Forecast Ice Impacts
Hazardous Travel, At Least
A swath of the central Plains, Upper Mississippi Valley and Great Lakes should see at least hazardous roads, particularly untreated roads, bridges and overpasses, for a time through Tuesday.Monday, some southernmost areas that experienced ice this past weekend will see rain, or at least above-freezing temperatures, helping to thaw out any frozen roads.
The exception will be in parts of the Texas panhandle, western Kansas and western/central Nebraska where temperatures may struggle to rise much above freezing, keeping the threat of hazardous roads in play, and where snow may fall on the previous ice accumulations.
Some pockets of the interior Northeast Tuesday into Tuesday night may see a light glaze of ice, as well.
Damage/Power Outage Potential
Additional ice accumulations capable of tree/power line damage, and power outages, will be confined to a relatively small strip of the Upper Midwest going forward.More than a quarter-inch of ice may accumulate in these areas.
