The National Weather Service has issued a Winter Weather Advisory in effect until 7 p.m. on Thursday, Feb. 20.

The lake effect snow continues through Thursday afternoon. This is when 3 to 6 inches of accumulation is expected under the band of snow. As the band wobbles from west to east at times, areas right around the band will see lower totals of 1-3″. There will likely be a pretty sharp cutoff between where the snow is heavy and where there’s almost no snow falling. Keep that in mind for traveling tonight and tomorrow because some areas will be completely fine for travel and other spots may have whiteout conditions at times. The main focus for the heaviest snow will be Berrien County, far northern LaPorte County, St Joseph County, Cass County and possibly far western Elkhart County.

It looks like our snow chances come down by the end of the week. Temperatures begin to moderate at that point, too. Highs will climb back into the 30s by the weekend.
