Captain,

Night time temperatures that are above 32F will halt the growth of a tomato plant. Damage will not occur as long as thee temperature is above 32F.
Many strains of tomato plants have been known to survive an overnight low of 30F but at that stage damage most likely will occur.

If your overnight lowest temperature was 36F you are safe, if you drop any further I would pay close attention.

In the 2013 season I dealt with three consecutive nights of temperatures hovering at 33F without covering.

The plants were just fine as it warmed to the mid eighties during the heat of the day.

I hope this helps you.
