The Midwest is bracing for an uncharacteristic heat wave this Sunday, with temperatures expected to soar into the 80s and 90s. Several cities, including Minneapolis, Chicago, and Grand Rapids, are at risk of breaking daily and even monthly October temperature records. While the heat is significant, humidity levels will remain relatively low, offering some relief from the stickiness often associated with summer heat. However, this combination of heat and low humidity, coupled with ongoing drought conditions, heightened evaporation rates, and gusty winds, creates an elevated risk of wildfires across the region.
