Could be frost Jason.....esp if you left door open. Could also be strong sun. Young tomato plants are sensitive things. Or have they dried out?
you could drape fleece over them or,suspend it above them at night time and during hot times until more mature.
i once lost a whole batch of tomato plants .....in my naivety I used too much dried cow manure and the fumes during a hot day destroyed them. Gardening is a learning curve.
