NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
857 PM MST Monday Jan 26 2015 


Discussion...middle and high clouds are streaming in from the 
southwest in advance of an upper level system. This is still 
expected to move into southeast Oregon and SW Idaho Tuesday afternoon...and 
then spread NE into much of southern Idaho Tuesday night. Low clouds and 
fog persist this evening in much of Malheur County...although it 
is now largely obscured from satellite observation by the middle and 
high clouds mentioned previously. Have done a small update to 
modify the sky grids to allow for the incoming clouds. Have also 
lowered the min temperature forecast for Fairfield...which is already 
down to 14 degrees. Update out shortly. 


&& 


Aviation...VFR with scattered high clouds except for MVFR 
conditions in stratus across southeast Oregon. Expect the main area of 
stratus and patchy fog to be across the lower Treasure 
valley/Weiser basin and Long Valley later tonight through Tuesday. 
Winds and high/middle clouds will increase ahead of an upper low off 
the Southern California coast which should lift across the Great Basin on 
Tuesday. Rain will reach the Nevada/Idaho border Tuesday afternoon and 
shift northeast Tuesday night. Precipitation should remain 
southeast of a kreo-kboi- kmyl line. Surface winds light and 
variable...except in Magic Valley NE winds 15 kts. Winds aloft 
near 10k feet mean sea level...SW 15-20 kts...through 21z Tuesday. 




&& 


Air stagnation...continued inversion conditions through Tuesday. 
Upper level ridge will begin to break down later tonight as a 
trough approaches the area from the south. Inversion will weaken 
slightly as cooler temperatures aloft move over the area Tuesday into 
Wednesday before a return to inversion conditions later in the 
week. 


&& 


Previous discussion... 
short term...tonight through Wednesday...upper level ridge is 
beginning to move east. Temperatures aloft will slowly cool in 
response to a system moving up the California coast into the Great 
Basin tonight. Patchy fog is expected to form once again tonight 
in similar areas as last night. The dense fog that was in the 
lower Treasure valley overnight has lifted into a low stratus deck 
and could limit fog development under this area. Patchy dense fog 
remains in sheltered valleys of Malheur County. Next system 
arrives from the south Tuesday afternoon. The strongest dynamics 
of this system will move across eastern Idaho into Wyoming...thus 
expect the highest precipitation chances in the Magic Valley and 
areas eastward with minimal precipitation chances near Baker 
County. Snow levels will lower to around 5000 to 6000 feet mean sea level with 
this system. Precipitation will move out of the region by 
Wednesday morning with patchy fog developing in the sheltered 
valley locations of west central and Boise Mountains...and Treasure 
and Magic Valleys...as upper level ridging brings warmer temperatures 
aloft once again. 


Long term...Wednesday night through Monday...transient ridge 
Wednesday night will shift eastward. Split flow will then dominate 
the northwest but a weak moist upper level trough is now expected over the 
area Thursday night to Friday morning. Rex block over western 
North America is expected later Friday through Monday...with high 
pressure aloft over Idaho and lower pressure over aloft over old 
Mexico though model agreement is still low by late Monday with 
the operational ec more zonal and the gefs/ensemble ec and 12z GFS 
holding on to more ridging. Though disagreement that some moisture 
may reach northern tier zones so will have low probability of precipitation across the NE 
Oregon/central Idaho mountains late in the extended. Temperatures 5-10 
degrees above normal Friday-Sunday and near to a little above 
normal early next week.
