NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
927 am MST sun Dec 21 2014 


Discussion...rain and snow continue in Idaho zones north of the 
snake basin this morning but it has decreased in Oregon and southwestern 
Idaho. More precipitation upstream which models bring in middle-day through 
tonight. Snow changed to rain at McCall around 330 am MST and 
our entire County Warning Area below 6000 feet will have rain rather than snow 
through mid-afternoon. Snow level will slowly lower ths afternoon 
and tonight as upper winds change from westerly to northwesterly. Temperatures 
will cool down with highs Monday about 10f lower than today. Wind 
Advisory will continue in our southern zones through the day. 12z boi 
radiosonde observation had very strong westerly winds aloft. Avalanche warning 
still in effect in The Sawtooth Recreation Area through at least 
700 am Monday. General trend throughout our County Warning Area is cooler and 
drier tonight through Monday. Dry through Wednesday then colder 
with a chance of snow Wednesday night. Chance of light snow c 
ristmas day...then dry and cold through Saturday. No updates at 
this time. 


&& 


Aviation...widespread MVFR-IFR conditions with precipitation. 
Mountains obscured. Snow levels at the surface in central Idaho 
mountains ranging up to 10k feet mean sea level SW of the Snake River Plain. 
Snow levels will slowly fall from north to south as precipitation 
band moves southward today and tonight. VFR conditions south and 
west of a line from kbno-kreo in southeast Oregon. Surface winds westerly 
15-25kt with gusts to 45kt this afternoon in southeast Oregon and eastern 
Magic Valley east of kjer...northwesterly surface winds up to 15kt 
elsewhere. Winds aloft around 10k feet mean sea level...northwest 50-75kt diminishing to 
northwest 35-50kt by 12z Monday. 


&& 


Previous discussion... 
short term...today through Monday...the warm front is finally 
showing signs of punching northward as the models have promised. 
Bogus Basin is above freezing and the web cam indicates rain. Kmyl 
is still snowing...but should change to rain shortly. The west-southwest will 
be allowed to expire at 3 am with the morning forecast package. 
Light to moderate rain is still falling over most of the region... 
and we expect it to continue for much of today as a warm moist 
flow remains entrenched aloft. Latest hrrr model indicates a break 
this morning in the lower Treasure valley and western portions of 
the upper Treasure valley...including Boise. But then precipitation 
spreads back into these areas this afternoon. This will have a 
strong impact on temperatures today. We have lowered the forecast 
for these areas due to high-resolution model data indicating 
less warming than previously expected today. As we move into 
tonight...snow levels move back down and moisture will finally 
begin to decrease. The chance of precipitation decreases sharply Monday 
and temperatures will cool further. Winds will be strong today in southeast 
Oregon...the southwest Highlands of Idaho...and the higher terrain 
of southern Twin Falls County. The Wind Advisory is still on track to go 
into effect at 8 am MST and run until 5 PM MST. 


Long term...Monday night through Saturday...conditions are 
expected to continue to dry out Monday night and Tuesday as a 
ridge off of the California coast amplifies. This will keep 
temperatures above normal. Models are in good agreement of the 
ridge starting to flatten out on Wednesday ahead of a trough 
moving in from coastal British Columbia. The latest GFS and European model (ecmwf) 
runs have begun to agree on timing of this trough and associated 
cold front. Precipitation chances will spread from northwest to southeast late Wednesday 
night with snow levels around 5000 feet dropping to 2000 feet by 
early Christmas morning. However...this system will likely move 
out of the area quite quickly so conditions should dry out once 
again Christmas afternoon/evening. The associated cold front will 
bring temperatures back to near normal for the rest of the period. 
A cooler northwest flow will set in for Friday and beyond.
