Signs That Fall Is Ending

In the spring and fall you hear the geese as they pass above in giant V's.  Usually I'm not in a position to get a good shot.  The other day I was in a position to get a shot that at least had the whole formation in it.

Today's bike ride brought me past a few puddles that had frozen in the cooler nights we've had the last couple of days.  This is east Anchorage where temperatures can be 10 - 15˚ F cooler than more western locations. 

And then there was this interesting cloud formation while I was waiting for the light to change.  Looking at a google page of clouds, I found Genus cirrocummulus.  It's not a perfect match, but the closest I could see.  Anyone know?

Here's the Wikipedia description and photo.  Do you see a similarity?  The page has lots, lots more clouds.

Genus cirrocumulus

A large field of cirrocumulus stratiformis

Cirrus fibratus radiatus
A A large field of cirrocumulus clouds in a blue sky, beginning to merge near the upper left.
Wikipedia cites Typhoonchaser  for this shot
Abbreviation: Cc[11][2]
Clouds of the genus cirrocumulus form when moist air at high tropospheric altitude reaches saturation, creating ice crystals or supercooled water droplets. Limited convective instability at the cloud level gives the cloud a rolled or rippled appearance. Despite the lack of a strato- prefix, cirrocumulus is physically more closely related to stratocumulus than the more freely convective cumulus genus.[12
