As west winds diminish, clouds will gradually thin out this morning over northeast
Illinois. The resulting sunshine may be the last Chicagoans experience for some time. The
southern tip of cool Canadian high pressure will linger the next few days -- but
cloudiness and precipitation (mainly light rain) will spread over the area from the south as
low pressure tracks east along the Ohio River Valley. On Friday, a large low pressure
system over the Great Lakes will pull arctic air into the Midwest. Strong winds, freezing
temperatures and frequent snow showers are expected in Chicago later Friday and all day
Saturday.
HEAVY SNOW ACROSS NORTH MICHIGAN
With northwest winds whipping across Lake Superior, Winter Storm Advisories for heavy
snow were issued for Upper Michigan and northern Lower Michigan last night and this
morning. In Upper Michigan, Shingleton had 9 inches on the ground by 6 p.m. Sunday.
One to two inches were expected in southwestern Lower Michigan.
