NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
825 PM MST Friday Dec 19 2014 


Discussion... 
lingering showers moving across southwest Idaho this evening as 
the upper trough and shortwave exit the area. This handled in the 
current package so not planning any updates to the forecast 
package at this time. 


Focus turns to the next system thats poised to move into the 
region bringing copious amts of precipitation to the area this 
weekend. Water vapor satellite loop shows a moist connection 
extending back into the western Pacific. Strong warm air 
advection moves into the region starting late Saturday and through 
midnight. Snow levels rise rapidly...so biggest concern is how 
high are they expected to go and therefore the snow amounts. Agree 
with what the latest model runs are indicating with potentially 
higher snow levels than whats in the current forecast...which 
would also change snow totals and the current Snow Advisory out 
for the west central mountains and Camas Prairie. Will let the 
midshift do and large scale changes to the forecast if needed. 


&& 


Aviation... 
isolated MVFR rain and snow showers across SW Idaho this 
evening will diminish by 06z. Snow above 4500 feet mean sea level. Areas of MVFR 
snow...and rain below 5000 feet mean sea level...will spread into Harney/Baker 
counties after 06z...then across most of southeast Oregon and 
southwest Idaho after 12z. After 18z...expect widespread MVFR and 
local IFR conditions. Snow levels near 4500 feet mean sea level Saturday morning 
will slowly increase reaching 8000 feet across southeast Oregon and 5000 
feet near McCall Saturday night. Expect snow to switch to rain by 
06z Sunday at kmyl remain as all rain thereafter. Mostly MVFR rain 
will continue through Sunday. Light surface winds. Winds 
aloft...southwest 15-25 kts up through 10k feet mean sea level. 


&& 


Previous discussion... 
short term...tonight through Sunday...a very strong and wet 
winter storm is on its way into the region tomorrow through 
Sunday. A Winter Weather Advisory has been issued for the west- 
central and Boise Mountains and Camas Prairie. See the advisory for 
details on timing and snow amounts. Snow levels will initially be 
around 4000 feet...but will rise rapidly Saturday night into early 
Sunday as a warm front pushes into the region from the southwest. 
Snow levels near McCall will be very close to the ground Sunday 
morning into Sunday afternoon...leading to considerable 
uncertainty on final snow totals. At this point...we are going 
with a forecast that changes it to a mix Sunday morning...which 
significantly limits the snow that would occur should it remain 
all snow through Sunday. The current forecast of around 9 inches 
in McCall by midday Sunday could end up being closer to 15 inches 
should it remain all snow. Elsewhere...no snow is expected in the 
Treasure valley. Rainfall will likely increase middle-afternoon 
Saturday and the heaviest rain is expect to last into the evening. As 
snow levels rise Saturday night into Sunday morning...even places 
like Bogus Basin will change over to rain and remain all rain 
Sunday afternoon. Temperatures will stay above normal through the short 
term. Winds will be light for most areas. However...ridges above 
around 6000 feet in eastern Oregon and above 7000 feet in SW Idaho 
will see gusts to 40 miles per hour Saturday night and early Sunday. Rainfall 
amounts will be high even in lower elevations. Totals in the short 
term will range from a half inch to one inch in the valleys...with 
totals...or liquid equivalent amounts...of one to two and a half 
inches in the mountains. There are no concerns with river flooding 
owing to the present capacity available in the river systems. 


Long term...Sunday night through Friday...Sunday night 
widespread rain and snow will continue over the mountains but 
decrease to scattered showers in the valleys...with snow levels 
ranging from 5000 feet in the north to 8000 feet in the south. On 
Monday showers will decrease in coverage with only light amounts 
under drier more northerly upper level flow ahead of a building 
ridge. Models all show the ridge shifting inland over the 
intermountain region on Tuesday...then weakening on Wednesday ahead 
of the next Pacific weather system. Precipitation will be confined 
mainly over our northern mountains Monday night through Tuesday 
night...then spread across most of our County Warning Area on Wednesday. Snow levels 
on Wednesday will range from about 4500 feet over the mountains of 
Baker County Oregon and central Idaho up to 7000 feet along the 
Nevada border. Temperatures will remain 10 to 15 degrees above 
average. 


Wednesday night through Friday...a cold moist shortwave will affect 
our region beginning Wednesday night into Christmas morning. Most of 
the precipitation will taper off by Christmas afternoon except for 
higher elevations. There is some uncertainty about what form the 
precipitation will take as model runs have been inconsistent. 
Currently it looks like snow levels may not fall below 3000 feet until 
the bulk of precipitation has passed. Temperatures will decrease to 
near normal with the passing shortwave. Cold temperatures and a 
chance of precipitation in the mountains will continue through 
Friday.
