Precipitation is forecast to continue dissipating over the higher
elevations of the Rockies today and into tonight. Additional
snowfall totals of up to 6 inches, with locally higher amounts
possible, are expected in various portions of the Intermountain
West. 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 today 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 8 to 12 inches of additional 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 accretions exceeding
0.25 inches are likely from portions of eastern Nebraska through
southern Minnesota and Wisconsin, 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 900 PM CST. Please refer to your local National Weather
Service office for additional information on this event.
