A Cloud 'Blob' ~ Skywatch Friday

I found this weird cloud (photos 1 & 3) in my neighbourhood the other day. I stopped to take a couple photos but they didn't turn out well. I've never seen such a cloud before. Does anyone know what it's called?

It was a beautiful, sunny day and still quite warm. I understand we're supposed to get rain on the weekend, possibly even Friday night.   I can't complain about our weather as it's been quite nice.

Thanks for stopping by my Skywatch Friday post. Have a wonderful weekend.
