Tonight's Forecast

A weak low pressure system will track from Tennessee up to Cleveland by tomorrow morning. To the north of this system, snow is occurring. The snow is currently edging into SE Michigan, and should reach the Lake Orion area in around 3 hours. After the snow starts, it will quickly become heavy, with snowfall rates of up to an inch an hour occurring. Still though, I don't expect a snow day tomorrow. The snow will only fall for 6 hours or so, with total accumulations in the 3-6" range. 6" is usually a borderline snow day, but I honestly don't expect a snow day even if we get that much snow. This is because schools usually all call snow days at once. However, the schools that only get 3" of snow obviously won't call school, and therefore the few schools that actually get 6" of snow won't call school, for fear of backlash from being one of the only schools to close. I can think of a similar event from last year that resulted in us having around 6" of snow, but still not having a snow day. Here's the link:

I expect a similar event tonight, with a lot of people getting 3-4" of snow, a few people getting 5-6" of snow, and almost no one calling school. Therefore, my prediction is:

NO snow day tomorrow.

Here's my snow map for tomorrow:

Note that although Lake Orion is in the 3-6" zone, we are on the northern edge of that zone; therefore, I tend to think we will be closer to 3" of accumulation than 6" of accumulation.
