I am 50 miles south of you in Muskogee and I planted out 2weeks ago and have not covered them till tonight. 34degrees forcast here for tonight and that is too close for comfort. They have experienced no detrimental effects from being left out at 36 or 38 degree nighttime temps. While you will not see growth above ground, the roots are developing constantly and you will get fast growth when the temps reach 70s. I will probably cover tomorrow night also to be safe. I use weather underground for the most accurate forecast .Just type in your zipcode. I think you could plant out anytime after wednesday march 30th. If you wait too late the heat and humidity will effect the fruitset as it did mine last year. You want your plants to have lots of green tomatoes on them by mid May. Many varieties will not set fruit when the temps get above 90 to 95 degrees. Assure yourself the best chance of a good crop by planting as early as possible.
Just my thinking
