NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
835 PM MDT Monday Aug 31 2015 


Discussion...weak zonal flow over the region will transition to 
a southwesterly flow before sunrise as the trough off the Pacific 
coast deepens and pushes further south. Skies will be mostly 
clear tonight under the influence of this dry pattern. Expecting 
winds to pick up Tuesday afternoon as upper level winds mix down 
to the surface. Forecast is on track...no updates. 


&& 


Aviation...VFR across southeast Oregon and SW Idaho. Any smoke 
layers or reduction in visibility due to wildfire smoke will be in 
the vicinity of the kbke and kmyl terminals and points north and 
west. Light surface winds overnight will increase Tuesday afternoon 
across southeast Oregon. West-SW winds 15-25 kts aloft through Tuesday 
afternoon. 


&& 


Previous discussion... 
short term...tonight through Wednesday...zonal flow will 
transition to a southwesterly flow aloft as an upper trough digs 
into the Pacific northwest. The southwest flow will direct a warm 
and dry air mass into the area on Tuesday. Highs will be above 
normal. Some of the southwest winds will mix down to the surface 
in the afternoon for gusty winds across southeast Oregon and the higher 
terrain of SW Idaho. A dry cold front will move through Tuesday 
night. Temperatures will be several degrees lower on Wednesday 
following the front. Another cold front will approach the area 
from the northwest...reaching Baker County by late afternoon. 
Moisture and instability along the front are both marginal...but 
enough to continue a slight chance of showers. Breezy southwest 
winds will develop again during the afternoon...shifting to the 
northwest in Baker County behind the front late in the afternoon. 


Long term...Wednesday night through Monday...models in fairly 
good agreement but differ on timing...placement and amount of 
precipitation. Axis of a long wave trough along the West Coast 
will begin to slowly shift east Wednesday night with the base of 
the trough continuing to dig south. This trough slowly opens up 
as it moves east with the axis of the trough over the forecast 
area by Saturday morning. Models indicated a cold front will 
move over the area late Wednesday night into Thursday but models 
differ on how far south precipitation will be. At this time 
looks like precipitation will be limited to Baker County Oregon 
and the west central mountains in Idaho. Front seems to stall 
over the area Thursday night and Friday with precipitation 
continuing over the west central mountains. As the axis of the 
trough moves over the region Friday night and Saturday 
precipitation will be pushed to the east but as the axis of the 
trough shifts to eastern Idaho Saturday night into Sunday could 
see increasing precipitation from the west. Confidence in 
location of precipitation over the forecast area is low but 
thinking is that any precipitation will be confined to northern 
zones Sunday through Monday. Temperatures will cool over the 
forecast area as the trough moves into the region. High 
temperatures on Thursday will cool 10-15 degrees from Wednesday/S 
highs. Temperatures will be the coolest Friday and Saturday with 
highs around 70 in the lowest valleys and highs in the mountains 
in the 60s. Temperatures will slowly warm Sunday and Monday with 
high temperatures a few degrees below normal by Monday.
