Old man winter is maintaining his tight grip on the region and doesn't plan to let up for several days, with hazardous blowing snow, 6 inches of new accumulation and dangerously cold temperatures in the mix through Tuesday.

Area police on Friday said many roads remained partially snow-covered, slick and hazardous following the snow that blew through the region on Thursday. Intersections, ramps and bridges were particularly slick, police said.

Indiana State Police continued to respond to numerous slide-offs, spin-outs and crashes on expressways Friday. No serious injuries were reported.

Snow plows continued to work, trying to clear snow from the roads, but police said the blowing and drifting snow coupled with bitter cold temperatures made the job challenging.

Municipalities reminded residents of snow routes being in effect, which prohibit street parking after 2 inches of snowfall. Residents who do not remove their vehicles from the roads to allow plows to clear and treat the streets could face tickets.

Region residents woke up to below zero temperatures Friday, with the mercury dipping to 10 below zero and wind chills reaching 12 below zero, according to the National Weather Service. 

Temperatures are expected to reach just 15 on Saturday.

Forecasters are warning of blizzard-like conditions from blowing and drifting snow through Saturday morning, prompting a winter weather advisory by the National Weather Service.

The advisory is in effect for Cook, Will, Lake, Porter, Newton, Jasper and Benton counties through 9 a.m. Saturday. Winds are expected to increase to 20 to 25 mph with gusts up to 35 mph, creating dangerous blowing snow that could create zero visibility for motorists, forecasters said.

The blowing and drifting snow will be followed by new snowfall starting around 1 p.m. Saturday that is expected to dump at least 6 inches of new accumulation across Northwest Indiana.

Lake, Porter, LaPorte, Newton, Jasper and Benton counties are under a Winter Storm Watch from Saturday evening through 1 a.m. Monday.

David Beachler, a meteorologist with the National Weather Service, said the bulk of the snow is expected to fall overnight Saturday into Sunday morning before tapering off Sunday evening.

The snow will be accompanied by 15 to 25 mph winds which could cause blowing and drifting snow and low visibility for motorists, creating hazardous driving conditions.

Sunday will also bring the start of dangerously cold temperatures, with a low of 15 below zero and wind chills dipping to 30 below zero.

Monday's high temperature is expected to reach just 5 below zero with wind chills as low as 40 below zero.

Tuesday will only be slightly warmer, with a low of 7 below zero and a high of 1 below zero.

Wednesday may bring some relief with a high of 17.
