NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
1037 am MST Monday Dec 22 2014 


Discussion...northwest flow today will keep snow showers going in 
the mountains...especially along west facing slopes...and bring 
gusty winds to the Snake River Plain. Have made updates to the 
forecast to increase probability of precipitation across the west central and eastern 
Boise Mountains through this afternoon...though precipitation amounts 
will be light. Winds in the western Magic Valley are already 
higher than most model guidance so have increased speeds there for 
this afternoon. This brings them up to advisory criteria...and 
there is now a Wind Advisory in place for the western magic and 
southern Twin Falls County zones through early evening. Fog 
development tonight will be the next consideration for the 
afternoon package. 


&& 


Aviation...MVFR ceilings improving to VFR by this afternoon. Expect 
IFR -shsn to continue in central Idaho mountains through 00z Tuesday. Mountains 
obscured. Areas of MVFR-IFR fog and stratus overnight. Surface winds 
generally northwest 5-15kt...stronger northwest 15-25kt with gusts to 35kt in 
upper Treasure and Magic Valleys. Winds aloft around 10k feet 
mean sea level...northwest 30-45kt becoming northwest 25-35kt. 


&& 


Previous discussion... 
short term...today through Tuesday...long fetch of deep Pacific 
moisture streaming into the region will end by midday as an upper 
ridge amplifies off the West Coast...thereby pinching off the 
moist northwest flow. Latest radar images continue to show light 
precipitation in the moist northwest flow moving through portions of southeast 
Oregon and SW Idaho...including the Treasure valley...early this 
morning. The precipitation will gradually lessen through the morning and 
become spotty this afternoon. Precipitation will end this evening as the 
amplifying ridge starts to work eastward toward the area. The 
ridge will move into the area on Tuesday for dry weather across 
all of southeast Oregon and SW Idaho. Clearing skies and lighter 
winds...along with moisture from recent precipitation...will lead to 
patchy valley fog late tonight through Tuesday morning. 


Winds will increase and become windy especially in the western 
Magic Valley later this afternoon. Winds will diminish this 
evening. Light winds are expected on Tuesday as high pressure 
builds into the region. Temperatures will remain above 
normal...although the highs on Tuesday will be slightly cooler 
than today. 


Long term...Tuesday night through Monday. Drier conditions will 
continue Tuesday night through middle day Wednesday as the high 
pressure sitting off of the California coast begins to flatten 
out. The next trough and associated cold front are set to move 
into the area on Wednesday night/Thursday morning. Models are in 
decent agreement of a cold front moving through from northwest to southeast 
between 03z and 15z Thursday morning. However...the European model (ecmwf) and GFS 
now agree on bringing the main center of the trough to our 
south...which delays the cold front slightly...while the NAM is a 
bit quicker with this system. Nonetheless...it will bring colder 
temperatures and drop snow levels to or near valley floors behind 
the front...and after the bulk of moisture. Conditions will dry 
and remain cold as the area transitions into a northwest flow 
later on Thursday. Yet another trough is expected this weekend 
with a much more northerly fetch which will bring another chance 
of precipitation...mainly snow...and keep temperatures at or below 
normal.
