DETROIT – Some of us are getting late afternoon breaks of sunshine, but any partial clearing should last only for part of Monday night, as clouds will increase once again sometime after midnight. Lows will be in the low 30s, or 0 to minus 1 degree Celsius for our Canadian friends across the river. Southwest winds will shift to the northeast later Monday night, at 5 to 10 mph.
Tuesday morning's rush hour will be dry, but that might not be the case for the afternoon commute, as a storm system moving northeast from the Gulf states (but passing far southeast of us) will still spread some moisture into southeast Michigan.

The models differ a bit as to how much rain we’ll get, so at this point, plan for at least a chance of rain midday through early evening. I’ll have to monitor to see if this will be a steady rain or more of a drizzly, off-and-on light rain.
Highs should be near 40 degrees (4-5 degrees Celsius), but don’t get used to it. It’ll be a long time before we see that temperature again. East winds will blow at 8 to 13 mph.
Tuesday’s sunrise is at 7:48 a.m., and Tuesday’s sunset is at 5:01 p.m.
Any lingering Tuesday evening rain may mix with a few wet snowflakes in our North Zone, but all precipitation should taper off rather quickly as the evening progresses. Lows by Wednesday morning will be in the upper 20s (minus 1 to minus 2 degrees Celsius).
It will be mostly cloudy and perhaps a little breezy on Wednesday, with highs in the mid-30s (1-2 degrees Celsius). Our Arctic cold front will have crossed the area overnight Tuesday, but the core of our coldest winter air mass of the young season thus far won’t arrive until Wednesday night, when it will be breezy and colder, with lows in the mid-20s (minus 4 degrees Celsius).
Thursday and Friday will be windy and cold, with snow showers possible. It appears that Thursday might be the better day for organized lake-effect snow bands, but I’ll keep a close eye on this and update you through the week.
Highs will be near 30 degrees (minus 1 degree Celsius), and lows in the upper teens to low 20s (minus 5 to minus 7 degrees Celsius). Wind chills on these days will be in the teens (minus 8 to minus 11 degrees Celsius), so make sure that children in particular are ready if they’ll be standing out at the bus stops or walking to and from school.
It will be mostly cloudy on Saturday as we temporarily shut off the snow shower machine, with highs again near 30 degrees (minus 1 degree Celsius).
Snow is possible again on Sunday, and there is a tremendous amount of spread among the computer models about this system. It doesn’t appear to be a massive storm to get all worked up about (plus, it’s a weekend day, so your commute to work isn’t affected), but it still is snow.
I’ll watch these developments closely through the week. Regardless, Sunday highs in the mid-30s (2 degrees Celsius) along with upper air forecasts of sub-freezing temps aloft are strongly suggestive of this remaining all snow.
