It’s not going to look much different from this morning. There is a hint that the *heaviest* snow may fall farther north than previous expectations, so I’m now saying “8-12” for Lafayette and South Bend as well as most of central Indiana. If you are in Columbus or Greensburg it may be right at 8. Lucky you! Six inches could accumulate as far south as Evansville.
Snow will move into central Indiana after midnight. Heaviest snow will fall from roughly 7am-7pm. Accumulating snow should be gone by late evening.
Regardless if you get 8 inches or 10 – this will be some of the worst winter weather in several years, with the one-two punch of winds increasing later Sunday afternoon. Expect gusts of 30 mph, with blowing and drifting snow.
Bitterly cold air will begin moving in. Sunday temps will start in the upper 20s in the morning and fall to about 20 by 6pm. By 9pm the air temps will fall to the teens, and the wind chills will go below zero – where they will remain until Wednesday afternoon.
By Monday morning the temperature will have fallen to between 10 and 15 below zero and REMAIN THERE all day, bottoming out to around 20 below by Tuesday morning. Wind chills will run 30-45 below zero at times Monday and Tuesday.
