I protest! You can't be 5b and not be expecting anything lower than 50ºF! It's false advertising... or something.
I'm looking at 38/36ºF for Tuesday low here.

Never the less, you guys are pushing me into taking chances. When you have a 75ºF afternoon with 110ºF in the sun, you can't help thinking it's got to be OK. So I planted 3 of my June racers. 1@ Moskvich, Moskvich, Jr., and Yellow Bell -- all 60 days.
Here they are in my crowded and weedy 4'x4' bed. It a bit blurry but I planted them in the bare spots where the peas didn't come up. I need to thin the spinach in the near corner, big leaves are lettuce, and markers indicate carrot area with radishes to break up the crust. Most of the scattered little greens are cilantro, with some other stuff -- lamb's quarters, looks like carrots and some kind of crucifer -- could be Cauliflower or a Romanesco, and an apple seedling in the center of the far wall.
Tonight's low is 47/45ºF and tomorrow's is 41/39ºF. So the toms are wearing their 'caps.
