For what it's worth, Jared, I'm in your same general area. I've been here for 16 years now and the last couple of years have been much warmer than when we first moved here and I've been able to plant out much earlier. And that's not to disagree with what others have said. Heh, I still remember that year when it was so nice and warm in May and I moved everything out of my greenhouse onto outside racks. The very next day, we had a torrential hail storm. I got drenched and beaten to a pulp trying to cover my poor little plants!
But if you're starting from seed, it's probably safe to try some of the cold weather crops like spinach and others that won't necessarily be damaged by frost. Or hail. Or snow.
Gardening is as close to gambling as I get.
