There is a risk for ice movement and ice jams on local rivers due snowmelt and rainfall today. Concern is highest for the Platte River from Columbus to Ashland, and also in the Loup and Elkhorn Rivers in eastern Nebraska. If any ice jams develop, they may combine with increased runoff from today`s rain to produce localized flooding.
Rain will change to snow over northeast Nebraska this evening, combining with 50 mph wind gusts to result in hazardous travel conditions with poor visibility and slick roads. Colder temperatures over the wet roads will also produce a flash freeze, leading to increasingly slick conditions overnight.
The best chance for a few inches of snow is in Knox and Cedar counties where a winter weather advisory has been issued.
There is a small chance for a severe storm to produce isolated hail, damaging wind, or a tornado south of a Pawnee City to Hamburg to Clarinda line this afternoon.
A long narrow band of several inches of snow is expected across portions of southeast Nebraska and southwest Iowa Wednesday evening through Thursday morning. Northerly winds gusting near 40 mph may result in blowing and drifting snow. Travel impacts are likely Wednesday night and Thursday morning.
