Area Forecast Discussion
National Weather Service Great Falls MT
1102 PM MDT Tue Oct 25 2022

...Aviation Section Updated...

.SYNOPSIS...

A west to northwest flow aloft continues across the Northern Rockies
with variable clouds and few light snow showers mainly over the
mountains ending overnight. A weather disturbance moving
southeast across Idaho Wednesday will bring a period of snow
showers to Southwest Montana while much of north-central Montana
remains dry. Very windy conditions are likely across especially
north-central Montana late Wednesday night through Thursday night
with strong winds likely along the Rocky Mountain Front and areas
north of the Little Belts.

&&

.UPDATE...

Right on cue, precipitation has diminished, with winds decreasing,
as well. Inherited forecast is working well; therefore, no update is
made, at this time.
- Fogleman

&&

.DISCUSSION...

A longwave upper level trough remains in place across the Western
US and Canada with satellite imagery showing a WNW flow with
embedded moisture across the Northern Rockies and MT with a
shortwave nearing the BC/WA coast this afternoon. Another strong
North Pacific upper level jet is also noted upstream moving into
the Gulf of AK. Weak instability has continued to produce some
isolated snow showers this afternoon, mainly over the mountains,
and this should decrease fairly quickly this evening as weak upper
ridging and some mid level drying translate across the area ahead
of the wave moving inland tonight.

This system splits with the bulk of the energy moving SE across
Idaho Wednesday, bringing a period of snow or snow showers mainly to
western and SW MT. Short range models/ensembles are in good
agreement with a 3-4 hr period of showers moving through areas
mainly south of Helena and west of I-15 late Wed morning and Wed
afternoon for areas of SW MT east of I-15. Satellite imagery
indicates a fairly potent mid level cold pool with this system and
at least weak instability is likely across SW MT tomorrow afternoon.
This could lead to some brief but intense snow showers, especially
across southern portions of Madison and Gallatin counties where mid-
late afternoon timing as most favorable for convection and some
isolated lightning cannot be ruled out as well. Snow showers across
SW MT end from W to E Wed afternoon/evening as the system exits
across WY Wed night. Latest model guidance continues to limit 60% or
better probabilities for snowfall amounts in excess of one inch
Wed/Wed evening to the mountain areas in SW MT with amounts in
excess of two inches limited to the higher elevations of the
Beaverhead, Madison and Centennial ranges.

The previously mentioned upper level system/jet currently moving
into he Gulf of AK will move into western Canada Wednesday night
with a belt fast westerly flow aloft sagging south into the Northern
Rockies and MT late Wednesday night through Thursday night.
50-60kt 700MB flow develops late Wednesday night across the
Glacier Park/Rocky Mtn Front areas and expands across western
portions of N-central MT by Thursday afternoon. A strong surface
pressure gradient across the Rockies and favorable temp/wind
profiles above ridgetops support strong wind gusts (in excess of
60kts) along the Rocky Mtn front and across much of Glacier
county late Wed night through Thursday with latest ensemble
guidance maintaining likely (60-70%) probabilities for wind gusts
in excess of 48kts across Cascade county Thurs/Thurs night. A high
wind watch continues for these areas with some potential for
expansion to Judith Basin county and areas near the Bears Paw,
though probabilistic guidance does not support higher winds in
those areas at this time.

Upper level jet moves off to the east late Friday with winds aloft
relaxing and a period of less windy and dry conditions following
through early Sunday. Temperatures look to warm back to near and
slightly above climatological averages Friday through early next
week with most locations seeing afternoon temperatures in the 50s to
near 60 by Sunday. Longer range multi-model ensembles are in general
agreement to bring a larger scale trough back into western Canada
late this weekend with deeper troughing developing next week across
the western US. This will initially bring an increase in winds as
flow aloft re-intensifies late this weekend into early next week
with probabilistic guidance indicating a high chance (>50%) for
gusts in excess of 48kts late Sunday and Monday (Halloween) across
western and SW portions of north-central MT. While the amplifying
trough next week is largely supported by long range models, details
in strength/timing are still less certain, however a turn back to
below average temperatures with increasing potential for
precipitation/snow appears likely by the middle of next week.

.AVIATION...
1102 PM MDT Tue Oct 25 2022 (26/06Z TAF period)

Continued mountain obscuration is expected through the entire
2606/2706 TAF period as Pacific moisture streams eastward within an
overall zonal flow pattern. A weak disturbance moving within this
pattern will bring another round of mountain snow and valley/plain
rain/snow to areas southwest of a KCTB, to KGTF, to KLVM line from
approximately 12z Wednesday to 03z Thursday. While a rogue
snow/rain shower can't be ruled out at the KHLN, KBZN, and KEKS
terminals over this timeframe, confidence remains too low to mention
any prevailing groups. VFR conditions are predominately expected
across the Northern Rockies over the next 24 hours, with the
exception of beneath areas of precipitation where MVFR conditions
will occur. - Moldan

KWYS TAF will not be issued again until airport operations resume
next spring.
