Here are some screen shots form Andrew Nechiporuk on Twitter of new looks for how Google shows weather results in Google search. You can see this one has a large graphic showing it is cold outside and then shows the weather by hour below. Both look different from the normal weather knowledge panel.
I feel like I have seen this test before, but maybe on the Google App and not using my iPhone's Safari browser?
Here are more screen shots:
Looks like Google is testing weather rich snippets.

Two different layouts within just a couple of hours.
The second one is significantly longer, pushing #1 spot far down the SERP. @rustybrick, you might be interested in looking at it. pic.twitter.com/Lr8qEWzBm3
