Snow plow drivers were busy clearing roads early Monday after a snowy weekend, but police reported no trouble on Region interstates.
As much as 4 inches of new snow was reported Monday morning in Portage and Merrillville, and some parts of the Region saw as much as 6.5 inches during the weekend.
But the worst may be yet to come.
Temperatures likely will become increasingly colder this week, with the most frigid period between Wednesday night and Thursday night. Wind chill temperatures could drop to minus 20 degrees during that period, according to the National Weather Service.
Highs in the 20s are expected Monday and Tuesday. Temperatures could drop from a high in the teens Wednesday to below zero overnight into Thursday, when highs are predicted to be in the single digits, the weather service said.
Temperatures this week in LaPorte County are expected to be slightly warmer than Lake, Porter, Newton and Jasper counties.
Snow could return across all of Northwest Indiana by Friday.
