Another major winter storm could move through South Central Indiana on Sunday night, but its exact timing and impact remain uncertain.
Meteorologists with the National Weather Service in Indianapolis are encouraging Hoosiers to be mindful of the forecast this weekend in preparation for what may come.
“There is just a lot of uncertainty right now in terms of how this is going to play out,” said Jason Puma with the NWS. “This is a developing situation, so people really need to be paying attention to the forecast and be willing to make adjustments to their plans as necessary to stay safe.”
Meteorologists say they are keeping a close eye on a system that will begin moving across Indiana from the west. The current forecast calls for its arrival late Sunday and continuing through the day on Monday.
Snow chances for this area right now, Puma said, are at 60-70%.
The chance for accumulating snow is likely — some areas of Indiana could see as much as another six inches of snow — but exactly where those heaviest bands will cross is still uncertain.
“But some areas, possibly your area, could see some shovel-worthy snow, several inches,” Puma said.
“But should that system track a little farther to the north or south, that would greatly impact how much snow different areas will receive. We are in the ‘stay-tuned’ phase of the forecast right now.”
Puma said should the NWS see that Knox County will be heavily impacted by this system — meaning six inches of accumulation or more is possible — they will likely issue a Winter Storm Warning, but that hasn’t been done yet.
“Because we just don’t have enough certainty right now in anything to start issuing that sort of thing,” he said.
One certainty, however, is the bitter cold temperatures that will enter the area.
Today is expected to be the warmest for awhile, reaching a high of 21 degrees.
Temperatures will then drop again overnight, reaching a low of just 11 degrees.
Sunday’s high will be around 18 degrees then it gets even colder on Monday, with a high expected of 13 degrees and a low around 7.
Tuesday, too, looks to be in the single digits.
As the cold weather bears down on much of southern Indiana, fire officials have warned against the dangers associated with secondary heating sources. Never leave them unattended, don’t place them near flammable materials like bedding or curtains, and now is the time to make sure all smoke and CO2 detectors are in working order.
Snow returns to the forecast, Puma said, on Wednesday and Thursday; currently there is a 30% and 50% chance of precipitation on those days respectively.
And while total snow accumulations remain uncertain, the one thing residents here can count on, Puma said, is for the cold to stick around, likely through the end of the month.
“We’re really in a cold period,” he said. “We’re not going to see temperatures even above freezing through at least next Friday. So whatever snow you do get as part of these two systems will stick around.
“You aren’t going to see any warm air for awhile to provide melting.”
