NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
300 PM MST sun Dec 21 2014 


Short term...steady precipitation continues to come in from the northwest this 
afternoon and should last well into the night before decreasing. 
The warm front did not go as far north as expected and temperatures stayed 
relatively cool. Rain has changed back to snow at mountain sites 
above 6000 feet mean sea level and the snow level should continue to slowly 
lower through the night as precipitation continues. Also...winds have 
decreased below advisory levels in southern zones so the Wind 
Advisory has been cancelled. The Weiser river almost reached flood 
stage at Weiser but appears to have crested this afternoon. Other 
rivers were well within their banks. Otherwise...the previous 
forecasts still look good expecting precipitation to decrease to scattered 
rain and snow showers Monday and generally end late Monday. Tuesday 
will be a little cooler than Monday in the valleys but still 
slightly warmer than normal. Mountains sites will start warming 
again Tuesday as next Pacific upper ridge comes inland. 


Long term...Tuesday night through Friday...a more wintry upper 
level pattern on the way. An upper level ridge over the the West 
Coast Tuesday will be suppressed by cold upper level trough in the 
Gulf of Alaska Wednesday. As the ridge moves east a strong cold 
front and associated trough will move southeastward from the Gulf of 
Alaska into the Pacific northwest. Snow levels will fall to valley 
floors by Thursday morning...although it is still unclear whether 
snow will fall behind the front. Still a good chance to see 
snowflakes fly in the low valleys for Christmas day...travel through 
mountain passes could be tricky for Wednesday night into Thursday. 
GFS still does not have a good handle on this system because of the 
inconsistency...thus elected to use the European model (ecmwf) guidance. In wake of 
the cold front...expect temperatures around normal and precipitation 
to continue in the higher terrain mainly over The Blues...wallowas 
..and central Idaho mountains through Friday. Temperature forecast 
confidence beyond Thursday is low as any new snow cover will make 
temperatures colder. 


Friday night through Sunday...a cold northwesterly flow will affect 
the region through Saturday...becoming westerly by Saturday night. 
There is a chance of precipitation in the west central and Boise 
Mountains beginning Saturday night through Sunday. The turn in wind 
direction Saturday night indicates an approaching short wave 
trough which will bring a chance of precipitation to most of the 
region by Sunday night. Snow levels will be low...most precipitation 
will come in the form of snow...and temperatures will be near normal 
through the period. 


&& 


Aviation...widespread MVFR-IFR conditions with precipitation. 
Mountains obscured. Snow levels to the surface in central Idaho 
mountains ranging up to 10k feet mean sea level SW of the Snake River 
Plain...slowly falling through the night as band of precipitation 
moves south. VFR conditions south and west of a line from kbno-kreo 
in southeast Oregon. Surface winds westerly 15-25kt this evening in southeast 
Oregon and eastern Magic Valley east of kjer...northwesterly surface 
winds up to 15kt elsewhere. Northwesterly winds 20-30kt Monday 
afternoon in Magic Valley. Winds aloft around 10k feet mean sea level...northwest 50- 
75kt diminishing to northwest 35-50kt by 12z Monday. 


&& 


Boi watches/warnings/advisories... 
Idaho...avalanche warning in The Sawtooth Recreation Area until 730 am 
MST Monday. 
Or...none.
