Wisconsin Sees One Of Its Warmest Falls On Record
Warmest Fall In Southern Wisconsin Since 1931
This fall is one of the warmest on record across Wisconsin. According to the National Weather Service, this fall is the second warmest on record in southern Wisconsin and the third warmest on record in the northern part of the state.
In Milwaukee, the average temperature from September through November was 57.3 degrees. The average temperature in Madison was 54.5 degrees, according to NWS.
This fall is the warmest southern Wisconsin has seen since 1931, National Weather Service Meteorologist Sarah Marquardt said.
"The jet stream was situated pretty far to the north and that prevented cold air outbreaks from getting into our part of the state so that allowed for a pretty warm November and actually a pretty warm fall, as well," she said. That combined with La Niña may have caused a warmer than average autumn in Wisconsin, Marquardt added.
Meanwhile, northern Wisconsin and Minnesota saw the second warmest November on the books since the National Weather Service Office in Duluth began keeping records in 1874.
In Duluth, the average temperature for November was 40.2 degrees. National Weather Service Meteorologist Carol Christenson said November was the warmest they’ve seen since 1899.
"So it’s been very much, much warmer than normal. Like I said, 11 degrees above normal so it’s off the charts warm," Christenson said.
Overall, this fall is the third warmest on record for northern Wisconsin and Minnesota. The warmest fall on record was in 1963 when the average temperature was 49.8 degrees.
