School districts are beginning to announce decisions about classes on Friday ahead of the winter weather expected.

Here is the timeline of when to expect snow, sleet and a return to seasonal temperatures. The singer, model and daughter of Michael Jackson wrote that being "thankful would be a poor euphemism." Snow is on the way!

The winter weather advisory takes effect at 6 a.m. Thursday. Forecasters say 2-4 inches of snow could fall, with some sleet mixed in at the outset of the storm.
