Don't let Thursday's blue skies fool you. Snow is on the way.
A lake-effect snow watch goes into effect Friday afternoon for Cook and Will counties in Illinois and Lake and Porter counties in Northwest Indiana.
Snow showers are expected to develop early Friday afternoon and continue into the evening with likely at least a few inches of accumulation. Some places may see up to six inches of snow.
Drivers should be prepared for perhaps a slippery afternoon commute Friday in areas near Lake Michigan and in the south suburbs.
Conditions will turn windy and colder Friday afternoon, with temperatures falling from the 30s to the 20s by evening.
The snow-maker moves east by Saturday afternoon.
