(WXYZ) - Whether or not schools in southeast Michigan will be in session in spite of the cold is a tough call for Wednesday.
Temperatures Tuesday afternoon climbed a little higher than we'd expected, which helps, but once we lose the January sunshine, they will tumble again tonight.
We're expecting lows tonight to range from about 9 below to 1 below in most areas. At 7 a.m. Wednesday, most areas should be between 0 and five below with a wind of 10 to 15 miles per hour.
This produces a wind chill near 20 below. Of course, it could vary 5 degrees either side of that figure, and that's the problem. Many schools use 20 below wind chill readings as an APPROXIMATE cut-off for deciding if it's safe to have school. So, to recap, here's what we know:
*A Wind Chill Advisory will be in effect until 10 a.m. Wednesday
*Wind Chill should be near -20 at 7 a.m. Wednesday
*Both wind and temperatures will increase during the day Wednesday
*Temperatures will not be an issue for possible closings Thursday or Friday
My gut feeling is that we will not have the mass closings that we had Tuesday, but some districts will decide that the best thing to do is to keep school closed for one more day.
My advice to students (including my own kids) is to get their homework done. My advice to parents is to prepare for both possibilities and to keep checking with Channel 7 and WXYZ.COM for when decisions are made.
