Final Prediction

The all-important question that will determine snow accumulations in Lake Orion tonight is...will we be dry-slotted? Dry-slotting occurs when dry air moves in behind the low pressure system, resulting in a break in snowfall. We probably need 4+" to get a snow day tomorrow, and as long as we don't get dry-slotted for an extended period of time, that will probably happen. This is a heavy, wet snow that will make rush-hour traffic tomorrow morning terrible, especially as there is probably a layer of slush under the snow. What I will say is that it is a tough call as to whether or not we in Lake Orion will get a snow day tomorrow, as we will probably be right on the edge of the extended dry-slotting. However, I think we manage to pick up around 4.5" of snow tonight for a storm total of around 6", which is probably good enough for a snow day tomorrow.

Therefore, my prediction is YES, we will get a snow day tomorrow. A tough first prediction to make for sure though, and I'm not just saying that so I have an excuse if we have school tomorrow. If we have school tomorrow, I will freely admit that I was wrong.


Here is my snow day chances map. What is the 50% line? It is the general snow day line. Areas to the N of the line have a greater than 50% chance of a snow day, and areas to the S of the line have a less than 50% chance of a snow day.
