I just looked it up on FF and it says to keep temping at the same time as usual, you might see a little difference the first 2 days, then after that, they will be back to normal. It also says that you shouldn't adjust your temps, but make sure you note the circumstances. Your chart does look HOT!
Here is link if you are interested, it's under "TRAVEL" (more than 1/2 way down the page) HTH
