DISCUSSION: 
A weak winter storm cycle will exist over the region for at least
the next week beginning Friday afternoon.
Snow levels will be just above valley elevations for much of the 
first system, with up to 8 inches total accumulation at pass 
elevations today through Saturday. Wind gusts over 40 mph along 
the Continental Divide will make backcountry travel difficult 
through tonight. Winds lighten up by Saturday midday.
The following storm system on Sunday- Monday will have similar 
snow and wind concerns along Continental Divide as well. A much 
colder pattern will arrive for the latter half of next week, 
however no significant breaks between mountain snows anticipated.
