...WINTER STORM WARNING IN EFFECT FROM 5 PM THIS AFTERNOON TO
8 PM MST THURSDAY...

The Winter Storm Watch is no longer in effect. 

* Impacts/Timing: The primary concern will be snow loading issues
  for roofs and other structures, as heavy, wet snow is followed
  by rainfall. Another round of heavy snowfall is expected
  beginning late this afternoon and continuing into Thursday.
  Valley locations will start as snow but transition to a wintry
  mix of freezing rain and snow early Thursday morning, then
  become rain by mid morning Thursday. Snow and freezing rain will
  create difficult travel. Once again, the weight of wet snow along
  with rain on top of snow may worsen or lead to additional snow 
  loading issues for roofs and other structures.

* Snow accumulations: Valley locations 4 to 8 inches of heavy, 
  wet snow. Over a foot of snow is likely for higher elevations. 

* Locations impacted include: Highway 2 Kalispell to Libby, 
  Highway 37 Eureka to Libby, Highway 56 Bull Lake Road, and
