.an atmospheric river will bring a lot of moisture to the northern
rockies saturday night and sunday. a lot of uncertainty remains in
the snow levels, hence the watch instead of advisories or
warnings. due to the high precipitation rates expected with this
event, an error of a few hours in the timing of the rising snow
levels will lead to a big difference in the actual snowfall. the
watches will be transitioned to warnings or advisories as
warranted when confidence in the snow level forecast increases.
