INDIANAPOLIS - Editor's Note: An updated version of this story is here .
A winter storm watch has been issued for all of central Indiana for Sunday and early Monday as a strong late-season storm moves in.
A strong low-pressure system will sweep by to the south of the region Sunday, producing accumulating snow across central Indiana that is expected to begin early in the day and continue through Monday morning.
Storm Team 6 meteorologist Stephanie Ortmann said storm totals could be in the 5- to 9-inch range throughout most of central Indiana. Higher storm totals are possible in isolated areas.
Storm totals in the 3- to 6-inch range are expected in the Bloomington and Columbus areas.
This is a difficult storm to forecast because of the strength of the sun this time of year and uncertainty about how much rain will mix in to the precipitation in areas south of Indianapolis.
Snow and rain are expected to begin falling across southern locations early Sunday morning, and it will change over to snow as it fills in across the rest of the region in the afternoon and evening with the intensity of the snowfall increasing.
Most of the accumulation will start on grassy areas with a better potential for sticking on roadways into Sunday night.
Wind gusts of up to 30 mph are expected all day Sunday, causing low visibility at times and blowing snow.
Snow is expected to continue falling into Sunday night and into the early part of Monday.
