Snow will begin entering the state just after lunch time Tuesday. It will be around in the afternoon rush hours, and is likely to be heavy at times from 6pm – 3am, but lighter snow could linger through late morning Wednesday.
Heavy snow totals are most likely north of I-70. South/southeast of that corridor there will be some sleet and freezing rain mixed in.
The most common totals from Indy and the surrounding counties northward will be 6-9 inches. Areas from around Kokomo to Marion have the best chances at the highest totals.
The southern third of the state will generally see 3-7 inches.
Zionsville, Carmel, Fishers, Anderson, Muncie, Richmond, Kokomo
Lafayette, Indianapolis, Terre Haute, Greenwood, Avon, Greenfield
As expected, the Weather Service has upgraded the Watch to a Warning. The basic thinking is the same. The NWS is increasing its top range from 9 to 10 inches. I haven’t had a chance to examine the details yet.

Here you can get an idea of where NOAA’S HPC team thinks is the best chance for 6 inches or more of snow:
Here’s today’s video briefing, via indystar.com
Heavy snow is expected over much of the northern half of Indiana Tuesday afternoon through Wednesday morning. The National Weather Service has issued a Winter Storm Watch for the area you see illustrated on the chart.
Tuesday morning will be dry but the center of the storm should pull out of the Gulf Of Mexico Tuesday afternoon. Our heaviest snow will fall from late afternoon into evening, with snowfall rates up to an inch per hour. Snow could be mixed with sleet and freezing rain south of I-70, which will cut into snow totals.
Up to nine inches of snow may fall in the Watch area. The best chances for the bigger number will be north of Indianapolis. Winds could gust to 25 mph Tuesday night into Wednesday morning.
Snow should pull away by midday Wednesday.
