feet south.  No 
significant winds through Tuesday except near thunderstorms 
Tuesday afternoon.

.LONG TERM...Tuesday night through Friday...Lingering showers 
as the upper level trough continues to press eastward at the 
start of the period. A brief break early Thursday morning as a
weak ridge builds over the region ahead of our next weather-
maker. A weak trough out ahead of a much wetter, stronger
system will make its way through the area from the west late
Thursday into Friday.  The stronger system will bring widespread
showers back to the region. Temperatures sit a few degrees above
normal throughout the forecast period.

Friday night through Sunday night...Showery and breezy conditions 
are expected as a progressive, unsettled weather pattern continues
to dominate the region. Look for a strong upper level disturbance 
to roll through on Saturday bringing the more intense rain showers
and windy conditions. Snow is still a possibility in the higher 
mountains. Afternoon thunderstorms are also possible with this 
system. The next, but weaker upper disturbance is expected to brush
through the area Sunday.

.AVIATION...VFR. Increased mid to upper level cloud cover throughout 
the afternoon. Surface winds light and variable. Winds aloft to 10k 
feet MSL, westerly 10-15kts.
