NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
843 PM MDT Tuesday Oct 21 2014 


Discussion...a few leftover showers north and east of McCall this 
evening will dissipate by 06z leaving mostly clear skies. Still a 
good probability of fog developing in mountain valleys after midnight 
and lasting into Wednesday morning. Current forecast has this well 
covered though did move back the timing to 06z given cloud cover 
trends on the infrared satellite. Dry and clear elsewhere across southeast 
Oregon and SW Idaho tonight. Will see too much of an east-southeast wind in 
the Snake Valley to allow for fog development. 


&& 


Aviation...VFR for much of southeast Oregon and SW Idaho tonight. 
Exception will be areas of IFR due to fog development in mountain 
valleys from late tonight through Wednesday morning. Surface winds 
less than 10 kts tonight increasing to 15 kts on Wednesday. 
Southwest winds aloft increase to 20-30 kts at 10k feet on 
Wednesday. 


&& 


Previous discussion... 
short term...tonight through Thursday...upper trough will shift 
to the east with showers decreasing over the Boise/west central 
mountains this evening. An upper ridge will move in late tonight 
accompanied by decreasing clouds and light winds. Mostly clear 
skies and light winds...combined with recent rains...are 
ingredients favorable for fog in the northern mountain valleys late 
tonight through Thursday morning. The ridge will shift to the east 
on Thursday as a moist SW-NE oriented Pacific plume enters the 
Pacific northwest Wednesday night. The plume will slowly enter southeast 
Oregon and portions of SW Idaho /excluding the western Magic 
Valley/ Wednesday night and Thursday. The plume is prognosticated to 
weaken and narrow as it approaches the area...thereby limiting the 
quantitative precipitation forecast amounts. The more favorable areas for showers will be in the 
higher terrain across the north. The gusty west-northwest winds in the 
western Magic Valley will diminish this evening. Winds throughout 
southeast Oregon and SW Idaho will be mainly SW-southeast tonight through 
Thursday...and become breezy Wednesday afternoon through 
Thursday. High temperatures will warm to slightly above normal on 
Wednesday...then cool to below normal on Thursday due to the 
clouds and showers. 


Long term...Thursday evening through Sunday...moisture will 
stream into the region Thursday night on SW flow aloft in advance 
of a strong and deep trough that won't move in until Saturday 
night and Sunday. In the meantime...precipitation will move north of the 
area Friday as a warm front swings up into Washington and northern 
Idaho...leaving US in the warm sector. This will allow temperatures to 
warm up above normal. Friday night will be dry and blustery as the 
strong trough approaches. Showers will move in Saturday as a 
strong cold front blows through. Winds will be moderate to strong 
over much of the area...especially in and near the showers. Sunday 
will be cool and blustery with a continuation of showers... 
especially in the west-central and Boise Mountains. 


Sunday night through Tuesday...the trough will move out Sunday 
night with a weak ridge building in behind it. The ridge will be 
short lived as the next trough slowly starts to spin up over the 
Pacific in its wake. Temperatures will be about normal for this 
time of year with chances of precipitation mainly over the higher 
terrain.
