NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pocatello Idaho 
328 am MST Monday Dec 29 2014 


Short term...today through Wednesday. A broad area of low 
pressure remains entrenched across the region this morning. There 
are several weak disturbances embedded in this pattern...leading 
to pockets of very light snow or flurries across eastern Idaho. 
This especially the case where we have low/middle clouds and getting 
the seeder feeder process going. We also have some breaks in the 
clouds as well. For the rest of the day...expect more of the same 
with light snow painted throughout eastern Idaho. It is really 
hard to pinpoint where we might see pockets of enhanced snowfall 
more than a handful of hours out...so we opted with a broad 
approach to the forecast. If we get enhanced snowfall in 
spots...there could be around an inch of new fluffy snow. 
Otherwise...expect nothing more than a dusting. Temperatures will 
continue to trend colder today...and in some spots we have likely 
see highs for the day. As the pattern shifts south and a dominant 
storm develops across Utah and Nevada....we will see clouds and 
snowfall quickly ending tonight and north/northeast flow 
developing. This will help bring colder air to eastern Idaho along 
with stronger winds in many areas. This will drop lows tonight 
into 0-10 degree range for the southwest half of the forecast 
area. The rest of US will be below zero...with temperatures colder than 
-20 along the Montana border and also the higher valleys of the 
central mountains. With winds picking up...wind chills will be 
below zero for everybody. In many places...values will be -20 to 
-40. Where we have the low wind chills combined with 10+mph 
winds...we have issued wind chill warnings for this evening 
through Tuesday morning. Even where we don't have wind chill 
warnings and they are going to be at -20 or colder...the same 
impacts will be there in terms of quick onset of frostbite and 
hypothermia. 


Cold temperatures will be with US through midweek as high pressure 
builds over Idaho and we keep a northerly flow. Because of the 
cold start tomorrow...highs in the single digits and teens are 
forecast. We wouldn't be surprised if some places don't get above 
zero. Tuesday night will be even colder as winds relax and the 
Arctic air is in place. Right now...it appears any high clouds 
moving over the state will not have any effects on keeping 
temperatures a bit warmer. Lows of -10 to -30 are forecast except 
for the Magic Valley and south Central Highlands...but still 
expect those areas to be below zero. Wind chills will be dangerous 
low again and likely in more areas versus tonight. By 
Wednesday...we will see middle and upper slopes warming a bit. Most 
valleys will stay cold due to inversions and a colder start. Those 
areas will only reach the single digits and perhaps low teens. 
Above the inversion...we may places in the upper teens for highs. Keyes 


Long term...Thursday night through Sunday. 
GFS looks to be following the European models with the closed low 
over Southern California and Arizona Wednesday/Thursday...followed 
by a flattening of the ridge in the eastern Pacific Friday through 
Sunday. Dry air is expected over southeast Idaho Wednesday and 
Thursday with lingering cold temperatures. Temperatures begin to 
modify warmer with more westerly flow...increasing cloud cover and a 
chance of precipitation mainly over the mountains and along the 
Montana and Idaho border. Precipitation in the central mountains and 
eastern Highlands could become more significant around Sunday if 
deeper moisture off the Pacific arrives like the GFS suggests. Receiver station 


&& 


Aviation...the main problem is low stratus in the snake plain 
persisting over kida...kpih and kbyi. With the trough moving 
southward today the 700 mb winds becoming easterly which will help 
transport the status down valley to the west. We should see some 
lifting of the ceilings to around 3000 feet above ground level at kida/kpih by 
18z...then a gradual clearing after midnight. Kpih/kbyi may take 
until Tuesday morning to clear. Snow should favor the mountains 
where orographic lift is available. Some temporary wind convergence 
in the snake plain could support some light snow...but it is really 
hard to count on for timing. For ksun...will be watching 
southeasterly surface winds this afternoon and looking for low 
stratus to be drawn into the the Airport area. Receiver station
