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

Final Snow Day Prediction

Well, here we go. My second possibility of why we might not get a snow day tomorrow may just happen. Here's that possibility (in the same form as I posted it yesterday).
Possibility Two: The storm slows down more than expected. The snow starts at around 4:00 a.m. Friday, and only 1-2" of snow is on the ground by 6:00 a.m. In this case we could have school, because our school got burned the last time they called a snow day on the expectation that significant snow accumulations would occur during the day. (That occurred on February 1st, 2008, when we were supposed to get 4-7" during the day and ended up only getting 3" of snow total.) If this possibility becomes reality, get ready for a long, long, long commute home Friday, as the bust potential on this storm is extremely low. However, I just don't think I can see our school not realizing that it would be extremely dangerous to send all students to school in near-whiteout conditions Friday Morning.





Well, guess what? The snow is now expected to start around, you guessed it, 4:00 a.m. tomorrow morning. It's always something that prevents the perfect snow day possibilities. However, I still think we'll have a snow day. This is because the heaviest snow will occur right during morning rush hour tomorrow. Whiteout conditions are possible, and roads will be horrible, as the road crews will not be able to keep up with the amount of snow that will fall.

Then, tomorrow afternoon, if we have school, we could easily end up snowed in, as drifts of well over a foot are possible because of 30+ mph wind gusts tomorrow. And my guess is that school officials don't want students driving to school in whiteout conditions, and that they also don't want students to be potentially snowed in after school tomorrow (although my guess is that if we had school, the school would do it's absolute best to make sure the the parking lots are as clear as possible after school). Therefore, my prediction is:

YES, we will have a snow day tomorrow.

Now, for the actual snow discussion:

A low pressure system will track from Eastern Colorado to Central Ohio. To the north and east of this low pressure system, a heavy precipitation shield will develop. Snow will start at around 4:00 a.m. Friday Morning, and quickly become heavy. Snowfall rates in excess of 1" per hour are likely much of Friday Morning. In fact, in the stronger bands, thundersnow and snowfall rates in excess of 2" per hour are possible. The thing that will limit snowfall accumulations is that this is a short-duration winter storm. Much of the snow will fall between 4:00 a.m. and noon tomorrow, with the snow tapering off to light snow showers tomorrow afternoon. Therefore, accumulations have been toned down from 8-12" to 6-10". However, I would expect our final total to be closer to 10" than 6".

Well, for your sake, I hope your right on the Snow day.

Otherwise a horde of angry High-schoolers may drive you out of Lake Orion.

what makes you so sure?

What makes me so sure? Well, to be honest, I'm less sure than I was during the school day today. However we're supposed to get over 6" of snow, and 6" is usually a good benchmark to use in my opinion when deciding on snow days or not. And also, although we won't have much snow on the ground for the commute into school, we will have 6-10" on the ground by the time school is over. And if you think about it, that's basically the same thing as if we were to get the storm tonight, and have 6-10" on the ground for the morning commute tomorrow. You still have 6-10" on the ground for one of the commutes. So, that's what makes me so sure.

And yes, to the 2nd poster, I am well aware that if we have school tomorrow this will be the most backlash I have gotten for a wrong prediction.
