That's a pile of hail that collected off a spot in the roof where things come together.
It's cold enough that it had not all melted after quite a few hours. Mostly, though, it's just a bit rainy and cool. Quite nice, really. My kind of weather.
I know other places have it rough, but so far I am quite happy with Vancouver weather.
Update: about 12 hours later, here's what that pile of hail looked like:
Yes, it's a bit smaller, but it was still there. It survived overnight.
So, yeah... it's been pretty cool here.
