The winter of 2011-2012:
I'm sure most of you will agree that the past winter was quite unusual. There were quite a few underlying reasons for this. However, the primary reason was the position of the polar jet stream. Below are a couple of images of the jet. The first image shows how the polar jet behaves on average during the winter. The second shows how the polar jet more or less looked like during the winter of 2011-2012; outside a couple of dips south, it more or less stayed in this configuration for most of the winter.
The jet stream during the summer:
Meteorological Summer is almost here. During mid to late spring temperature and precipitation patterns start to get locked in. As I said above, the jet plays a very important role in how the summer season will behave. During a typical summer the polar jet will move back to the north. Image 3 shows how the jet looks on average during the summer.

The 2012 hurricane season:
The 2010 Atlantic hurricane season was the third most active Atlantic hurricane season on record, with 21 tropical cyclones, 19 tropical storms, 12 hurricanes, and 5 major hurricanes.
Remember, while the stats show a much lower chance for a season like last year; it only takes one landfalling hurricane in your region to make things terrible. So please take heed of any hurricane watches or warnings.
