18Z DISCUSSION:

A shortwave trough slides through the region today, bringing winter
weather impacts to much of the region. This will result in MVFR/IFR
conditions at many terminals along with persistent mountain 
obscurations through the period. 

At KJAC, snow showers will persist through much of the day, tapering
off overnight. Light snow showers will continue to be possible 
through Tuesday morning, as lingering energy from the exiting trough
will bring a few more waves of precipitation. Most of the additional
impacts after 07Z tonight will be over the mountains, with the 
valley being primarily shadowed, however, there was enough 
confidence to include a PROB30 for the overnight/morning snow 
showers.  

Most other terminals will have a brief period of snow. For west of 
the Divide terminals (KBPI, KPNA, and KRKS) this will come near the 
beginning of the period. For east of the Divide terminals (KCOD,
KCPR, and KWRL) snow impacts will be later afternoon into the 
evening. 

There is a slight chance for fog tomorrow morning, most notably
for KBPI and KPNA. Have indicated this chance with a FEW002 group.
Winds will also be gusty through much of the period, with a lull 
for most terminals overnight. Winds will increase again by 14 to 
16Z Tuesday. 

Please see the Aviation Weather Center and/or CWSU ZDV and ZLC for 
the latest information on icing and turbulence forecasts.
