...Utah through the Northern Rockies...
Days 1-3...

The closed 700-500mb low currently over central Nevada is
advecting moderate moisture northward via a southerly flow over
the Wasatch and Uintas through this evening with snow levels
generally around 9000ft.  The best prospects for the heaviest snow
remain across the higher terrain of the Uintas with 6-12 inches of
total snow expected.  A secondary reinforcing shortwave trough
pivots around the main upper low and keeps snow showers continuing
through Monday as well from Utah northward into western Wyoming
and eastern Idaho, generally above 8000-9000 feet.  Continued
troughing over the northern Rockies will result in light to
locally moderate showers with snow levels around 8000ft Tuesday
for most areas.

The probability of any ice accumulation across the Continental
U.S. is less than 10 percent.
