Late on the 18th of January, an intense lake effect snow band set up over Lake Michigan and into La Porte County, IN. The lake effect snow band had a plethora of mesovortices embedded within it, which helped contribute to snow rates of 2-3" per hour. By the evening of the 19th, La Porte and Michigan City both had over two feet of snow! The lake effect snow band gradually shifted west, dropping 8-12" in parts of Berrien County, MI and St Joseph County, IN as well. A 30 mile stretch of the Indiana Toll Road had to be closed by the Indiana State Police on January 19th due to a 5-10 car pileup. Portions of I-94 near Michigan City, IN had traffic backed up for several hours due to numerous crashes and slide offs.


The La Porte Cooperative Observer station measured 21.9" of snow for January 19th. This is a record 1-day snowfall total for this site. The previous record was 19.5" on January 26, 1978, during the Blizzard of 1978. Records for this station go back to 1948.
