Des Moines, IA – The National Weather Service in Des Moines has issued a Frost Advisory for much of central, western, and north-central Iowa as temperatures are expected to fall to around 32°F overnight, leading to widespread frost formation early Wednesday morning, October 22.
The advisory is in effect from 2 a.m. to 9 a.m. CDT Wednesday and includes major counties such as Polk, Story, Boone, Dallas, Madison, Warren, and Carroll. Communities including Des Moines, Ames, Marshalltown, and Fort Dodge are all within the advisory area.
