Oh and quite a snippet from the LOT AFD
By the time the lake effect ends on Monday, total snow amounts
will vary considerably across short distances. Where the snow
bands are most intense, total snow accumulations of 12 to 18
inches are expected with a ceiling of 2 to 4 feet if snow bands
end up stationary. This threat appears to be most pronounced
over Cook county, but may extend to Lake County Illinois and
Lake County Indiana, as well.
