.PREV DISCUSSION...
SHORT TERM...Tonight through Saturday...Broad upper trough 
over the has brought relatively cool wx to our area.  Two
embedded lobes in the trough.  The first lobe will exit east
of us tonight so that Thursday will be a little warmer than
today.  The second will pass through Friday with another
cooler surge.  The coolest night will be Friday night when
lows will be 50 to 55 in the valleys and upper 30s and 40s
in the mountains and the plateaus in eastern Oregon. 
Saturday will begin a warming trend as the second lobe 
exits east.  There still is enough moisture tonight for 
clouds in our far north and even a slight chance of a shower
or thunderstorm in northern-most Baker and Valley Counties
this evening.  After that skies will be only partly cloudy
in the north and clear in the south through Saturday.  
Winds will be mainly from the west or northwest 5 to 15 mph
through Saturday, but locally 15 to 25 mph in the Snake 
Basin and southeast Oregon during the afternoons.

LONG TERM...Saturday night through Wednesday. Models continue 
to show the Four Corners High amplifying on Sunday and Monday.
This will put the area into a warmer southwest flow. This pattern 
will continue through mid week, and monsoon moisture will likely 
advect into the area, especially into Western Idaho. Afternoon 
showers and thunderstorms are possible, mainly on Tuesday and 
Wednesday.  Temperatures will increase a few degrees each day, 
and remain 4-8 degrees above normal through the period.
