.KEY MESSAGES...

 - On Wednesday there will be showers and thunderstorms around
   with gusty to strong winds.

 - It be warm through Wednesday with a cool down Thursday through
   Saturday.

 - It will be windy across Southwestern Montana on Wednesday and
   across North-central Montana on Thursday.

.DISCUSSION...
/Issued 239 PM MDT Tue May 12 2026/

 - Meteorological Overview:

This afternoon there is an upper-level ridge over North-central,
Central, and Southwestern Montana. This will allow temperatures to
warm up with mostly dry weather. On Wednesday the upper-level ridge
remains over North-central, Central, and Southwestern Montana
with an upper-level trough approaching the area. This upper-level
trough is associated with a Pacific cold front. On Wednesday due
to southerly flow aloft and the upper-level ridge it will be hot.
Due to the approaching upper-level trough combined with an
increasing pressure gradient it will be windy on Wednesday in
Southwestern Montana. Due to increasing moisture combined with
warm air advection due to southerly flow aloft instability will
build across North-central, Central, and Southwestern Montana.
This will bring scattered showers and thunderstorms to the area.
The primarily risk with any thunderstorm will be strong winds and
lightning. Wednesday evening/night the upper-level trough and cold
front begin to move through the area. Due to a strong pressure
gradient and strong low and mid-level winds there will be windy
conditions across North-central Montana Wednesday evening into
Wednesday night. On Thursday the upper-level trough remains over
North-central, Central, and Southwestern Montana. On Thursday
there remains a strong pressure gradient. This combined with
strong low and mid-level winds will bring windy conditions to
North-central Montana. On Thursday due to cold temperatures aloft
and at the surface there will be snow at some mountain locations.

Friday through Sunday upper-level troughing remains present with a
few shortwaves moving through the upper-level flow. This will keep
cooler temperatures around with isolated showers and thunderstorms
at times Friday through Sunday. -IG

 - Forecast Confidence & Scenarios:

On Wednesday the Storm Prediction Center (SPC) has issued a Slight
Risk (15% chance for wind gusts of 58 mph or greater within 25 miles
of a point) for severe weather across a portion of North-central
Montana. Additionally across the rest of North-central, Central, and
Southwestern Montana the SPC has issued a Marginal Risk (5% chance
for wind gusts of 58 mph or greater within 25 miles of a point) for
severe weather. There is a 15 - 25% chance for thunderstorms across
North-central, Central, and Southwestern Montana.

On Wednesday there is a 40 - 80% chance for wind gusts of 55 mph or
greater. Some of those wind gusts will be from thunderstorms while
some will be driven by the low and mid-level winds. As a result for
Wednesday afternoon a High Wind Watch was issued for Southwestern
Montana. On Thursday there is greater than an 80% chance for wind
gusts of 55 mph or greater across most of North-central Montana. On
Thursday there is an 80% chance for wind gusts of 75 mph or greater
along the Rocky Mountain Front. As a result a High Wind Watch
remains in effect for most of North-central Montana for Thursday. On
Thursday across lower-elevations of Glacier National Park there is a
20 - 40% chance for 2 inches of snow or greater. -IG

.AVIATION...
13/00Z TAF Period

VFR conditions will prevail through the start of the period with
increasing cloud cover overnight ahead of a storm system passing
through on Wednesday. Winds will be generally light overnight but
pick up out of the west/southwest after 13/18Z with widespread
gusts up to 35kts possible through the remainder of the TAF period.
The strongest winds will be found along the Rocky Mountain Front
and across Southwest Montana where gusts up to 50kts are possible
at times.

By 13/20Z, isolated to scattered showers and thunderstorms start
form across the region generally moving southwest to northeast
across the region. The main concerns will be lightning and gusty,
erratic winds. CIGs will generally prevail VFR towards the end of
the TAF period but high MVFR CIGs are possible, particularly
across Southwest Montana.  -thor

.FIRE WEATHER...

UPDATE: FWZ113 and Southwest Montana have been upgraded to a Red
Flag Warning for Wednesday.

Elevated to critical fire weather conditions are expected on
Wednesday as temperatures soar well above normal and into the mid-
80s to low 90s, with the potential for numerous locations to set new
daily record highs for May 13th across Southwest through North
Central Montana. The warm temperatures will be accompanied by dry
conditions, with relative humidity values in the teens across much
of the lower elevations of North-Central, Central, and Southwest
Montana.

Strong and gusty south to west winds are expected starting Wednesday
afternoon; most notably along and south of the I-90 corridor within
the north-south orientated valleys of Southwest Montana, west of the
I-15 corridor over the plains of Central and North Central Montana,
and across Hill and Blaine Counties. Further enhancement of winds
are likely beneath and/or near shower and thunderstorm activity.
There is a marginal risk for severe thunderstorms across the entire
region on Wednesday but the greatest risk for dry thunderstorms
extends east of the I-15 corridor and north of Highway 200. For this
portion of North-Central Montana, the main concerns will be frequent
lightning and gusty, erratic winds that might not only start new
fires but make existing fires difficult to contain.

Probabilities for the Hot-Dry-Windy Index (HDWI) rising to within
the 95Pct of Climatology has increased to a 80% or greater chance
across most lower elevations across Southwest Montana south of the I-
90 and across Hill and Blaine Counties in North Central Montana,
with Fire Weather partners indicating that fuels would be receptive
to fire, especially across Southwest Montana. Thus, the decision was
made to upgrade these areas to a Red Flag Warning. Additional areas
across the region are still running a 20-40% chance of exceeding the
95Pct but there is not enough confidence in thunderstorm coverage to
help nudge any additional zones into a Red Flag Warning at this time.
