Area Forecast Discussion
National Weather Service Pocatello ID
1026 AM MST Thu Dec 22 2016

.UPDATE...

Minor update to the forecast to lift the fog advisory and to touch
up sky forecast for today into tonight.

Valle

&&

.PREV DISCUSSION... /issued 535 AM MST Thu Dec 22 2016/

UPDATE...Fog has really thinned out across the Upper Plain thanks
to northerly winds. We've canceled the Dense Fog Advisory there
and left it in place for the Lower Plain, although the worst
appears to be only from Fort Hall through American Falls.  Keyes

PREV DISCUSSION... /issued 308 AM MST Thu Dec 22 2016/

SHORT TERM...Today through Christmas Eve Day. First things
first. We continue with low clouds and areas of freezing fog (in
some areas below 1/4mi) in some valley locations. The bulk of it
is across the Snake Plain and adjacent valleys along the
Interstate Corridor. We might be losing some of that toward Idaho
Falls & Rexburg as northerly winds kicked in, but it appears to be
sloshing south and west at the same time. We extended the Dense
Fog Advisory into the Lower Plain and out through 10am. We should
low clouds and fog dissipate through the day, leaving us with
another chilly afternoon. We undercut the numbers in many areas
based on trends from yesterday and this morning, counting on
inversions holding. For tonight, we will see some higher clouds
move in from the west which MAY keep fog at bay. However, I think
we will see some patches of stratus reform.

Tomorrow afternoon begins a rather stormy period that lasts all
the way through Christmas. The models are still not 100% in sync
but are fairly close on bringing in snow during the afternoon across
the central mountains, extending also into the Lava Beds around
Shoshone northeast to near Monida Pass. Moisture will really
increase tomorrow night and early Saturday. All of the models
again are fairly similar on this trend. Due to the flow coming
from the south, we are looking at more persistent moisture falling
in the southern highlands, as well as from Hailey/Sun Valley
through Lone Pine. This includes the Shoshone Lava Beds, Arco
Desert and Upper Snake Highlands closer to the Divide. This is due
a favorable upslope pattern which looks to be quite strong. On the
flip side, several areas will see downslope conditions. This
includes the Challis area, the valleys along the Interstate
Corridor from Burley to Blackfoot, around Palisades and Driggs. In
fact, temperatures will be likely hover around/just above freezing
in those areas which may actually play havoc with precipitation
type. It may end up wet snow or just plain rain at times with not
much potential for freezing rain/sleet at the moment. This
obviously will cut down on snow amounts. The models get out of
sync by a wider margin on Christmas Eve Day. With the pattern
splitting, the models aren't quite sure what will be left to
affect eastern Idaho. We tried to not make any sweeping changes
based on that and left the previous "broadbrush" approach to the
forecast. We will definitely be tweaking things as we get closer
to Saturday. The pattern still looks like it will be warm enough
for a mix or changeover to rain across portions of the Snake Plain
and southern mountain valleys. The cold front should swing through
during the day, which may enhance rain or snow as it sweeps
across. It still looks breezy at times which will likely create
pockets of blowing and drifting. Needless to say, the Winter Storm
Watches are still in effect even with some changes to snowfall
totals.  Keyes

LONG TERM...Saturday night through Thursday. Models remain close
with upper low closed off over northern Nevada and shifting east
toward Utah by Christmas morning. Cold front expected to be through
E Idaho at this time, with snow levels dropping back to valley
floors. Question will be how much precipitation will remain across
the region at this time. Models keep band of snow mainly over
eastern half of forecast area ahead of 500mb trough axis. As trough
axis shifts east on Christmas day, flow turns either northwest in
GFS or is heavily influenced by wrap around in ECMWF, so expect
continued snow across the region during the day. Expect travel
conditions to remain impacted with several additional inches of
snow through Christmas day. Weak shortwave feature drops through
panhandle Christmas night, reinforcing threat for light snows
through the night mainly across eastern highlands region, but
accumulations significantly taper off. Much drier conditions
expected for Monday and Monday night. Next fast moving system
drops into the PacNW states Monday night, reaching Idaho by
Tuesday. Snow associated with this system Tuesday and Wednesday
appears to remain generally focused over higher elevations with
much of the Snake Plain shadowed by northwest flow. Currently,
models are indicating next ridge to build into the region by
Thursday with return to drier conditions. DMH

AVIATION...Satellite imagery shows region of low stratus/fog
extending through the Magic Valley up the interstate corridors
through Pocatello toward Idaho Falls, and through lower elevations
south toward Utah. Light north winds have begun to erode the north
extent of the moisture. Believe the IFR/LIFR conditions will be
difficult to erode through the day at KBYI/KPIH although some
improvement will be possible this afternoon. Regardless, conditions
should deteriorate quickly again with return to poor ceilings/vis
overnight tonight. With KIDA and KDIJ currently out of the
stratus/fog layer, expect them both to remain MVFR through the day
though could see a slosh back to LIFR briefly around sunrise. Again
with these two sites, very good chance to see both of them also
return to IFR/LIFR overnight tonight. KSUN expected to remain VFR
throughout the period. DMH
