Advice needed on seedlings-boiling hot temps now; very cold last week, and cold expected Thursday

My seedlings were ready to start hardening off early last week, but it was extremely cold (I'm in Eastern PA). I started the process 5 days ago, during which time it got hot (Mid-90's). They HAVE to go in the ground ASAP, but now the weather will drop to the low 50's in the day, high 40's at night, and rain. How should I proceed? TIA.

Hi. I started seedlings 4 weeks ago. They were in my 55 degree garage for the first 2.5 weeks (heat mat at 75 until germination). I'm pretty sure that was too cold. I turned the garage up to 65 about 10 days ago. They still look very small and the purple color on most bothers me. I'd like to start hardening off in 2 weeks tops. I bought a PPAR meter, and it measures 750 dead center and 550 or so around the edges. I use a Vipar Spectra light. Oscillating fan on 12 hrs/day. Do I stand a chance??
