Areas south of Fort Wayne may see less snow today than in Allen County and points north and west, but all will share the dangerous below-zero temperatures to follow, the National Weather Service said.
The agency's winter storm warning remains in effect through 1 a.m. Monday, with a wind-chill warning from then until 8 p.m. Tuesday, the weather service said shortly before 5 a.m.
For the northern counties, it said 8 to 14 inches of snow are expected, becoming heavy by late morning or early afternoon. That forecast covers the Indiana counties of Allen, DeKalb, Kosciusko, LaGrange, Noble, Steuben, Wabash, Wells and Whitley, as well as Defiance, Paulding and Williams in Ohio.
Gusty northwest winds will develop early this afternoon and increase to 20 to 30 mph by this evening, with gusts to 35 mph at times, the weather service said. It said that would cause significant blowing and drifting snow tonight into Monday and producw near white-out blizzard conditions at times.
Lows tonight will be between 7 below zero and 20 below zero, the weather service said, with deadly wind chills between 30 below zero and 45 below zero expected tonight through Tuesday.
But for Adams County, Ind., and Van Wert County, Ohio, it said snow accumulations of 6 to 10 inches now are expected, but "these amounts could be reduced if sleet and rain mixes with the snow."
Low temperatures in those counties tonight are expected to be between 5 below and 15 below zero, the weather service said, but the same deadly wind chills are expected of 30 below to 45 below zero from tonight through Tuesday.
