Wisconsin On Track For Warmest Winter Ever

Saturday, February 17th, 2024 -- 8:15 AM

Wisconsin is on track to have its warmest winter ever recorded, with January temperatures 8.5 degrees warmer than average.

December was the warmest ever recorded in Wisconsin. February has been 19 degrees warmer than usual so far. The state also saw its first recorded February tornado last week. But experts told Wisconsin Public Radio we won’t know the full extent of the season’s economic and ecological impact for several more weeks. The National Oceanic and Atmospheric Administration reported Wisconsin’s January temperatures were the second highest anomaly of any state, behind only Minnesota. That’s in part because of El Niño, which develops when sea surface temperatures are warmer than average for several months. As a result, there tends to be less snow. Steve Vavrus is the state’s climatologist. He said the weather is already causing economic impact, especially on the tourism industry in northern Wisconsin. “They depend on snow and ice for skiing and skating and ice fishing and so forth,” Vavrus said.  “There’s been closed snowmobile trails. There’s been winter festivals that have been canceled, unsafe ice conditions for fishing and so on.” It will take several more weeks to know the extent of ecological impacts, Vavrus said. 

“One of the concerns of a warm winter is that plants bud and bloom prematurely, and then they get zapped when the weather turns back to cold. And that could well happen this year depending on what happens the rest of the next month or two,” he said. Plants respond to the temperature, not the calendar. In the spring of 2012, temperatures reached the 80s in Wisconsin, Vavrus said, and leaves and flowers started blooming. An April freeze then wiped out much of the crop of the state’s fruit industry. “I’m holding my breath on whether we’re gonna see a false spring with its economic and ecological repercussions this year,” Vavrus said.
