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. Genz $$
