.SYNOPSIS...

Areas of dense marine fog are expected through this evening across
southwestern portions of Lake Michigan. Breezy northeasterly winds
are shifting to become northerly as low pressure of 29.7 inches
moves just south of the southern tip of the lake this afternoon
and into northern central Indiana tonight. Winds will slowly
diminish through Friday.

Friday night, southwesterly winds will increase ahead of a
developing low pressure around 29.5 inches in central Canada. This
low will deepen to 29.3 inches as it crosses southern Ontario on
Saturday, with breezy southwest winds shifting to northwesterly as
the associated cold front pushes southward across the lake. Gusts
approaching 30 knots are expected Saturday through Monday as
northwesterly winds continue.
