More snow Wednesday ahead of arctic chill

3:00 PM Update: Snow continues through Wednesday afternoon. Latest model and radar trends show the highest snow totals will be south of US-30 ( Fig 3). Light lake effect snow could start-up overnight as temperatures drop into the single digits overnight. 

10:30 PM Update: Tuesday night's clipper system sped through Michiana dropping 1 to 2 inches before midnight. The next round could do the same, but our southern counties, along and south of US-30 could see the brunt of it with 1 to 2 inches Wednesday afternoon (Fig 3). Temperatures fall into Thursday.

4:30 PM Update: Light snow starts after 6 p.m. Tuesday evening, with most the area north of US-30 still seeing 1 to 3 inches of snow. The change in this forecast is that Lake Michigan could enhance snowfall in southwest Michigan where 2 to 4 inches could fall (Fig 2). This is why an Winter Weather Advisory was issued for Berrien, Cass and St. Joseph counties in Michigan. 

There will be a short break before another round of snow. The arctic air sweeps in Wednesday afternoon another 1"-2" could fall along and south of US-30 (Fig 3). 

The next round of weather won't compare, to the more than a foot most the area saw Sunday, but it will slow you're morning drive Wednesday and you'll at least need the broom to clear your sidewalk. 

Tuesday night a quick moving clipper system dives through Michiana. Snow will start after 7 p.m. with the heaviest snow around midnight, before ending around midday (Fig 1). Latest model runs have trended upwards but totals remain in the 1 to 3 inch range, with most the snow along or north of US-30. In the wake of this system another bout of cold arctic air.
