A fire department spokesman said there were destroyed roofs and fallen trees throughout the city.
Windows shattered and cars were destroyed by falling branches.
The municipality of Altenbeken near Paderborn reported that some of the trees had already snapped at the trunk – as if hit by a giant's hand.
A spokesman for the NRW Ministry of the Interior said that in addition to Paderborn and Lippstadt, no other places were known that had been hit similarly.
According to a spokesman for the district police, "a tornado ran across the city" and caused damage worth millions.
Meanwhile, the clean-up and security work continued in the East Westphalian city.
The police said the fire brigade, the Technical Relief Agency (THW) and other helpers were involved.
The police presence has also been significantly increased.
In view of the wind that was picking up again and again and many dangerous areas that were still unsecured, the police called on residents in the damaged areas to stay at home.
"Increased dangers from strong winds" can also be expected for Saturday.
The police, fire brigade and city administration want to comment on the extent of the damage in a press conference on Saturday morning.
The Paderborn police already spoke of a "swath of devastation".
Countless roofs were torn off, numerous trees uprooted.
Public transport was severely affected.
According to the fire department, Lippstadt was also badly hit by the storm.
The fire brigade announced that "a tornado probably passed through the North Rhine-Westphalian city in the afternoon".
A spokesman reported in the evening of "covered roofs, broken shop windows and many fallen trees across the city".
Injuries are "currently not known".
The storm depression also raged in Rhineland-Palatinate.
According to the police in Koblenz, a 38-year-old suffered an electric shock in Wittgert in the Westerwald on Friday evening in a friend's basement, which was flooded after a heavy thunderstorm.
The man fell after being electrocuted and probably hit his head.
Police say attempts at resuscitation were unsuccessful.
According to the police, there was “extreme” hail with hailstones with a diameter of around five centimeters in Andernach and Neuwied.
Several dozen cars were badly damaged.
Some of the windows of moving cars were smashed, the police said.

Several cars also remained in flooded underpasses.
Almost 400 operations in Nuremberg, Fürth and Erlangen
In the Bavarian Middle Franconia, almost 400 fire brigade operations were triggered in Nuremberg, Fürth and Erlangen as well as in the districts of Nürnberger Land, Fürth and Erlangen-Höchstadt.
The fire brigade came mainly because of flooded basements, uprooted trees and damaged house roofs, as they announced early Saturday morning.
The railway line was closed between Neuhaus and Hersbruck because trees blocked the tracks.
Trees fell into a power line in Nuremberg-Wetzendorf.
The troubleshooter then shut down the line to remove the tree.
When a wooden hut collapsed, 14 people were injured in the Roth district, including several children.
A 37-year-old woman was flown to a clinic with serious injuries, a police spokeswoman said.
The accident happened on Friday evening in Spalt near the Großer Brombachsee.
According to the police spokeswoman, several vacationers had sought shelter in the approximately 85-square-meter hut in view of the looming storm.
For an unknown reason, it then tipped to the side and collapsed.

Deutsche Bahn announced that the storm could cause delays and train cancellations in parts of Germany.
Several stops were canceled on the ICE and IC connections between Cologne, Wuppertal, Dortmund and Hamm, and the route between Hamm and Kassel-Wilhelmshöhe on the ICE and IC connections between Cologne, Hamm and Kassel-Wilhelmshöhe could not be used.
