For today: Light freezing rain will continue on-and-off across far southeast Nebraska and southwest Iowa this (Sunday) morning. The Main brunt of the storm system will enter the area tonight into Monday and Monday night, bringing a mix of rain…freezing rain…sleet and snow.

Elsewhere in the Winter Storm Watch area, freezing rain will develop later tonight before quickly changing to all snow Monday morning. Additional snowfall and other mixed wintry precipitation of varied intensities will occur later in the day, Monday, before switching to main all lighter snow Monday night or Tuesday.

The National Weather Service predicts anywhere from three-to five-inches of snow will fall in Cass and surrounding Counties, with eight-inches or more further into northwest Iowa. Ice accumulations amounting to several hundredths of an inch may precede the snow.
