They have those high-low thermometers at farmtek.com and lots of other goodies too.
Go to menards and get some anchors that you drive down into the ground to hold that sucker down. If the frame is heavy duty enough to stand wind when tied down and not break. When I started out, I had a little tent thing like that and I put strapping over the top of it and drove anchors on each side. It eventually did blow away anyway though, but at least it waited until summer when I didn't really need it anyway. We get too much wind here, everything has to be pretty much hurricane rated. I couldn't get anything to stay over my veggie stand until I finally bought a metal carport, heavy duty and anchored it down to the ground with those anchors. We routinely get 45-50 mph winds from oct-june. Also cement blocks on those "skirts" of plastic will help, but the wind will rub holes in your plastic, so wrap them in old blankets, towels, or t-shirts first so that they're not so abrasive. I found a picture of it on webshots, I used this little sucker for a couple of years when I ran out of space, until the zipper quit working in the door. It was tight quarters when a customer wanted in there with me though!
