NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
308 PM MDT Thursday Sep 3 2015 


Short term...tonight through Saturday...upper low centered over 
southern British Columbia will dive south...reaching western 
Oregon on Friday. The low will then move eastward and enter southeast 
Oregon/SW Idaho on Saturday. A band of showers /over SW Idaho/ 
ahead of the low will weaken this evening...then re-strengthen 
over the central Idaho mountains late tonight and remain nearly 
stationary through Friday. Meanwhile...showers accompanying the 
upper low will spread into southeast Oregon during the afternoon. 
Instability associated with the cold upper low will lead to a 
slight chance of after-evening thunderstorms. The showers will continue 
Friday night-Saturday...with most of the activity occurring over 
the higher terrain. The Treasure and western Magic Valleys will 
receive little to no rainfall...while the mountains will receive 
total amounts of up to an inch through Saturday. Snow levels will 
drop considerably by Saturday morning...with the lowest levels 
near the upper low center. Snow levels could be down to around 
6000 feet in southeast Oregon and 7500 feet in SW Idaho by Saturday 
morning. Light snow accumulations are possible above these 
elevations on Saturday. Due to the proximity of the cold upper 
low...the instability will once again support a slight chance of 
afternoon thunderstorms. Temperatures will be below normal on 
Friday...and around 5-10 degrees lower on Saturday when valley 
highs will only be in the 60s. Locally breezy northwest winds are 
expected each afternoon. 


Long term...Saturday night through Thursday...upper level trough 
will move out of the region Sunday leaving the region in cool 
northwesterly flow. Dry conditions expected through the remainder 
of the period. Temperatures will slowly moderate after Sunday to 
around normal by Wednesday. Temperature forecast confidence beyond 
Monday is low as models have a different handling of the tropical 
systems in the central and eastern Pacific Ocean. 


&& 


Aviation...VFR. Broken-overcast middle level ceilings. Light low-VFR 
showers over central Idaho mountains with mountains obscured in 
that area. Partial clearing overnight. Surface winds generally northwest 
5-15kt. Possible fog overnight in sheltered mountain valleys. 
Winds aloft at 10k feet mean sea level...SW 15-25kt. 


Weekend outlook...cutoff low pressure system will bring periods 
of rain...low VFR and local MVFR ceilings to southeast Oregon and SW 
Idaho Friday and Saturday. VFR conditions with decreasing clouds 
on Sunday. 


&& 


Boi watches/warnings/advisories...
