Very light snow will continue to fall until midnight Monday night, according to the National Weather Service at Romeoville-Chicago.

After midnight, a band of lake effect snow will shift more into Northwest Indiana continuing into the day Tuesday morning. The National Weather Service said it could become heavy at times especially in portions of LaPorte and Porter counties.

The heaviest snow time frame appears to be between 8 or 9 a.m. where there could be periods of heavy snow showers. Snow showers also are likely after noon. The day is expected to be mostly cloudy, with a high near 23. West wind around 10 mph, with gusts as high as 20 mph.

Lake County will see some snow but the bulk of it will be east of Lake County in Porter and LaPorte counties with a winter storm watch in effect for Porter County and eastward.

A spokesman at the National Weather Service said Monday evening they were waiting to see how heavy the snow would be eastward.

On Monday, there was a winter weather advisory for Porter County and LaPorte County that ended about 6 p.m. in LaPorte County, with an additional inch of snow in Porter and possibly 1 to 2 inches in LaPorte County through late Monday. 

Snowfall Monday morning led to multiple slide-offs and spin-outs on Northwest Indiana roads. Indiana State Police cautioned drivers should slow down and allow extra time.

Some westbound South Shore Line commuter trains were delayed early Monday because of damage to overhead lines late Sunday near the Dune Park station, a Northern Indiana Commuter Transportation District spokeswoman said.

Crews worked overnight to repair the equipment. NICTD had not yet determined if weather may have caused the equipment problem.

Snowstorms Sunday into Monday morning dropped 1 to 3 inches of new snow in communities across Northwest Indiana, according to data posted at the Community Collaborative Rain, Hail and Snow Network's website. As much as 3.7 inches of new snow was reported Monday morning in LaPorte, up to 2.5 inches in Crown Point and 2.6 inches in Hebron.

Cedar Lake advised residents that vehicles must be removed from roads after 2 inches of snow and cannot be returned until after roads are cleared.

Monday's snowfall may be just a prelude to larger totals Tuesday.
