If you want the Sense clock/weather widget, there is one app available in the market (costs $1.99) called LP Sense skin + Clock, designed to be used with Launcher Pro. It doesn't give you the weather animations (ie: wiper when it is raining), and when you click on the weather preview, it looks different, but I tell you what, other than that, it is a dead ringer for the Sense clock app!
If you don't care if it looks exactly the same, there is a free app called Sense Analog Clock Widget Dark, which looks somewhat similar.
Enjoy!
