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.

Watch as Gov. Kim Reynolds reveals Iowa Office of Outdoor Recreation
Gov. Kim Reynolds signs an executive order June 8 creating an Iowa Office of Outdoor Recreation within the Iowa Economic Development Authority.
Iowa’s director of Health and Human Services has resigned after the Iowa Senate blocked his confirmation in April, but he will stay in leadership as deputy director.
Larry Johnson was appointed to succeed Iowa Department of Health and Human Services Director Kelly Garcia in September 2025. Johnson took over the department in October.
Johnson’s confirmation in April, however, was blocked by Iowa Senate Democrats. Johnson received the support of 28 senators, six votes short of the 34 needed.
“Hundreds of thousands of Iowans rely on the Department of Health & Human Services, but under Mr. Johnson’s leadership, those Iowans have been met with diminished care and services and a disrespectful lack of transparency and communication,” Iowa Senate Democratic Leader Janice Weiner said in a statement at the time of Johnson’s confirmation block. “Senate Democrats believe Iowans deserve more responsible leadership for such an important executive department.”
Under state law, 60 days after the Iowa Senate disapproves a person’s appointment, the nominee must step down. Johnson’s resignation came June 19, 58 days after his confirmation was blocked.
In a news release Friday, Gov. Kim Reynolds appointed Kraig Paulsen, the director of the Iowa Department of Management, to also serve as the director of Iowa Health and Human Services.
“This is not the first time I’ve called upon Director Paulsen to help lead executive branch departments during times of transition,” Reynolds said in a statement. “His experience across state government is unmatched, and I have full confidence in his ability to ensure our state’s largest agency has the leadership team required, not only to serve Iowans most in need of assistance, but also to advance strategic initiatives such as rural health transformation, cancer research, and child welfare technology improvements.”
Paulsen named Johnson as principal deputy director of the department to “ensure efficient and effective operations,” according to the release.
“Iowa HHS requires strong and experienced leadership at every level to ensure continuity of critical services such as Medicaid, SNAP, and child protection, and Larry Johnson is exactly that leader,” Paulsen said in the release. “I look forward to working closely with Principal Deputy Director Johnson to ensure Iowa’s strong commitment to our most vulnerable citizens continues as usual.”
Weiner, in a statement issued June 19, said Reynolds “has decided to blatantly disregard and circumvent the Senate in re-establishing Larry Johnson as the de facto head” of Health and Human Services.“This is partisan politics of the worst kind,” Weiner said in the statement. “Under Larry Johnson, the hundreds of thousands of Iowans who rely on HHS for critical services have received a diminished standard of care, a disrespectful lack of responsiveness, and a department more concerned with fealty to the governor than transparency to the public. And yet, this governor simply cannot handle a world in which she doesn’t get her way, so she has invented a title that allows Johnson to resume his work.”
Weiner said the decision to not confirm John was “not made lightly,” and “We did what was right for Iowans.”
“Our goal has been and remains to work within the bounds of the Senate for the benefit of all Iowans,” Weiner said. “Unfortunately, Gov. Reynolds would rather play politics than give Iowans the respect of a more diligent search for a qualified candidate.”

DES Moines, Iowa — Gov. Kim Reynolds has ordered all flags in Iowa to be lowered to half-staff Saturday in honor of state Sen. Julian Garrett, who died June 8 at the age of 85.
Flags will be flown at half-staff from sunrise to sunset June 20, the day of Garrett’s funeral, on the Iowa Capitol Building and across the Capitol Complex. The order also applies to all public buildings, grounds and facilities throughout the state.
Garrett served 16 years in the Iowa Legislature, first representing House District 55 from 2011 to 2013 before serving in the Iowa Senate through the 2026 legislative session.
In addition to his legislative service, Garrett was a farmer, attorney and former employee of the Iowa Attorney General’s Office.
“Sen. Garrett was a friend who served our state with integrity — whether as a cattle producer, a Little League coach, an attorney in the executive branch, or a legislator,” Reynolds said in a statement. “For 15 years, we worked together to unleash opportunities for the Iowans we served, and his impact will be felt for generations to come.”
Reynolds is encouraging individuals, businesses, schools, municipalities, counties and other government entities to lower their flags to half-staff during the same time period as a sign of respect.
Garrett represented southwest Iowa in the Legislature and was known for his work on judiciary and agriculture-related issues during his tenure at the Statehouse.
