.DISCUSSION...

Increased pops slightly over the central and western zones this
morning. Snow showers have produced an inch of snow in the Larb
Hills south of Hinsdale, but activity should be mostly gone by the
mid-afternoon. TFJ

Previous Discussion...
A shortwave trough will move through Central and Eastern Montana
today. This wave will have enough moisture and energy for
scattered snow showers mainly over the western half of the
forecast area this morning. Cloudy skies are expected for most of
today with a very cold air mass which will keep temperatures much
colder than normal for highs today. 

Shortwave ridge tonight and Friday will bring a brief warm up 
before a cold front move through Friday evening with an upper
trough Friday Night and Saturday. Limited moisture is expected with
the system but there will be gusty northwest winds with cold
temperatures that will only be in the 30s for highs on Saturday. 

High pressure Saturday Night will diminish the winds but the cold
air remains in place on Sunday with highs only near 40.  

The NW flow will send another shortwave through the area on Monday
and bring warmer temperatures with a chance of rain in the north. 

Upper ridge on Pacific Coast moves inland during the week which
will bring several days of dry and warmer weather. Forrester

most of the time today with scattered to broken mid and low
clouds. Skies will clear this evening and remain clear overnight
with VFR conditions except where patchy fog lowers visibility.
Winds will be light and variable today and tonight.
