Area Forecast Discussion
National Weather Service Boise ID
904 PM MDT Sun Jul 14 2019

.DISCUSSION...Storms are not as widespread as last night, but some
significant storms in eastern Oregon have produced a strong gust
front that is moving through the Treasure Valley at this time.
Wind gusts near 50 mph are moving east and will continue toward
Mountain Home through 10 pm. Blowing dust is reducing visibility
to near 1 mile in some places. Otherwise, storms continue over
northern Harney County, in the Upper Weiser River Basing and
across Malheur County. Latest mesoscale guidance indicates
isolated storms through midnight, with the possibility of storms
developing near Mountain Home and moving into the Boise Mountains
after midnight. Will update to allow for this possibility.

&&

.AVIATION...Mostly VFR. Local IFR caused by thunderstorm outflow 
moving through the Treasure Valley coupled with blowing dust and 
wind gusts up to 50kts through 04Z. Isolated showers and 
thunderstorms moving across higher elevations of SE OR dissipating
after sundown. Surface winds: west-northwest 5-10kts with 
25-35kts in and around thunderstorms and local gusts in the 
Treasure Valley up to 50kts. Winds aloft to 10k feet MSL: west-
southwest 15-25kts.

.PREV DISCUSSION...
SHORT TERM...Showers and thunderstorms will develop along the nw 
CWA border (Baker County and nw Harney County) this afternoon and 
spread slowly east tonight as an upper trough comes onshore from
the north Pacific.  The strongest storms will have hail and wind
gusts to 50 mph.  Only a few thunderstorms are expected in Idaho
south of the Snake Basin.  On Monday showers and storms will  
develop along our northern CWA border then shift to the Idaho 
side Idaho Monday night as the upper trough comes further inland.  
Temperatures will cool Monday and hold steady (i.e., about 5 
degrees below normal) on Tuesday.  No significant winds through 
Tuesday.

LONG TERM...Tuesday night through Friday...Dry northwesterly flow 
aloft will bring cooler temperatures than what we've been seeing, 
but still remain close to normal. The upper level flow will start 
to shift back to the southwest by Friday which will begin a warming 
trend once again.
Friday night through Saturday night...Clear and warmer are the 
expected conditions as drier, southwest flow dominates. High and
low temperatures are expected to register in near normal.
