Precipitation is forecast to continue in the higher elevations of
the Rockies through tonight then taper off on Tuesday. Additional
snowfall totals of 2 to 10 inches expected with locally higher
amounts possible. The system is forecast to intensify while
tracking northeast across the Central Plains to the Upper Midwest
through midweek. A large swath of moderate to very heavy snow,
significant freezing rain, and sleet is expected across the Plains
through Tuesday and across the Upper Midwest through Wednesday.
Intense snowfall rates of 1 to 3 inches per hour are likely from
parts of Nebraska and South Dakota into Minnesota with more than
12 inches of snow forecast for this region. Gusty winds
accompanying the system will result in blowing snow, causing snow
covered roads, reduced visibility, and dangerous travel. Localized
significant ice accumulations exceeding 0.25 inches are likely
from portions of eastern Nebraska through southern Minnesota,
which could damage trees and power lines. The storm system will
linger over the Upper Midwest while weakening late in the work
week, then push towards the Northeast this weekend.
The next Storm Summary will be issued by the Weather Prediction
Center at 800 AM MST. Please refer to your local National Weather
Service office for additional information on this event.
