NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
306 PM MST Sat Dec 20 2014 


Short term...strong Pacific storm will bring heavy precipitation and rising 
temperatures through Sunday. Valley rain and mountains snow will 
become all rain late tonight below 7000 feet mean sea level. Very strong 
westerly winds aloft will cause surface winds to increase to 
advisory speeds Sunday in all southern zones...including southern parts 
of Harney and Malheur counties in Oregon...and oyhwee and Twin Falls 
counties in Idaho. Also...avalanche danger will become high Sunday 
in The Sawtooth Recreation Area. Precipitation will decrease Sunday night as 
upper winds change to northwesterly while an upper ridge amplifies 
off the coast. Sunday will be quite warm and Monday will be about 
10 degrees cooler but still about 5 degrees above normal for the 
first day of winter. Winter begins at 403 PM MST Sunday. 


Long term...Monday night through Thursday...moist northwesterly 
flow will turn northerly Tuesday morning as an upper level ridge off 
the West Coast amplifies bringing drier conditions to our region. 
This setup allows an Arctic cold front to slide southward along the 
Front Range of the Rocky Mountains into the Great Plains...well east 
of the area. Trough moving southward along the British Columbia 
coast will temporarily deflect the ridge over the area Wednesday 
before a strong cold front arrives late Wednesday night into 
Christmas morning. Temperatures Wednesday will be well above normal 
before dropping Christmas day. Expect snow levels to drop to the 
valley floors with this cold front...with a chance of a white 
Christmas. 


Thursday night through Saturday...a cold northwesterly flow will 
affect the region for the majority of this period in the wake of the 
previous cold front. This will keep temperatures dancing around 
normal. Best chance for precipitation will be in the west central 
and Boise Mountains Thursday night. Snow levels will be low... 
precipitation should come in the form of snow. Timing of the 
next short wave trough and how much moisture it will bring are still 
unclear...but there is a chance of precipitation in the mountains 
again for Saturday night. 


&& 


Aviation...MVFR conditions with areas of IFR in widespread 
precipitation. Mountains obscured. Snow levels around 5000ft rising 
to 9000ft in southeast Oregon and 7000 feet in central Idaho mountains 
overnight into Sunday. Surface winds...SW 10-20 knots in southeast Oregon... 
SW 5-15kt in Idaho mountains...and southeast 10-15kt in Baker County... 
the Magic Valley...and the Treasure valley. Winds in southeast Oregon will 
increase Sunday afternoon to westerly 15-25kt with gusts to 35kt 
during the afternoon. Winds aloft at 10k feet mean sea level...westerly 25- 
35kt becoming northwest 45-70 knots by 00z Sunday...strongest in Oregon... 
then becoming northwest 60-80kt by 09z sun.
