Severe Weather Alert Descriptions

 Special Statement  Statement as of 12:36 PM MDT on October 30, 2014


... Winter weather arrives this weekend...

A strong Pacific storm system will move into the northwest this
weekend. Showers and a few thunderstorms will overspread central
and southeast Idaho on Saturday... with snow only at the highest
elevations. Saturday night... snow levels will fall dramatically
resulting in snow falling at the valley floors including the Snake
River Plain by Sunday morning.

Snowfall amounts will be heaviest across the northern mountains with
4 to 8 inches possible in the central mountains... and 3 to 6
inches possible in the upper snake Highlands and along the Idaho/
Montana border Saturday night and Sunday. The Snake River Plain
may see snow accumulate along the I-86/I-15 corridor Sunday
morning with around an inch possible on the valley floor and up to
3 inches on the benches. The southern Highlands can expect 3 to 5
inches in the mountains and around an inch in the valleys.

A small change in the track of the storm system could easily leave
the Snake River Plain will little precipitation... while the
situation for the mountains would likely remain unchanged.

Stay tuned for updates on this storm system. If traveling into the
mountains... especially Saturday night and Sunday... be prepared for
winter conditions.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pocatello Idaho 
127 PM MDT Thursday Oct 30 2014 


Short term...tonight through Sunday. Strong upper ridging today 
will move off to the east tonight as a strong storm system moves 
into the Pacific northwest. The strong pressure gradient between the high 
over the Dakotas and the develping low over the Pacific northwest will result 
in incrreasing southerly winds late tonight through Saturday. Winds 
are expected to become strong on Saturday...which will suppress 
precipitation over the snake plain adjacent to the southern Highlands. 
Remaining areas...especially the central mountains...will see more 
widespread precipitation. Isolated thunderstorms are possible Sat afternoon. Snow levels 
will remain high on Saturday...but fall significantly Sat evening as 
the upper low moves over Idaho. Snow levels may fall to the Snake 
River Plain floor by Sun morning. Heaviest precipitation amounts are 
expected to be in the central mountains and upper snake Highlands due 
to upslope enhancement with the southerly flow. Snow will become a 
significant issue Sat evening through Sunday. Snow amounts of 4 to 8 
inches are possible in the central mountains...and 3 to 6 inches in the 
upper snake Highlands and along the Idaho/Montana border. The Snake River 
Plain along the I-86/I-15 corridor will see snow Sun morning as the 
upper flow favors the adjacent southern Highlands. Temperatures will be 
borderline for snow...so around an inch at the valley floor and up 
to 3 inches on the benches seems reasonable at this time. Still 
more than 2 days out...and a small change in the track of the 
upper low could leave the snake plain with little precipitation. The mountains 
are more likely to remain unchanged. 


Temperatures will remain unseasonably warm through Friday...and somewhat cooler 
on Sat. Sun will be much colder. Hedges 


Long term...Sunday night through Thursday. System moving through 
the pacnw and Idaho will exit the region with lingering isolated 
rain/snow showers over the eastern Highlands Sunday night. Weak high 
pressure ridging for Monday and Monday night will be followed 
quickly by another upper level trough moving through the Idaho 
Panhandle Tuesday morning. Precipitation expected initially over the 
central mountains Tuesday morning will weaken and spread east into 
the upper snake Highlands Tuesday afternoon. Relatively flat ridging 
and zonal flow will remain in place for the remainder of the 
forecast period will limit the potential for light precipitation on 
Wednesday and Thursday to elevated terrain along the Montana border 
and to northern Custer County. Dsh 


&& 


Aviation...widespread VFR and light to moderate winds with high 
pressure ridging remaining over the region through Friday. Dsh 


&& 


Pih watches/warnings/advisories... 
none.
