NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Boise Idaho 
300 PM MDT Friday Jul 31 2015 

Short lightning yet in or near our County Warning Area. The nearest 
lightning as of 2 PM MDT was still in the central Sierra Nevada near 
Truckee California. Middle and high-level monsoon moisture was still 
flowing north in the Sierra then NE across central Oregon. Moisture 
will gradually increase along this track late Saturday through Sunday 
while temperatures continue to slowly rise. Saturday now looks warmer 
than Sunday as clouds may limit heating Sunday. The chance of 
thunderstorms will increase late Sunday along our southern County Warning Area border as 
well as in the central Idaho mountains and Blue Mountains in Oregon. 
Little change in temperature from previous forecasts. 

Long term...Sunday night through Friday...with the upper level 
ridge shifting east of The Rockies...average daily temperatures will 
trend downward from a few degrees above normal Monday to a few 
degrees below normal Thursday and Friday. Monday through Wednesday 
moist and unstable air will provide favorable conditions for 
isolated thunderstorms...triggered by weak disturbances in the 
southwesterly flow aloft. Wednesday through Friday models differ on 
timing an upper level trough as it approaches from the northwest 
coast. But they do agree that drier more stable air from the west 
will decrease the chance of thunderstorms...which will be mainly 
confined to the central Idaho mountains Thursday and Friday. 


Aviation...VFR under clear skies. Winds surface and aloft... 
variable 10 kts or less. 

Weekend outlook...VFR. Eastern Oregon...isolated thunderstorms 
Saturday...and again Sunday afternoon and evening. Southwest 
Idaho...isolated afternoon and evening thunderstorms over the west 
central Idaho and Boise Mountains...and south of the Snake River
