Some cool forecast images:
This cloud got a mention on the weather forecast – Edgbaston Reservoir

When I saw this cloud I just thought it looked dramatic so I took a few photos. I saw the lightning flashing, but didn’t bother to try and get a photo of it.
However on the weather forecast they explained that we saw the lightning without hearing any thunder because the lightning stayed in the clouds and didn’t hit the ground.
They seemed to think it was an interesting meteorological phenemenon. Can’t remember where they said it was, but it’s somewhere out over the Black Country or beyond.
Weather Forecast

The good news: our beautiful rolling hills are vibrant, verdant and lush with emerald green grasses and wildflowers.
The bad news: more rain on the way – all week.
Looking across the Bay, from the edge of the Westpoint Slough in Redwood City, ~6 miles to the foothills in Union CIty.
This is a single RAW image tonemapped in Photomatix. The clouds have that overly dramatic "HDRish" look which I’m not totally enamored with.
It’s quite interesting how many different looks you can get from an image depending on the processing decisions…
