Heavy snow by Monday morning
Lake effect snow ends for the evening, and we stay dry until after midnight. Temperatures will be very cold, falling into the single digits. The next winter storm moves into the west half of Michiana by around 1 AM, and reaches the east half of Michiana by around 3 AM. Heavy snow will fall as we go into early Monday morning, with counties north of US 30 accumulation up to 3” by 7 AM. South of US 30 could see a trace to 2” by 7 AM. Snow keeps coming down throughout the morning, but as temps warm right above freezing, we could see some wintry mix by the mid-late morning, especially south of US 30. The heaviest snow and mix ends by around 4 PM. Some lake effect snow showers will be possible during the overnight and into Tuesday.
Overall, snow totals will range between 1” on the southern end of Michiana (Pulaski county) to 8-10” in the northern end (Berrien and Cass counties). Lake effect snow showers will add additional snowfall on Tuesday and Wednesday. The northwest winds will also bring in an ice-cold air mass for mid-week. Dangerous, life-threatening cold arrives on Wednesday, with highs in the negative teens. Wind chill values will be in the -30s to -40s, and frostbite will be possible within 5-10 minutes without proper winter gear. Wednesday could set a new record for the coldest day in Michiana history.
