The rule of thumb is the heavy snow will fall about 150 miles north of the surface low. This places a axis of heavy snow just north of Indianapolis – through the heart of the state. The change over to snow is expected to come from north to south – here in the city after midnight (around 2AM). A heavy. wet snow will fall through sunrise. Snowfall amounts could range from nothing to 9″! The fickle track will be monitored – any adjustments in the track will result in a shift in snowfall amounts.
