I am noticing the same thing. It was there earlier today after updating to iOS8. But it's gone now. I have a feeling it's a bug.
I just hard reset the phone and it is showing up again. Looks like it's a bug.
I've found a few of these already. SwiftKey doesn't always get activated and defaults to the Quicktype (default Apple Keyboard) sometimes, even though I had selected SwiftKey in previous sessions of a particular app.
no weather since my update yesterday. reboots & resets did nothing. all location settings seem right.
I've never seen Weather since updating a 5, a 5s and an iPod5 to iOS yesterday. All settings seem correct.
I vote for bug. Hopefully fixed in 8.01
I would use the Yahoo Weather! app widgit except that when I let it use my current location, it never stops looking for location and sucks my battery dry.
Having the same issue since updating to 8.0.2 at 1 am last night.
I seem to have no options for the stock weather app anywhere!
