National Weather Service Boise Idaho
344 am MDT Sat Sep 23 2017

Short term...today through Sunday...upper level trough will work
eastward through Sunday bringing drier conditions and a slow
warming trend. The central Idaho and far eastern Boise Mountains
will keep scattered clouds and slight chance of showers for today.
Otherwise the region will be dry with high temperatures 3 to 8
degrees warmer than yesterday (though still well below normal).
Mostly clear skies will allow for another cold night with near
freezing temperatures possible in the western Magic Valley and
parts of the upper Treasure valley east of Boise by Sunday
morning. Sunday is continued dry with high temperatures warming
another 3 to 6 degrees from today. Open terrain will see breezy
conditions develop each afternoon as north-northwest flow aloft
mixes to the surface.

Long term...Sunday night through Friday...dry with a warming
trend. Sunday night through Tuesday our area will be under
northerly flow aloft on the eastern flank of an upper level ridge
centered off the West Coast. This pattern will keep temperatures a
few degrees below normal. High and mid level clouds embedded in
the flow will keep skies partly cloudy Sunday night into Tuesday,
but no precipitation is expected. Temperatures will be near normal
on Wednesday and slightly above normal Thursday and Friday as the
ridge moves inland over the intermountain region.
