Forecaster Adam Hartman (

For this forecast, I looked at the model foretasted precipitation amounts form both the GFSHD and the NAM20. I also looked at the critical lines for these two models to help determine the location of the freezing rain and line where snow was going to fall. Locally over the Lafayette region, the snow gradients are going to be very pack due to the warmer air being pushed up further. This is the reason for the tilt in the contours. The northern section of Indiana was foretasted to get 0.9 inches of rain. I was equating that to 10 inches of snow since this will be a wet snow that falls due to the warmth associated. A widespread 4 inches is expected for most of Northern Indiana with higher totals towards the northwest. I am expecting Indianapolis to get about 2 inches with some freezing rain and rain mixing in.
