.PREV DISCUSSION...
SHORT TERM...Tonight through Friday...A weak upper level system
will move southeast across the eastern portion of the CWA 
overnight, spreading light showers mainly into the higher terrain
on the Idaho side. Upslope showers will also form in southeast 
Owyhee County and southern Twin Falls County. These showers will 
dissipate as the system moves away early Thu, and we will be
mostly clear, dry, and cool Thu afternoon through Friday. Our
upper level flow will shift from northerly to northwesterly by
Friday afternoon.

LONG TERM...Friday night through Wednesday...Northerly flow 
aloft will continue to bring below-normal temperatures to the 
area through Monday morning. Temperatures will be about 10 degrees
below normal before a warming trend begins on Monday afternoon. 
This could also bring a hard frost and the first freeze of the 
season to agricultural areas. High pressure builds over the region
on Tuesday and Wednesday allowing temperatures to warm back to 
normal or even a few degrees above normal. It will be dry through 
the period under mostly clear skies.
