.DISCUSSION...
/Issued 222 PM MST Wed Jan 14 2026/

 - Meteorological Overview:

H500 ridge over the Northern Rockies today will shift westward and
back over the western seaboard by Thursday as a shortwave over the
Gulf of Alaska crests the ridge axis in Northern BC/Alberta and digs
southeast over the Northern High Plains through Thursday night. At
the surface a cold front will dive south and through North Central
Montana during the mid- to late morning hours and Central and
Southwest Montana during the afternoon hours on Thursday. This front
will bring cooler, near normal, temperatures to all locations for
the day on Friday, along with a period of strong and gusty north
winds to areas east of the I-15 corridor over the plains of Central
and North Central Montana. Additionally, a period of light rain/snow
mix or snow is possible along the southward advancing front, most
notably in the northerly upslope areas of Central Montana, but any
accumulations will be minor.

Temperatures will begin to moderate across Southwest through North
Central Montana through the weekend and early next week as upper
level ridging amplifies over the western seaboard and predominately
dry, northwest flow resides over the Northern Rockies. - Moldan

 - Forecast Confidence & Scenarios:

High Winds Thursday and Thursday night...

Climate anomaly indicators such as the NAEFS and ECMWF EFIs continue
to support to the potential for a climatologically unusual wind
event from the afternoon hours on Thursday through Friday morning in
wake of a southward advancing cold front, generally along and
northeast of a line from Judith Gap to the Sweet Grass Hills. H850
winds per NAEFS analysis are prog`d to reach between 35-45kts, which
combined with strong pressure rises and cold air advection in wake
of the aforementioned front could lead to the transport of these low
level winds to the surface. NBM probabilities for wind gusts in
excess of 48kts continue to run/have increased to in excess of a 70%
chance on the downwind/downsloping side of the Island Ranges (i.e.
Sweet Grass Hills, Bears Paw, Highwoods, Judith, and Snowy) of
Central and North Central Montana, along with extreme northeastern
portions of Northern Blaine County.

A High Wind Watch remains in effect for the Bears Paw Mountains and
Southern Blaine, Fergus County below 4500ft, and Northern Blaine
County from Thursday afternoon through late Thursday night given the
potential for strong north winds; with additional High Wind Watches
now in effect from Thursday afternoon through Thursday night for
Eastern Toole and Liberty Counties, Hill County, and Judith Basin
County and Judith Gap. Areas that will see the strongest north winds
through these timeframe will once again be in lee of the Island
Ranges, along with any terrain gaps where the the north winds will
be funneled through and subsequently enhanced. - Moldan

15/00Z TAF Period
