Love this!
The first one is Big Weather. I reposted the link to it in this thread within the last week, so it shouldn't be too hard to find in a forum search. You'll need iWidgets to run it. There's also a Winterboard version if you prefer; that one isn't linked here, but a Google search on "Big Weather" widget iOS should turn it up, probably in a post on modmyi.
I went through the entire thread before I posted.
