lesser amounts down into the central mountains. A Winter Weather

inches of snow forecast there. Blowing snow and slick roads on the

mountain snow showers. This could impact holiday travel, as well as
morning commutes Sunday into Monday with winter driving conditions
on the mountain passes. Additional mountain snow looks possible for
Tuesday afternoon and beyond, with some uncertainty in the forecast
at this point.

.SPOTTER INFORMATION STATEMENT...
