At 600 AM PST...A deep upper-level low interacting with a couple
of frontal boundaries continues to bring scattered snowfall across
the northwestern U.S. A surface low pressure system with an
estimated central pressure of 1007 mb...29.74 inches of

California. Meanwhile, another surface low with an estimated
central pressure of 998 mb, was located over central Idaho with a
cold front extending southwestward across Nevada into central
California. Satellite imagery, National Weather Service radar and
surface observations indicated that scattered areas of snow were

higher elevations of northern California and down along the Sierra
Nevada. Rain was the precipitation type for the immediate coast

The surface low pressure system off the coast of northern
California is expected to move onshore and dissipate today.
Scattered snow currently over the interior Pacific Northwest is
expected to gradually taper off today as the upper-level system
moves farther to the south and east. However, another low
pressure center forming along an arctic front off Vancouver Island
is expected to bring the next round of snow into the Pacific
Northwest by tonight. Meanwhile, snow across the higher
elevations of California including the Sierra Nevada and across
the Great Basin is expected to taper off tonight as the cold front
moves farther to the east. Looking farther ahead, the entire
system currently impacting the West is expected to be re-energized
as it moves into the central Plains on Monday. A low pressure
system is forecast to intensify and spread snow and wintry
precipitation rapidly across the upper Midwest, Great Lakes, and
towards the Northeast on Tuesday. On the southern edge of the
storm, heavy rain will be likely across portions of the
mid-Mississippi Valley through early Tuesday.
The next storm summary will be issued by the Weather Prediction
Center at 100 PM PST. Please refer to your local National Weather
Service office for additional information on this event.
