Snow Squalls Setting Up, and A New Years Storm!

This snow squall graphic is the closest to what I think will setup within the next two days. The areas colored in white could receive upwards of 15 centimeters of snow. The areas colored in brown could receive a dusting.

If you notice at the top left hand corner of this blog, there is a box labeled "NAO". NAO stands for North Atlantic Oscillation, in which it uses sea pressures to determine the upcoming patterns. This tool predicts the patterns for each month, and if it is in the negative range below the line, then that usually says that the North Atlantic will receive cool temperatures and much precipitation. If it is above the line, then that signals warm temperatures and possibly little precipitation. Now it is a little more complicated then that, however I think you now get the general picture of how the NAO works.

The NAO for January 1, 2010 has the oscillation in the negatives. Quite negative as you can see. Now based on what I told you in the last paragraph, this means snow. Weather models for January 1, 2010 has some type of disturbance from the south coming up the East Coast while at the same time, yet another disturbance is coming from the West, also heading towards the disturbance on the East Coast. If these two disturbances meet and intensify, then we have a winter storm. A winter storm that would affect Southern Ontario. Now it is still early to trust the models predictions, but I can see that some of these key components are adding up for a New Years Day storm. Stay tune for further updates.
