And I want to add that tobacco is good down to 28.5°F. I don't recommend pushing your luck, but if all the forecast says, and if you trust said forecast in its relevance to your specific property, 32°, I wouldn't panic.
My forecast called for 25° a couple weeks ago so I picked nearly everything. It only hit 28°, and it's done so multiple times since then, and the small bits of tobacco which are still out there have zero damage.
