Your plants should be fine. I've grown outdoors for several years here outside of Houston; and this year we've been over 95` since June. No problems. You don't mention if you have plates under your pots, if not, I recommend at least the plastic ones to help retain moisture. You can also use a fine mulch covering the soil. I just use the shredded paper from my shredder. One other point I might mention, is the direct sunlight they're getting; you only need 5 to 6 hours of direct sun light. You might experiment with this.

As for interrupting flowering? I seriously doubt it, just follow your watering/feeding regimen, and nature should take care of the rest. My plants have just started flowering, and should finish early Oct.

I manage to have two outdoor harvests a year however, because of the milder winters here in Houston. I have rooted clones by the first of Feb, and if the temps are to cold, I'll keep them under lights 20/4. Weather permitting, I'll take them outside for natural light <and electric bill savings>, and take them into the grow shed to finish the 20 hour light cycle each evening. By the middle of march, they're ready for full-time natural outside growth. The short springtime photo period throws them into flowering, with plenty of time to finish. Also, around the 1st of April, I'm starting my summer plants that finish in Oct.
If I can figure it out, I'll post some of this springs photos...
