.DISCUSSION...
Upper low over the region continues to weaken and drier air moving
into the northern Montana. This will bring the light snow/flurries
to an end over northeast Montana this evening, and with clearing
skies temperatures should drop into the teens below zero. A little
stronger north wind is expected to develop overnight, and this
will help push wind chills toward minus 30 for most of the region.
Have issued Wind Chill Advisory for all zones for overnight and
into Tuesday morning.

Upper trof over the region expected to dig southward over the next
few days before lifting into the central Plains. To the west,
another shortwave will dive down the western Canadian coast, and
dig an upper low into the Great Basin by Thursday. This should
send moisture back northward to overrun another Canadian high
pressure, and produce some snow over Montana Wednesday night into
Thursday morning.

As the Great Basin low moves south and east through the end of the
week, expect dry weather for northeast Montana. Next system to
impact the region could move into the northern Rockies on Sunday.
