The month of December is climatologically the cloudiest month of the year, followed closely by November, and the week ahead in Chicago will live up to those benchmarks.
While there will be periods of sunshine, daytime as well as nighttime skies look to be predominantly cloudy the next seven days. A far-reaching overcast extending north from a low pressure system headed east up the Ohio Valley will hold over Chicago today, with a good chance of light rain also reaching into northeast Illinois. Some sunshine is possible Tuesday, but low pressure to the north will give longer periods of cloudiness and even a chance of light rain or wet snow Wednesday.
Friday may see the first vestiges of a low pressure system in the southern Plains that could have a major impact on the Midwest over the coming weekend. Some computer models project a colder Ohio Valley storm track that could result in accumulating snows in Chicago.
