NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
316 am MST Friday Nov 28 2014 


Short term...today through Sunday...SW flow aloft ahead of an 
incoming cold short wave will continue the pattern of middle and 
high level moisture streaming across the area today. Rain and snow 
will increase in most areas today...especially in the north. The 
snow level will be slowly falling today...but place like McCall... 
where rain has been falling all morning...will not change over to 
snow until late tonight. Temperatures will remain mild today...averaging 
10 to 15 degrees above normal. Tonight...precipitation will continue in 
most areas...especially the north...as snow levels gradually fall 
in advance of the short wave. Saturday...a sharp cold front will 
move through from northwest to southeast. This will enter Baker County in the 
morning...reach the Boise area in the afternoon...and get to the 
western Magic Valley by midnight. This will be a significant cold 
front...with temperatures dropping sharply behind. Precipitation 
will increase in the Snake River Valley Saturday...with most of 
the precipitation falling as rain before the front moves through. There 
may be a brief period of snow after the front passes...but frontal 
passage should signal the end of the notable precipitation. Throughout 
these first two days...precipitation in the mountains will be heavy. 
Locations above around 7000 feet could see over a foot of snow. 
Places like McCall...at 5000 feet...will see several inches of wet 
heavy snow. At this time...it appears that Road temperatures will prevent 
the snow from causing significant travel problems in the populated 
areas...so no Snow Advisory will be issued. However...if you plan 
on traveling over the higher passes...be prepared for heavy snow 
and snow-packed roads through the weekend. 


Saturday night the cold air will pour into the region behind the 
departing cold front. There will be significant drying and precipitation 
will decrease. On Sunday...the precipitation will taper off to showers... 
and these will be found mainly in the south and east. Highs Sunday 
will be 10 to 20 degrees colder than Saturday. Winds that will be 
gusty Saturday night behind the cold front will diminish by Sunday 
afternoon. 


Long term...Sunday night through Thursday...warm front 
associated with a moist Pacific low pressure system approaching 
the California coast lifts north across the forecast area on 
Monday. 00z GFS/06z NAM have the fastest timing of the frontal 
passage...reaching McCall/Baker City around 18z Monday. 00z European model (ecmwf) 
is about 6 hours slower. All guidance suggests the cold air will 
mix out of most of the Treasure valley by the afternoon with 
increased southeasterly winds. The warm frontal passage will 
initially be dry as it moves northward through the dry Arctic 
airmass. Moisture will increase along the front as the upper low 
reaches the California coast and moisture is advected northeastward. 
There is uncertainty regarding timing of the returning Pacific 
moisture so have left probability of precipitation higher across much of the County Warning Area Monday. 
The County Warning Area remains in the warm sector of the Pacific low off the California 
coast through early Wednesday which will bring periods of 
widespread precipitation. The low weakens as it moves inland late 
Wednesday leaving moist westerly flow over the intermountain west. 
Temperatures...below normal on Monday...will warm quickly and 
remain above or near normal Tuesday through Thursday. 


&& 


Aviation...mostly VFR conditions with middle-high clouds today. MVFR 
conditions and mountain obscuration in the west central mountains 
from rain and snow showers through early afternoon. Rain will 
push south this afternoon...mainly north of a kbno-kono-ksnt 
line...for MVFR conditions. Surface winds generally light. Winds 
aloft near 10k feet mean sea level...west at 35 to 45 kts. 


Weekend outlook...Saturday...an Arctic front will push south for 
MVFR rain changing to IFR snow in the mountains. Otherwise expect 
VFR conditions for most of southeast Oregon and southwest Idaho. 
Saturday afternoon valley rain and mountain snow will spread south 
to the Nevada line and continue across the entire area through late 
Saturday night...with snow levels lowering to the valley floors. 
Sunday drier air moving down from the north will bring improving 
conditions...with mainly VFR.
