INDIANAPOLIS - A storm system that dumped up to 6 inches of snow in central Indiana on Thursday is just the opening act for what could be a major storm system hitting the area this weekend.
Forecast models are showing the potential for significant snowfall accumulation across all of central Indiana on Sunday, followed by an Arctic blast, dropping temperatures to levels not seen in at least five years, maybe in up to 20 years.
The storm system has not yet taken shape, so it's very difficult to forecast storm totals at this point. A lot will depend on the strength of the storm and the track it takes.
However, it appears that some locations just to the north and west of the storm's track have the potential of receiving 10 inches or more of snow.
Central Indiana may or may not be in that area. The forecast will begin to come into clearer focus on Friday and Saturday as the storm system develops.
While snow is the main concern Sunday through early Monday, a shot of bitterly cold air will move in from Canada behind the storm system, bringing low temperatures not seen in central Indiana for several years.
"Actual temperatures could fall to 12 degrees below zero by Tuesday morning," StormTeam 6 meteorologist Ashley Brown said. "If so, this will be the coldest low since January 1994."
The low temperatures in Indianapolis hit 10 below zero in January 2009, and the low was -15 in January 1994.
Highs will be in the low single-digits, and wind chills could be in the -30 to -40 range.
StormTeam 6 meteorologist Todd Klaassen warned another snow system could move in Thursday.
