Area Forecast Discussion
National Weather Service Pocatello ID
144 PM MST Sun Nov 27 2016

.SHORT TERM...Tonight through Wednesday. Next short wave moving
into the Pac NW this aftn is expected to move into ID on Mon.
Light snow will increase in areal coverage tonight and taper off
to scattered snow showers Mon eve. Heaviest snow accumulations
will be in the southeast highlands where up to 7 inches may fall
by Mon eve at higher elevations...with 1 to 3 in the valleys. The
southern highlands and the central mtns should see around 1 to 3
inches. The Snake River Plain/eastern Magic Valley about 1 to 2
inches. The complicating factor will be the wind...which is
expected to become strong Mon morn with gusts up to 45 mph by
aftn. The central mtns and upper Snake highlands should not be
quite as windy. The strong winds may compound driving difficulties
Mon...so decided to go with a winter weather advisory even though
snow amounts are expected to be below criteria.

As strong north flow aloft takes over in the wake of the short
wave...colder temps and lingering mtn snow showers can be expected
Tue and Wed. Another short wave moves into the Pac NW on Wed...
with snow increasing in coverage Wed aftn. Hedges

.LONG TERM...Wednesday night through Sunday.

A low pressure system will arrive from the northwest Wednesday night
and Thursday. This appears to be another snow maker for the region
with relatively light amounts likely. This system exits the area by
Friday. Northwest flow over the region sets up for the weekend with
some light snow possible for the mountains and upper snake highlands
as moisture streams through the region from the Pacific.

.AVIATION...A mix of vfr to ifr ceilings this afternoon as a weak
system moves through the region. A few snow showers exist as well
which may reduce ceilings and visibilities as well especially around
IDA and DIJ. Winds are rather gusty as well and will remain so into
the evening. A second system will arrive late tonight bringing more
widespread snow to the region. Expect widespread mvfr to ifr
conditions with brisk conditions redeveloping towards sunrise.
