IOWA — A major pattern change now officially in the works is set to bring the warmest and potentially hottest temperatures of 2026 to Iowa, Illinois, Wisconsin, and Indiana starting as early as Friday, with 90 degree readings possible this weekend and into early next week — weeks ahead of the average date of June 4 for the region’s first 90 degree temperature of the year.
Forecasters note that the first 90 degree readings of the year have already occurred in May in three of the past four years, making an early 90 degree event far from unprecedented for this time of year.
