.DISCUSSION...A low pressure trough was gradually migrating east
of the area early this morning while light snowfall lingered over
the mountains. A drier northwest flow is expected to spread into
the area late this afternoon and evening ahead of the next
approaching disturbance. This second system digs into the
northwest states late tonight while attending scattered snow
showers work into the Wood River region Wednesday.
