MERRILLVILLE — A cold snap remains the biggest weather threat for the remainder of the week, though parts of the Region could see more snow Thursday and Friday. 

Dangerously cold temperatures will persist Thursday with wind chill values as low as minus 5 in the morning and a high of 16 degrees. The Region could see less than a half inch of new snow accumulation Thursday night. 

Light snow will move across northern Illinois from 6 a.m. to 8 a.m. Thursday, spreading east-northeast to Lake and Porter counties. Stronger snow showers and lake-effect snow could be an issue for areas near the lake, according to the National Weather Service. 

Friday's forecast includes a chance of snow with wind chill values as low as minus 7 during the day. The greatest chance of snow was north of Interstate 80, but the NWS is closely monitoring lake-effect snow possibilities in Northwest Indiana.

Snow and cold could make roads slick and reduce visibility.

The New Year's Eve holiday will be mostly cloudy with a slight chance of snow and a high near 13 degrees. New Year's Day will be mostly sunny and cold with a high of 10 degrees.

Several communities have opened warming centers for residents in need.
