When do I need to protect a fruit tree from cold, and how do I do it?

We have several cherry trees and an apple tree in our back yard. Due to the very warm March we had (in Minnesota), they are all covered in flowers. In a few days, there is a chance of snow, and an overnight low of 26.

What do I need to do to protect them?

I saw When do I need to protect a fruit tree from cold, and how do I do it?, but I don't know if the difference between just starting to bud, and having flowers on them for a week or two is important.

My initial thought was to cover them with tarps if they aren't too big. I like the suggestion in the question you linked to about placing heaters under the tree as well.

A quick search found this site about protecting orange trees. It suggests keeping the ground near the tree wet and wrapping the trunk with cardboard or cloth.

This site has a fantastic suggestion - put Christmas lights on the trees and leave them on all night.

Those are some things to try. I think anything you can do to raise the temperature around the tree a little bit is good whether there are flowers on it or not.
