100 is pushing it long term. However they should be able to handle one day of it - especially if you have them shaded during the really hot part of the day.
ventricosa and sanguinea are technically highlanders, though, so you want to avoid more than a day or two of those temps. They can take heat, like temps in the low to mid 90's, for a couple of days....and PROBABLY will be ok at 100, but I personally wouldn't push it.
Judith Finn, while it looks like a highlander based on it's parrents, I find grows better as a lowlander, so I wouldn't worry about that one.
