IOWA — We are replacing the deep chill we’ve had the last few days with slightly warmer temperatures and freezing rain.

A Winter Weather Advisory will be in effect from 4 PM Friday to Noon on Saturday for all of Central Iowa. A small area of Eastern Iowa counties, including the communities of Newton, Grinnell and Marshalltown, are part of an Ice Storm Warning beginning at 8 PM tonight through noon on Saturday.

This is where ice accrual will be highest and a two-tenths of an inch to three-tenths of an inch of ice may accrue on roads, trees and powerlines.

An area of low pressure is lifting north from the panhandle of Oklahoma and will bring increasing moisture and temperatures. Warm air will be overriding cold air here at the surface in Iowa. The rain will fall high above in the atmosphere and hit the cold freezing temperatures here at the surface, leading to the freezing rain on roads, trees and powerlines.

The freezing rain looks to begin in the Des Moines Metro after 6 PM and continue through 10 AM Saturday.

Temperatures will rise through the night but stay below freezing here at the surface. Warmer temperatures aloft will allow the precipitation to fall as rain, but hit the below freezing temperatures here at the surface and freeze on contact.

We will warm to the mid-to-upper 30s during the day on Saturday, so continued scattered showers are expected through the day. Sunday will be cloudy but warmer with highs in the low 40s.
