Iowa — A sharp November chill is settling across central Iowa, with temperatures expected to plunge into the low 20s before the weekend. Des Moines could experience a 24 degree temperature swing as brisk winds give way to clear skies and freezing nighttime conditions.
According to the National Weather Service in Des Moines, Thursday brings partly sunny skies and a high near 46 degrees. A chance of sprinkles continues between 7 a.m. and 1 p.m., while north winds could gust to 20 mph.
The more significant change arrives as temperatures fall toward 27 degrees Thursday night, followed by an even colder Friday night.
Temperatures Plunge to 22 Degrees Friday Night Friday, November 13, brings partly sunny skies that gradually turn sunnier, with a high near 43 degrees.
However, clear skies Friday night will allow temperatures to drop toward 22 degrees.
That represents a 21 degree difference between Friday's daytime high and nighttime low.
Compared with Thursday's 46 degree high, temperatures will have fallen 24 degrees by early Saturday.
For residents across Polk County and the greater Des Moines metropolitan area, the coldest period could affect early weekend activities.
Drivers using Interstate 35, Interstate 80 and Interstate 235 should watch for isolated slick spots where moisture remains on untreated surfaces.
Although widespread icy travel is not indicated, temperatures well below freezing can create hazards where water is present.
Saturday Brings Sunshine, but Cold Air Remains Saturday, November 14, looks bright but chilly.
The National Weather Service expects sunny skies and a high near 45 degrees, with calm winds.
Saturday night brings another round of freezing temperatures, with lows near 26 degrees.
Residents planning outdoor activities should keep winter jackets nearby, particularly during the morning and evening.
The dry weather also offers an opportunity to finish leaf cleanup, secure outdoor decorations and prepare vehicles for colder conditions.
Sunday Begins a Gradual Warmup Sunday, November 15, brings another sunny day, with temperatures reaching approximately 47 degrees.
Mostly clear skies continue Sunday night, when temperatures fall near 29 degrees.
Monday offers additional improvement, with sunshine and a high around 51 degrees.
By Tuesday, temperatures could climb to 55 degrees, followed by 57 degrees Wednesday.
That represents a substantial recovery from Friday night's expected 22 degree low.
What About Snow Before Thanksgiving? The NOAA Weather Prediction Center reports that polar air is spreading across the eastern United States, bringing freezing temperatures to a broad area.
However, the current Des Moines forecast does not indicate snow or accumulating winter precipitation through Wednesday.
For now, freezing nighttime temperatures remain the primary concern.
Residents should continue monitoring updated weather information as Thanksgiving approaches, especially as November weather patterns evolve.
