That’s quite a thunderstorm brewing!  I took this photo maybe 15 minutes ago, and the cloud has continued to explode in size.  It has a very noticeable “anvil top.”  Other clouds are now bursting up around it.  Good ol’ Texas late-Spring weather!

Just earlier this afternoon as I was driving to Mass, I was looking at the clouds and thinking it’s been a while since I saw a nice huge white cumulonimbus.

I think this one’s heading right for me.  Or will come pretty close in any case.
