Severe Weather Alert Descriptions

 Special Statement  Statement as of 2:36 PM MST on February 12, 2016


... Snow and wind to impact travel this weekend into Monday...

A series of storm systems will bring wintry weather to the region
this weekend into Monday. The first storm will bring a round of
light snow to the central mountains and Montana and Wyoming
Highland border regions on Saturday with light snow
accumulations. A second storm will bring a prolonged period of
snow to the central mountains and upper snake and eastern
Highlands Sunday into Monday. Snow accumulations Sunday and Monday
are expected to range from 2 to 5 inches in Highland valleys with
5 to 10 inches at pass level. Snow accumulations along the
Interstate corridor are expected to range from a trace around
Burley to up to an inch from Idaho Falls to the Montana border. In
addition... strong southwest winds Sunday and Monday with gusts up
to 40 mph will create difficult travel for high profile vehicles
and areas of blowing and drifting snow for passes such as Galena
Summit... Pine Creek Pass and Teton Pass.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pocatello Idaho 
915 PM MST Friday Feb 12 2016 


Short term...tonight through Monday night. A quick update this 
evening to correct an errant weather grid. Otherwise...everything 
looks to be on track as the next Pacific storm system is advancing 
into/through western Washington/Oregon at this time. See previous 
discussion below. Huston 


An upper level ridge is currently in place across southeast 
Idaho...maintaining dry weather and above normal temperatures above 
valley inversions. This ridge will quickly retreat eastward 
overnight as a quick-moving disturbance slides eastward across the 
northern rockies late tonight and Saturday. As a result...a gradual 
increase in snow shower activity will be found across the central 
mountains and Montana and Wyoming border Highland areas on 
Saturday...with amounts generally an inch or less. A second wave 
will provide a more substantial increase in snow shower activity for 
Sunday...as this second system will have the benefit of a greater 
supply of attendant moisture. The central mountains and upper 
snake/eastern Highlands will receive the most snowfall with this 
activity and for these areas snowfall is expected to be falling 
through the day Sunday. Snowfall will quickly taper off as one 
descends down in elevation towards the snake plain and eastern Magic 
Valley where rain and rain/snow showers are anticipated. Snowfall 
accumulations along the Interstate corridor on Sunday are expected 
to range from a trace in the Burley area to closer to one inch from 
Idaho Falls to the Montana border with higher amounts towards Monida 
Pass. Snow accumulations for the eastern Highlands Sunday are 
expected to be in the 2 to 5 inch range...with northwest slopes 
favored. Slightly less snowfall for the central mountains. Winds 
will be another impact associated with this system. Southwest winds 
will increase into the 20 to 30 miles per hour range with higher gusts by 
Sunday afternoon...creating some difficult travel for high profile 
vehicles. This wind will also likely create areas of blowing 
snow...particularly at pass level. 


Moist northwest flow is expected to persist Sunday night and 
through Monday...with snow showers continuing particularly across 
the eastern Highlands and Wyoming border region. Winds will remain 
elevated with the potential for blowing snow at pass level to 
continue. Additional accumulations Monday are expected to be 
similar to those on Sunday. A Winter Weather Advisory may be 
required for the eastern Highlands as the event draws nearer to 
highlight potential impacts...as travel and recreation will 
be negatively impacted on Sunday and Monday. Ad/hedges 


Long term...Tuesday through Friday. Upper ridge shows signs of 
shifting east Tuesday per GFS and European model (ecmwf). GFS ensemble members having 
a hard time with evolution of upstream trough/cutoff low in the east 
Pacific. European model (ecmwf) favors a deeper low than operational GFS...which 
maintains a more progressive...open trough. Despite the uncertainty 
of upper-level features the timing of onset of precipitation is 
virtually the same...which is Wednesday night. GFS...being the more 
progressive of the 12z runs...ends most of the precipitation with the 
passage of the 500mb trough late Thursday night whereas the European model (ecmwf) 
depicts the upper low lifting across California and into Idaho 
around that same time period...and thus keeps wet conditions over 
the region through about Friday morning. Temperatures continue to look 
warmer than normal through most of the week. Hinsberger 
&& 


Aviation...with upper ridging shifting to the east today and no 
widespread fog/stratus field over the snake plain...expect VFR 
conditions at the terminals through the period. Models bring through 
a middle and upper cloud ceiling in the overnight hours with southerly 
winds increasing near sunrise tomorrow. Conditions should inhibit 
fog/stratus development tomorrow morning. Hinsberger 
&& 


Pih watches/warnings/advisories... 
none.
