Area Forecast Discussion
National Weather Service Missoula MT
425 AM MST Tue Nov 26 2019

...Strong Winds across the Northern Rockies Tonight through
Wednesday...

.DISCUSSION...A weak disturbance continues to make its way across
north central Idaho into west central Montana. Currently, light
snow is impacting the Camas Prairies up into Elk City and then
transition into the southern Bitterroot valley. Winter weather
advisories are in effect for this subtle feature.

A strong low pressure system is still on track to move into the
western United States by tonight and linger through the end of the
week. The biggest impact from this low pressure system will be the
strong northeasterly winds across the Northern Rockies starting
tonight and lasting through at least Wednesday. The strongest
winds appear to be across northwest Montana, as sustain winds of
25 to 45 mph will be possible by Wednesday morning. Gusts up to 60
mph could occur across portion of Lincoln and Flathead counties,
particularly at the mouth of Bad Rock canyon and along the Mission
mountains. The winds will begin to subside Wednesday night into
Thursday.

Moisture will be fairly limited with this low pressure system.
Areas east of the Continental Divide has the best chance of
receiving accumulating snow. The combination of the snow and wind
will create dangerous conditions tonight through at least
Wednesday. A secondary feature appears to make its way across
Lemhi county into southwest Montana on Thanksgiving which will
bring light snow accumulations, but the winds will already be on
the down trend by then. Gilmore summit and Homestake pass could
receive a couple of inches.

The next concern from this system will be the cold air that gets
pulled into the Northern Rockies. Temperatures will dramatically
drop by the end of the week. The combination of wind and colder
readings will create impactful wind chills by Wednesday morning as
readings around zero will be common across western Montana and in
the teens across north central Idaho. Even after the winds
diminish, the cold air will settle into the region and continue to
drop each night. Minimum temperature readings Friday, Saturday and
Sunday morning will be well below normal for this time of year, as
most locations will be the single digits to mid teens.

This large low pressure system will begin to move off to the east
during the weekend. The path of the exiting system will keep the
impact from snow out into eastern Montana and the Dakotas. As the
Northern Rockies will just remain entrenched in cold air.

The latest model runs are indicating that the region will be under
more of an active weather pattern by the start of next week as
weak disturbances make their way through the region. These feature
will bring scattered showers to the region and help erode the cold
air.

.AVIATION...Expect cloudy skies today with a few light snow
showers possible at all terminals between 26/1900z and 27/0100z.

aviation concerns are expected to enter the region beginning
