What defines a heat wave?

What defines a heat wave?


Minnesota is in the midst of a sizzling stretch of summer-like weather. Something unique for this time of year. 

A packed Nokomis Beach, soaked in sunshine and steaming close to 90 degrees, would make you think it’s a mid-summer day. But it’s just mid-May.

Several beachgoers WCCO talked with described the day as hot but bearable thanks to a lake breeze. 

Still, temperatures that feel like late July for a four-day stretch had them calling it a heat wave.

What defines a heat wave?

“I think it’s in the eye of the beholder,” said Ken Blumenfeld, a senior climatologist with the Minnesota Department of Natural Resources.

According to the National Weather Service (NWS), a heat wave is a “period of abnormally hot weather generally lasting more than two days. Heat waves can occur with or without high humidity.” 

There was no specific temperature listed, but the NWS added that a heat wave often involves dangerously hot weather that could harm people.

Blumenfeld looks at heat waves from a statistical perspective. “In climatology it’s just extreme warmth relative to the time of year,” he said.

May 11 to May 14, the daily high temperature hit or was forecasted to land around 90 degrees. The average high for this time of year is around 67 to 68 degrees according to the National Oceanic and Atmospheric Administration (NOAA). That means the Twin Cities is running least 20 degrees warmer than usual.

“If it’s supposed to be like 60 right now but right now, we’re having all this heat, it’s gotta be a heat wave,” said Ambuskah Little Voice while at the beach with friends.

Blumenfeld also understands that public health workers have their own definition. 

“[They] might consider a heat wave to be something that could cause human bodies to have problems keeping itself cool naturally,” said Blumenfeld.

That’s usually in peak summer when high humidity combines with high temperatures, creating dangerous conditions leading to heat stroke and exhaustion. 

“Heat during late May and even late September and October tends to be really dry compared to the kind of heat you get in July and August,” said Blumenfeld.

If nights are comfortably cool, is it still a heat wave?

“That’s where it gets a little iffy,” Blumenfeld said.

A heat wave in mid-summer could have nights in the 70s while the air remains thick. In May, the daily low temperatures have settled in the 60s and even 50s, creating a difference of 25 to 30 degrees, even larger during this current heat wave. The air also pleasantly dry.

Could you have a heat wave in the winter?

Beachgoers said both yes and no. Heat isn’t a word typically associated with the coldest time of year, but there’s no denying that it still arrives in surprising fashion.

“We can have heat waves in winter if you’re looking at it statistically,” Blumenfeld said.

Consider late December 2023, the Twin Cities hit 55 degrees on Christmas Eve, then 54 degrees on Christmas day along with relatively high humidity. That’s extreme warmth for the holiday season, heating up the debate on how to label these steamy stretches.

“Defining a heat wave really kind of depends on who’s asking,” Blumenfeld said.

The most recent extreme heat for the month of May came in 2018. That’s when much of Minnesota hit 100 degrees on Memorial Day.

Minnesota State system updates fraud prevention measures during House hearing

Minnesota State system updates fraud prevention measures during House hearing


The Minnesota State system is fighting a growing fraud problem facing colleges and universities across the country. Ghost students are enrolling using stolen identities and receiving financial aid.

“These fraudsters are very well organized and well financed,” said Craig Munson, the chief information security officer for the Minnesota State system, during a Minnesota House hearing on Thursday. “Stealing money that was intended for real students in need of financial aid.”

According to state lawmakers, victims sometimes find out they owe on a student loan years after someone enrolled them in a college or university without their knowledge.

House members questioned Munson about how much it’s costing the system, how many students are enrolling fraudulently, and what needs to change to prevent it in the future.

“I believe we are making very good progress,” responded Munson, who did not provide a dollar amount for the cost to the system. 

He presented a report from the Minnesota State Colleges and Universities Enrollment Fraud Working Group, which was convened under a 2025 state law requiring the development of policies to prevent fraudulent enrollment.

It outlines the rising threat and includes recommendations, including enhanced training, adopting an enrollment fraud user guide, which was recently rolled out across the system, and a state investment in automated identity proofing.

“An automated identity solution is kind of that gold standard,” said Munson, in an interview following the hearing. 

He explained that an automated identity proofing system would cost $1 million to $1.5 million annually but would save on the time and labor required to check identities manually.

“The faster we can move, the better we are equipped to stop it before it blossoms into something bigger,” he said.

If the Legislature approves the funding, he expects it would take months to implement. 

“There are several on the market, and we have had extensive talks with a number of vendors already,” said Munson.

5 INVESTIGATES reported in the fall that the Minnesota State system flagged more than 7,700 applications as fraudulent or potentially fraudulent in an academic year.

“We’re seeing similar numbers right now this year in the first few months,” said Munson. “What I am pleased to say some of the changes we have made in some of our safeguards have been quite useful in stopping this.”

There has been a change since the fall, however, in which institutions are being targeted by fraudsters.

“It used to be more of the two-year [colleges], we’re starting to see they’re looking at all colleges and universities,” he said. “It could be a couple of reasons — that they’ve learned the system to its extent, and they want to extend their stay in the system and transfer to a four-year possibly. We’re also seeing some positive reports that many of our two-year colleges are seeing a little bit of a reduction in these fraud attempts.”

The Minnesota State system reports catching most of the fraud before money is paid out. A recent U.S. Department of Education report shows nearly $90 million has gone to ineligible recipients nationwide.

Ex-Minnesota corrections officer accused of falsely claiming to be U.S. citizen

Ex-Minnesota corrections officer accused of falsely claiming to be U.S. citizen



A former Minnesota corrections officer is facing deportation and criminal charges that accuse him of more than a decade of citizenship deception.

According to the Department of Homeland Security, 45-year-old Morris Brown was arrested by U.S. Immigration and Customs Enforcement officers in Minneapolis on Jan. 15. 

DHS said the Liberian national last entered the U.S. in 2014 with a nonimmigrant student visa, which was terminated the following year because Brown failed to enroll in a full course of study.

U.S. Citizenship and Immigration Services Director Joseph Edlow claimed Brown “tried every trick in the book” to stay in the country after losing his legal status. 

“We will use every tool at our disposal to ensure he faces justice for his many violations of the law,” Edlow said. 

Federal officials said they found out during Operation Twin Shield last September that Brown was working as a Minnesota corrections officer. The operation targeted immigration fraud in the Minneapolis and St. Paul metro area.

DHS said Brown now faces removal proceedings and possible criminal prosecution for immigration fraud, false claims to U.S. citizenship and other related offenses. 

In a statement, the Minnesota Department of Corrections said it has cooperated with the investigation and followed federal document verification requirements while hiring Brown. He worked for them from May 2023 until last October.

“If these federal allegations are accurate, this individual engaged in sophisticated efforts to misrepresent their identity, extending well beyond Minnesota,” DOC Commissioner Paul Schnell said. “We are grateful to USCIS and ICE for their work in investigating and addressing immigration fraud.”

Brown is also accused of joining the Pennsylvania Army National Guard in 2014 and going AWOL the next year. DHS officials said he was taken into custody and discharged from the military “under other than honorable conditions in 2022.” Two years after the discharge, Brown applied to naturalize as a U.S. citizen based on prior military service in what DHS alleged was “another commission of fraud.”

According to ICE records, Brown is now at an immigration facility in El Paso. It wasn’t immediately clear if he has an attorney.
