Indiana residents should prepare for a mixed bag of weather conditions as the weekend approaches. Northern and central Indiana will experience sunny and calm weather for much of the upcoming week, with temperatures gradually climbing from the upper 60s today to the low 80s by midweek. However, overnight lows are expected to dip into the 40s across a wide swath of the state, including major cities such as Fort Wayne, Indianapolis, Lafayette, Muncie, and Kokomo.
