A surface low pressure system over the northern Plains this
morning will pull away from the region, while the deep upper-level
low over the Northwest very slowly moves off to the east over the
next couple of days. Some snow showers associated with the
upper-level low may generate locally a couple more inches of
accumulation across the higher terrain of the northern Rockies and
northern Sierra Nevada today through Tuesday, but otherwise the
snow will taper off and come to an end.

This will be the last Storm Summary issued by the Weather
Prediction Center for this event. Please refer to your local
National Weather service office for additional information.
