Area Forecast Discussion
National Weather Service Missoula MT
341 PM MST Mon Feb 26 2024

.UPDATE...Added winter weather advisory for Lower Clark Fork
region through 1100 AM MST Tuesday morning.

&&

.DISCUSSION...Regional radar imagery shows a plethora of
convective snow showers transversing across eastern Washington
into the ID/MT border. Short periods of heavy snow have been
observed under these convective showers as seen on Lookout Pass
webcams during the last hour. Therefore, a winter weather advisory
has been issued for the Lower Clark Fork region as snow showers
will continue to bring periodic impacts to travel, particularly
across Lookout Pass. /Lukinbeal

&&

.AVIATION...Widespread snow showers are developing along the ID/MT
border this afternoon and will spread across western Montana
through the evening and overnight hours. These showers are
expected to periodically reduce visibility down to 1SM at KGPI,
KMSO, KBTM and KSMN, through Tuesday morning. While overall
probabilities are low for more than an inch of snow, any one of
these showers will be capable of producing half inch snow rates
after sunset this evening. Westerly wind gusts up to 30kts are
also expected as the convective showers move overhead. Scattered
mountain snow showers will persist throughout the day Tuesday.

&&

.PREV DISCUSSION... /ISSUED 231 PM MST Mon Feb 26 2024/

DISCUSSION...The cold front has pushed through the Northern
Rockie today leaving behind breezy conditions and widespread snow
showers. An arctic airmass has been making its way over the
Continental Divide around Glacier NP today causing an
intensification of snow along with rapid drop in temperatures.
This arctic air will continue to infiltrate valleys along the
Continental Divide tonight causing the potential freeze up of wet
surfaces. Also a few subtle disturbance will keep showers
lingering throughout the night, which could cause light snow
accumulation in the valleys by Tuesday morning commute.

The upper level flow pattern becomes southwesterly by Wednesday
which pushes in another significant plume of subtropical moisture.
Snow levels will be steadily rising to 4000-5000 by Wednesday
afternoon, keeping snow limited to the higher terrain. Steady snow
is expected to impact portions of north central Idaho and
northwest Montana starting late Tuesday night through Thursday
morning. Then a cold front will push the moisture southward on
Thursday. By Friday morning the mountains, especially along the
Montana/Idaho border, will once again receive around 12-24 inches
of snow. While the valleys will mainly experience rain
transitioning over to snow on Thursday. Any snow accumulations in
the valleys will be primarily well after the frontal passage.

The aforementioned cold front on Thursday will also bring breezy
to windy southwesterly winds to the Northern Rockies. A good
portion of north central Idaho and west central Montana, south of
Highway 200 corridor, should experience wind gusts in excess of 40
mph. The latest model guidance is indicating that the Camas
Prairie in Idaho, around Grangeville, has around a 70% chance of
wind gusts to 60 mph Thursday morning.

A broad trough of low pressure will be over the Northern Rockies
Friday into the weekend keeping temperatures below seasonal
averages. A few weak disturbances are expected to move through the
region during this period which will bring widespread snow with
the potential of actual accumulations in the valleys.

AVIATION...Widespread snow showers are developing along the ID/MT
border this afternoon and will spread across western Montana
through the evening and overnight hours. These showers are
expected to periodically reduce visibility down to 1SM at KGPI,
KMSO, KBTM and KSMN, through Tuesday morning. While overall
probabilities are low for more than an inch of snow, any one of
these showers will be capable of producing half inch snow rates
after sunset this evening. Westerly wind gusts up to 30kts are
also expected as the convective showers move overhead. Scattered
mountain snow showers will persist throughout the day Tuesday.
