How do you workout in this?

Well, I was here during the coldest week they had in January and this next week is going to be a doozy in the opposite direction! :)
Monday        97F/38C
Tuesday       101F/39C
Wednesday  106F/41C
Thursday      109F/43C
Friday           111F/44C

Do you think this heat will burn more calories?
