NWS Forecaster Discussion

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

Discussion...minor changes made to the grids this evening...but 
current rain showers are developing in areas of adequate probability of precipitation. 
Lowered probability of precipitation in the Idaho central mountains until midnight. Kept 
higher chances in for midnight to 6 am in Idaho central mountains 
and added some isolated mention for the owyhees as models are 
indicating that current convection in the southern Highlands will 
slowly shift east overnight. Also lowered temperatures a bit in 
areas of cloud clearing...mainly Ontario and areas northwest. 


Aviation...VFR through Friday. Scattered showers and middle-level 
ceilings will continue in a thin band stretching across SW Idaho 
tonight. Clearing to the west will allow for patchy fog and IFR 
conditions to develop in valleys of the west central mountains Friday 
morning. Will see increased shower development across southeast Oregon 
Friday afternoon. Northwest surface winds 10 kts or less overnight 
increase on Friday afternoon. S-SW winds aloft to 30 kts through 
10k feet mean sea level. 

Weekend outlook...a cutoff low pressure system will bring periods of 
rain to southeast Oregon and SW Idaho through Saturday night. Low VFR and 
local MVFR ceilings will accompany heavier showers across southeast Oregon 
Saturday and SW Idaho Saturday night. VFR conditions Sunday with 
decreasing clouds west to east. Gusty westerly winds surface and 
aloft Saturday will weaken on Sunday. 


Previous discussion... 
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.
