.DISCUSSION...

Update:
Going forecast in pretty good shape. Still cloudy south of a Malta
to Glasgow-Wolf Point to Sidney line. Not looking for much change
in sky conditions but radar echoes over central and south-central
Montana should move SE and away from CWA today, therefore kept
weather grids silent. Temps won`t be too tough as sunshine should
allow temps to reach the 30s north (30s south with clouds). TFJ

Previous Discussion...
Cold front moved through the region last evening with a few rain
or snow showers. Skies beginning to partially clear across the
north, although higher clouds spreading across the mountains as
the upper trof digs into the Great Basin.

Upper flow flattens out for early next week as the northern
portion of the upper trof moves east. This will result in cooler
temperatures for northeast Montana, although still a bit above
normal. Another shortwave pushes a cold front out of Canada on
Monday with the potential for mixed rain and snow showers. Amounts
are expected to be very light. Shortwave digs the trof to the east
enough to begin to pull some arctic air into the northern plains.
This sets the stage for some overrunning precipitation to develop
on Tuesday night as a shortwave trof dives through the Pacific
northwest and into the Great Basin. Still enough model differences
for low confidence for snow chances, but if it pans out could be
enough for a white Christmas over northeast Montana. Surge of cold
air behind the system could finally drop temperatures to near
normal for late December. Ebert
