...Conditions Worsening in Northeast Iowa...

.The combination of new snow and strong northwest winds are
leading to more drifting, poor visibilities, and related traffic
accidents across mainly northeast Iowa at mid afternoon. Because
of this an extra area of warnings is being extended.

Meanwhile snow will continue to pile up mainly on the Wisconsin
side with 3 to 7 inches possible. Winds gusts of 25 to 40 mph 
will cause blowing and drifting snow through this evening. This 
may result in pockets of whiteout conditions, mainly in open areas
of northeast Iowa and southeast Minnesota.

Travel will remain poor to hazardous in most areas this afternoon
and tonight.
