text: when is the first snow predicted for indianapolis? the temperature in central indiana has been decreasing, but it does keep darting back up every now and then. i've heard many mentions of snow and know that it has lightly touched the north of the state already, but when is it expected in indianapolis? (source please) i am predicting about 2 more weeks (november 12-15) for indianapolis. i should clarify. this be a night time snow of about an inch and melt off the next day. just be careful driving early that morning.
