NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Boise Idaho 
308 PM MDT Thursday Sep 18 2014 


..included air stagnation segment... 


Short term...at 2 PM MDT isolated thunderstorms continue in southeastern 
Owyhee County and the western Magic Valley...moving northeastward. Air mass is 
still unstable enough for thunderstorms to form in eastern Oregon... 
Owyhee Mountains...Camas Prairie...and eastern Boise County through 
this evening. Isolated coverage in these areas. Scattered 
coverage in the southern Sawtooths where air mass is more unstable. 
Air mass will dry and stabilize from the west later tonight. Friday 
through Saturday will be dry. Extensive smoke from fires in calif 
should decrease in our County Warning Area tonight and Saturday as upper winds 
veer from southwesterly to more westerly. But there are also fires in 
Oregon and some smoke will continue in our County Warning Area. Decreasing clouds 
late tonight will allow temperatures to cool further than last night. Maximums 
Friday should be slightly cooler than today. Mins Friday night 
similar to tonight. Maximum temperatures Saturday 3 to 6 degrees warmer with 
upper winds becoming southerly or even southeasterly...as upper low 
in California comes toward US. Southeasterly winds would be best 
for ridding our County Warning Area of remaining smoke. 


Long term...Saturday night through Thursday...a pattern change next 
week is expected to bring precipitation and cooler temperatures by 
Thursday. Temperatures will continue above normal through Wednesday. 
An upper level low over the California coast Saturday night will 
lift northeast across the Great Basin Sunday reaching southwest 
Idaho and southeast Oregon Sunday night...with a chance of showers 
Sunday afternoon through Monday. Precipitation is expected to be 
mainly over southwest Idaho and the central Idaho mountains. This 
system will be followed by drier southwest flow aloft starting 
Monday night and continuing across most the area through Wednesday. 
Meanwhile a strong upper level jet from the North Pacific will reach 
northern California Tuesday night and the northern rockies Wednesday 
night. This feature plus a surface cold front crossing southeast 
Oregon and southwest Idaho Wednesday night and Thursday will bring 
cooler temperatures and a chance of showers. 


&& 


Aviation...VFR. Widespread smoke layers aloft...plus local MVFR 
visibilities in the valleys...will continue through this evening. 
Some improvement is foreseen after midnight with the smoke shifting 
south of a kreo-kmuo-Fairfield line. Also expect isolated 
thunderstorms over the higher terrain and east of kmuo until about 
06z. Surface winds...variable 10 kts or less except westerly 10-15 
kts through the Snake River Valley east of kboi. Winds aloft... 
northwest 15-20 kts up through 10k feet mean sea level. 


&& 


Air stagnation...smoke from California fires should decrease 
tonight and Friday as upper winds change from southwesterly to 
west-southwesterly. But fires in Oregon will also contribute 
some smoke. On Saturday an upper level low pressure system will 
move in from Nevada. Circulation around the low will bring 
southerly and then southeasterly winds into our area and greatly 
improve air quality.
