NWS Forecaster Discussion




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


Discussion...weak convection...probably just virga...has formed 
and/or moved into northwest Harney and Baker counties this evening. 
Otherwise clouds are mostly clear and winds are light. We are 
still looking at a hot weekend with increasing moisture followed 
by a notable cool-down on Monday. No changes. 


&& 


Aviation...VFR. Scattered middle level clouds over central Oregon. Variable 
winds 10kt or less up through 10k feet mean sea level. 


Weekend outlook...VFR. Partly cloudy Saturday. Isolated 
thunderstorms developing mainly Sunday afternoon and evening. 


&& 


Previous discussion... 
short term...no 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. 


&& 


Boi watches/warnings/advisories... 
Idaho...none. 
Or...none.
