Solar Cooking on a Mostly Cloudy Day

We get real excited about the rain in Arizona. We drop whatever it is we're doing and run to the windows to watch it. A week of rain, like this past one, is almost unheard of. It turns out it's also unwelcome. After a few days of intermittent showers and a massive storm on Thursday we had had enough. By Friday, another gray, cold, and wet day, we wanted our sun back. Today that wish was half granted. The sky was pretty much 50/50 between clouds and clear. I didn't want to risk wasting any food so I scrubbed a few russet potatoes, popped them in the Sun Oven, and called it a day.
