CEDAR RAPIDS — Corridor residents should expect the first frost of the season, as Linn and Johnson counties are among those in a freeze warning overnight.
According to the National Weather Service, a freeze warning is in effect from 2 to 9 a.m. Thursday across several Iowa counties.
The warning states light winds and clear skies “will allow temperatures to plummet below freezing in many locations,” causing widespread frost.
Temperatures are expected to drop to 32 degrees overnight, according to the National Weather Service, but Zach Uttech, a meteorologist with the National Weather Service in the Quad Cities, said temperatures could go even lower — into the upper 20s.
“If you want to protect those plants, you have to cover them,” Uttech said.
The National Weather Service warns that such temperatures can kill vegetation, including field crops and flowers and plants in gardens.
Thursday’s forecast calls for a high temperature of 57 degrees before the mercury dips back to 38 degrees Thursday night.
After that, warmer weather is expected to return.
Friday calls for a high of 65 degrees and a low of 54 degrees.
There’s a chance for showers and thunderstorms on Saturday, but temperatures are expected to reach 73 degrees during the day and 57 degrees at night.

Sunday’s forecast calls for mostly sunny skies with a high of 73 degrees and a low of 58 degrees.
“It’s the time of year, we’re getting bigger (temperature) swings,” Uttech said, noting the fluctuation is not uncommon.
Warmer temperatures are expected to continue Monday with a high of 76 degrees and low of 58 degrees, according to the National Weather Service.
Uttech indicated it’s probably a good idea to enjoy the warm weather while you can. Though an official winter outlook won’t be issued by the National Weather Service for a few more weeks, Uttech said residents should expect to have colder temperatures this year, particularly in comparison to the mild winter last year.
