An early glimpse of spring may bring hazards for some Iowans. Just days after bitter windchills and record lows, a warm front promises to melt away all the snow and ice in Iowa. There’s still frost in the ground, and that’ll mean all the snowmelt will run off fast. Though rivers are low right now, that will mean a big change, and forecasters warn there’s a good chance for rain or even thundershowers early next week. All the water combined with ice breaking up on the rivers could mean spot flooding caused by ice movement or rapid rain runoff.
