Area Forecast Discussion
National Weather Service Great Falls MT
1130 PM MDT Sun Oct 2 2016

Aviation Section Updated

.DISCUSSION...

ADDITIONAL UPDATE TO HIGHLIGHTS...Have made some additions to the
winter weather highlighted areas. Forecast snow amounts above 6500
feet in Central/Southern Lewis and Clark County, as well as in
Broadwater County, seem to warrant inclusion in the Advisory. Have
also added above 6500 feet in the Little Snowy Mountains in southern
Fergus County, and above 4000 feet in the northern slopes of the
Highwood, Bears Paw, and Little Rocky Mountains due to enhanced
snowfall from the expected northerly low/mid level flow. Changes
were also made to have elevations specifically mentioned in the
headlines of the statement. No changes to forecast snow amounts at
this time. Sorry for any inconvenience with this late
adjustment. Coulston

Only adjustments to the forecast this evening is to keep mention
of showery precipitation in through midnight and focus it east of
a Dillon to Havre line. Will also keep mention of isolated
thunderstorms through midnight on the southeast TFX border -
basically, from Monida Pass northeast through Bozeman and
Lewistown. Precipitation should become more widespread and
stratiform in nature after midnight. Temperatures and wind appear
to be on track, so have not changed them. Forecast models are in
the process of being updated, so will not make any changes to the
current winter weather highlights. However, will update the
statements to fine tune snow amount wording.
Coulston

.AVIATION...
Updated 0600Z.
Mid-to upper-level low centered over west-central OR will move
generally east-northeastward and should reach east-central MT around
06Z/Tue. Accordingly, widespread light to moderate rain is expected
at lower elevations, while mountain snow is expected near and
especially above 5000 feet MSL. However, rain may mix with snow
after 00Z/Tue east of a KHVR to KDLN line after 00Z/Tue. Widespread
mountain obscuration is also expected. Widespread VFR or MVFR is
expected to deteriorate to primarily IFR toward and especially after
12Z Mon. Also, occasional LIFR are possible after 12Z Mon. Jaszka

.PREV DISCUSSION...
/ISSUED 540 PM MDT Sun Oct 2 2016/

Tonight through Tuesday...Water vapor shows a deep low pressure trof
over the West Coast with a disturbance moving through the southwest
flow aloft over Central and Southwest Montana. Another disturbance
is rotating around the base of the trof and moving over Nevada. This
will be approaching Southwest Montana tonight and moving across the
zones. Isolated thunderstorms are possible over the southwest zones
this evening but instability over the extreme southwest zones will
decrease rapidly towards sundown. The air mass will then generally
remain stable through Tuesday. The low pressure trof will move east
during the period but the strongest dynamics should remain south of
the state as the upper level jet pushes across Wyoming. Montana be
under a broad area of diffluent flow aloft, however, and periods of
widespread precipitation are likely through Tuesday. The main
concern will be snow amounts, and, along with the amount of moisture
available, snow levels will become very important as the low
approaches.  Monday night the air mass will cool significantly and
lowest snow levels during the period will develop along and east of
a Havre to Lewistown line. However, most snow will remain above 4000
feet in this area. Low levels will be drying from the west Tuesday,
first across the Northern Rockies, and these drier conditions will
spread east during the day. However, north to northwest flow will
continue and low levels to the east will remain quite moist. The
winter weather advisories and watches issued are all concerned with
snow accumulations at higher elevations. At lower elevations,
slippery road conditions are the main concern. Zelzer

Tuesday Night through Sunday...Not many changes made to the forecast
this afternoon. Scattered showers linger over much of the CWA
Tuesday night and Wednesday...with the best chances across the
western and southwestern mountains...as a weakening shortwave
disturbance is drawn in behind the departing storm system. Cold air
behind this system could continue low snow levels around 4000-6000
feet across central and southern portions...with snow levels further
lowering to close to 3000 feet across the north. This could bring
some light snow mixing in across portions of the Hi-Line and along
the Rocky Mountain Front Wednesday into Wednesday night...possibly
lingering into Thursday. Snow amounts across the high plains are
expected to be low at this point...with the main impacts being those
that occur with the first snowfall of the year. An unsettled
westerly flow develops for the second half of the week and on
through the weekend. Several weak systems will move through this
westerly flow, but timing varies widely among the suite of model
solutions. Therefore, cannot do much better than a general model
blend for the extended period, maintaining slight chances for rain
and mountain snow showers with temperatures gradually warming back
to near seasonal averages in the 50s to low 60s. Snow levels should
also raise through the long term..perhaps becoming above 8000 feet
by the weekend...as these next disturbances is not expected to have
as much cold air. PN/Anglin
