We have had a couple of claps of thunder here in Ocean Reef, but no real precip - has been somewhat light. I suspect some of the precip we see on the radar around Ocean Reef, anyway, may be virga?

EDIT: and just as I press submit, it starts raining steadily - go figure...

It disappeared for a bit (rain obscured it), then it was visible again south of me.

Had a few nice claps of thunder and some lightning, light rain. Looking north there were some mammatus clouds.
