Support Why does my lock screen change to the weather?

view story

http://androidforums.com – I've noticed that in the mornings when I turn on my phone, it shows the weather and two buttons, I think one is called Forecast. It doesn't show my dock bar. The problem is that I have my lock screen set to show my contacts, not the weather. Once I unlock my phone and then re-lock it, then it works properly. Anyone know why it does this? Edit: I should add that this weather screen is not the same as the actual weather lock screen that you can set. This one is not full screen, but rather shows the weather in a box. (General)
