Area Forecast Discussion

.SHORT TERM...for northeast Montana...today through Wed...

Forecast challenges in the short term forecast period will focus
on the chances for light snow today through tomorrow and the
uncertainty of surface temperature variations given this
persistent low level cloud deck over the area.

Regional mosaic radar imagery is now showing steady snow showers
over over western Montana now moving out over central Montana
overnight and into this morning. The virga beginnings of these
snow showers for our area are now beginning to sneak into our far
western zones this morning. Those chances for snow will continue
to gradually increase through our western CWA today. Recent model
consensus continues to transition this snowfall more through our
southern zones later tonight and through Tuesday. Expect overall
impacts to be minimal as precip amounts will be light if any at
all. Our SW Phillips county might see an inch of new snow from
this event over the course of a few days. Other locations are
expected to see less than one inch.

The general overall upper-level large-scale low pressure trough
will persist over the region keeping skies at least mostly cloudy
through most of this week.

.LONG TERM...Wed night through Mon...

Canadian high pressure moves across the region on Thursday with
midweek snow shower ending and cooler temperatures. Upper ridge
then pushes over the Rockies for drier weather through the end of
the week.

As a Pacific shortwave pushes into the top of the ridge over the
weekend, with warm Alberta chinook will spread south into
Montana. By early next week, cooler temperatures and the chance
for snow will return with a cold front as the Pacific shortwave
slides into the prairies.
