Just looked out my back door to see this - gee, we need it. Hope it pelts down and takes this sticky weather away.

Edit: To create this photo, I pasted two identical photos on top of each other in Elements. They had different EV levels by about 1.5. I had the darker one on top, and used the eraser tool to "uncover" the lighter one for the river and houses area. Interestingly, the "correct" matrix exposure was the darker of the two, probably because the dark cloud takes up so much area in the image.
