INDIANAPOLIS - A winter storm warning will go into effect Sunday for central Indiana as a significant winter storm threatens to dump a foot or more of snow on parts of Indiana, before frigid temperatures settle in.
General accumulations of 6 to 10 inches are expected, but some areas could get a foot or more.
The storm is expected to move toward Indiana late in the day on Saturday, with the bulk of the snow falling on Sunday.
The storm track has shifted a bit north, which could mean lower accumulations in southern parts of central Indiana, where it is possible a wintry mix or even a period of rain could fall instead of snow.
A strengthening low-pressure system will swing by to the south and east of Indiana, funneling moisture and cold air into the state.
Snow should begin falling early Sunday morning and will be heavy at times through the day Sunday before tapering off late in the day.
"We're talking about snowfall rates of an inch per hour, possibly a little higher than that," according to StormTeam 6 Meteorologist Kyle Mounce.
More specific snow totals will depend on where you live and the track the storm takes. A swath of a foot or more of accumulation is possible in parts of central Indiana.
"Early estimates of snowfall, about 6-12 inches. I know that's a wide range, but as it moves in closer, we're going to lessen that range," StormTeam 6 meteorologist Ashley Brown said.
After the storm moves away, an Arctic air mass will build into Indiana, ushering in the coldest temperatures in central Indiana in 20 years.
The low temperature Tuesday morning is forecast at -15 degrees. That would match a low hit in January 1994.
Dangerous wind chills in the -30 to -40 range are expected.
