I'm just north of you. Planted around May 1st and we've got a few flowers (started a few weeks ago). Farmer's Almanac gives the last frost dates as the end of April. Been using that as a guidepost for the last few years with no issues.
I just wait until its above 50 degrees plus every night, to be sure, and I usually get a shit ton of Tomatoes. I never had a lot of luck planting before mid- May but I haven't done that for some time.
