Somewhat Important Note:

Due to the popularity of the blog, I receive numerous Facebook requests before potential snowstorms. Although I am flattered that you want to follow me on Facebook, I would ask that you not friend request me unless you know me in real life. It's nothing personal, I've just decided I don't want too many friends on Facebook.

Thanks, John

Monday Afternoon - Tuesday Forecast

Two weak systems will induce surface low formation over Lower Michigan on Monday. This will bring an abrupt end to the nice weather we will receive tomorrow, and will likely provide the first widespread accumulating snow of the season for Southeast Michigan.

Chance of Snow: 100%
It definitely seems like this system will form to the west of us, and then track over us bringing precipitation. Although the precipitation will likely start off as rain on Monday Afternoon, it should quickly change over to snow.

Chance of a Snow Day: 5%
The main snowfall will come at a fairly good time - approximately between 5 and 11 p.m. Monday Night - for receiving a snow day. However, what remains to be seen is just how much snow may fall. At this time, I am thinking that the Lake Orion area will only receive 2-4" of snow due to two factors. 1) The precipitation will likely start off as rain. 2) This low pressure system isn't particularly strong. However, if later model runs show that the low pressure system may be stronger, or that temperatures will be colder resulting in an all snow event, then snowfall amounts and snow day chances will have to be adjusted upwards.

The Bottom Line: This storm will probably bring the first widespread snowfall accumulations of the season to Southeast Michigan. However, the snowfall amounts will likely remain low enough to only cause a messy commute Tuesday Morning, not snow days.
