Iowa
Iowa will be the coldest state in the US. Maps show how cold it’ll be.
What is the polar vortex? How it can impact snow, freezes in the U.S.
The polar vortex is a large area of circulating cold air above the North Pole. Strong winds keep it contained, but when it weakens, it can wobble and stretch.
Temperatures across Iowa are forecast to plunge to the coldest in the Lower 48, dipping well below zero as a surge of Arctic air sweeps in.
The broader weather pattern will stay active and winter-like through the end of the week and into the weekend. A recent stratospheric disturbance weakened the polar vortex, allowing frigid Arctic air to spill into the U.S. and shift the jet stream, bringing snow and wintry precipitation to several regions.
While the heaviest snow will target the Rockies and High Plains on Dec. 3, Iowa will primarily feel the effects of a strong cold front and fast-moving clipper systems sweeping through the Great Lakes and Midwest.
“An active winter-like pattern will continue to bring the threat of winter weather to multiple areas of the country through the end of the week and into the weekend,” the Climate Prediction Center said.
When is the coldest air expected in Iowa?
Dangerous cold will dominate the forecast through Thursday, Dec. 4. Record-breaking lows are likely early Thursday, and even daytime highs will struggle to climb out of the single digits and teens. Winds will ease overnight, but the extreme cold will persist.
By Friday, Dec. 5, temperatures moderate slightly, but the pattern remains active into the weekend.
When will temperatures warm up in Iowa?
After the deep freeze, a gradual warm-up arrives Friday, Dec. 5, though temperatures will still run below normal.
The weekend and early next week look unsettled, with a series of disturbances tracking through the Midwest. While confidence in timing and amounts remains low, light snow chances will return periodically. Anyone with travel plans should monitor updates closely, as even light snow combined with cold conditions could impact roads.
Is snow expected in Iowa?
Light snow showers are possible today, Dec. 3, along the trailing cold front.
Additional chances for snow are possible on Thursday, Dec. 4, as another clipper system passes through. Accumulations in Iowa should remain light, but the bitter cold will dominate the story, with temperatures running well below normal for early December.
Several weak systems will ripple through the region, bringing occasional chances for light snow. While significant accumulations appear unlikely, even minor snowfall could cause hazards as low temperatures keep roads slick.
“Anyone with travel plans this weekend should monitor the latest forecast updates, because while at this time the probability of a significant snowfall event is low, even lighter accumulations could still impact travel conditions at times,” the National Weather Service office in Des Moines wrote.

IOWA CITY, Iowa (KCRG) — Volunteers broke ground Saturday for Iowa Valley Habitat for Humanity’s 16th Woman Build, honoring a retired University of Iowa nursing professor.
Liz Swanson, a retired nursing professor, was chosen as this year’s honoree for her decades of impact. The Women Build program focuses on including women in every step of home construction.
While the home is built in Swanson’s honor, it will go to a fellow nurse and mother of three. The family applied through the affordable housing program.
Swanson said she’s proud to be part of a project that directly connects to her nursing legacy.
“It’s very special to have the unique opportunity to help the nurse who is working nights,” Swanson said.
Swanson said stable housing gives families the security to plan for the future.
“It means security for families. We talked briefly to the children and they said, ‘we’re gonna have our own bedroom,’” Swanson said.
Volunteers are set to begin work on the home in August. Those interested in volunteering can find more information here.
