NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Boise Idaho 
313 am MST Tuesday Dec 1 2015 

Short through Wednesday...situation is beginning to 
change this morning as the low clouds have eroded in the western 
Magic Valley and into much of Elmore County...while still hanging 
tough along the Snake River as seen at kmuo. A middle-level cloud 
deck is moving east across Harney County and into Malheur County 
at this time...and this will complicate matters today as it 
continues to move east even as it dissipates through the morning 
hours. These middle-level clouds are associated with a weak short- 
wave trough that is weakening further as it enters a ridge axis 
that is pretty much right over our area. Although there could be 
some seeder- feeder flurries as this middle- deck moves over the low 
clouds associated with the inversion...we have not included this 
in the forecast as the odds seem slight. As we move into 
tonight...a much stronger and deeper upper level trough moves 
toward the Pacific coast and east to southeast winds will strengthen 
over much of the area as surface pressures fall to the west. This 
will help to further erode the inversion from the western Magic 
Valley westward. It is always difficult to guess how fast this 
process will play out...and therefore when to adjust temperatures for the 
end of the inversion and bring them more in line with what would 
otherwise be going on at this time. We are going most of the way 
toward bringing all but the lower Treasure valley out of the 
inversion by Wednesday morning...but at the same time middle and high 
level clouds associated with a leading short-wave trough... 
separate from the approaching large trough which will remain off 
the coast through the short term...will move into the area and 
limit heating. Precipitation will spread into eastern Oregon late tonight and 
into SW Idaho Wednesday morning...before this system dies out as it is 
eaten up by the ridge axis. Therefore...even though we expect the 
inversion to weaken over much of the upper Treasure valley Wednesday 
morning...temperatures Wednesday afternoon will still be well below normal. 
There is a chance of freezing rain Wednesday morning in mainly southwest 
and western Harney County as warm air overspreads the boundary 
layer. At this appears Burns will remain all snow...but 
points south and west of there may get a period of freezing rain. 
Later forecasts will be able to provide more clarity on this 
potential as models come into better agreement on snow levels and 
timing. For now...the chance of freezing rain is in the forecat 
but we have decided not to issue a west-southwest due to lack of confidence 
in occurrence. 

Long term...Wednesday night through Monday...models remain in 
fairly good agreement with the overall weather pattern but 
continue to disagree on timing and placement of precipitation. 
There is even changes from model run to model run on the timing 
and placement of precipitation so will trend the forecast towards 
a model blend. Moist southwesterly flow will develop over the 
region Wednesday night as the axis of a long wave ridge shifts 
east of the forecast area and a long wave trough over the Pacific 
moves closer to the West Coast. This moist flow will bring a 
slight chance of precipitation to southeast Oregon and the west 
central mountains of Idaho Wednesday night and Thursday. As the 
axis of the long wave trough moves inland precipitation will 
spread to the rest of the forecast area Thursday night with the 
best chance of precipitation on Friday as the axis of the trough 
moves over Idaho. Friday night and Saturday a weak ridge of high 
pressure will move over the region but models showing enough 
moisture in the flow for slight chance probability of precipitation over higher 
elevations. Saturday night and Sunday flow aloft will shift to the 
southwest as another long wave trough out over the Pacific 
approaches the West Coast for slight chance probability of precipitation mainly over the 
higher elevations. Sunday night and Monday the long wave trough 
will move over the area for increasing probability of precipitation over the forecast 
area. Still looks like enough cooling aloft to break the valley 
inversion by Friday with valley temperatures warming to near 


Aviation...low MVFR and local IFR conditions in low stratus and 
fog remain across eastern Oregon and southwest Idaho. As the 
surface high pressure shifts to eastern Idaho...with easterly low 
level winds developing...the low stratus and fog is being pushed 
to the west with kjer...ktwf and kmuo now under clear skies. Kmuo 
could see brief MVFR and IFR conditions this morning but thinking 
kmuo...kjer and ktwf will stay out of the stratus and fog. Areas 
above the stratus will see increasing high level clouds. Surface 
winds 10 knots or less. Winds aloft westerly 10-20 knots up 
through 10k feet mean sea level. 


Air stagnation...weak ridging aloft and high pressure to the east 
at the surface will allow the existing strong valley inversion to 
continue into Thursday in the lower Treasure valley and west of 
roughly Mountain Home in the upper Treasure valley. However... we 
do expect it to decrease in the western Magic Valley today and 
Wednesday. Winds are expected to increase in the Magic Valley 
tonight and Wednesday...which will improve mixing there. The Long 
Valley may have to wait until Friday for relief.
