   Areas affected...portions of northern Idaho into extreme western
   Montana

   Concerning...Heavy snow 

   Valid 111725Z - 112030Z

   SUMMARY...Heavy snow should continue for at least a few more hours,
   with 1-2 inch/hr snowfall rates common. Reduced visibility is likely
   in the heavier snow bands.

   DISCUSSION...A low-level cyclone is drifting southeast across the
   Idaho Panhandle into extreme western Montana as a mid-level impulse
   traverses the International border, providing deep-layer ascent.
   Latest mesoanalysis and RAP forecast soundings characterize vertical
   profiles as near saturated, with deep-layer steep lapse rates,
   supporting a sufficiently deep and moist dendritic growth zone to
   support continued 1-2 inch/hr snowfall rates given strong lift in
   place. Latest high-resolution guidance suggests that at least brief
   bouts of heavy snow and perhaps reduced visibility should continue
   through at least 21Z.
