@abasket - you should be able to plant peas and carrots and cool weather greens already. Peas can sprout on warmer days and they don’t mind a little snow if it comes.
I had arugula in MD once and we got hit with 2+ feet of snow. When it melted, the arugula looked like it had been ironed flat against the ground. I wish I had gone out every day and snapped a photo. It slowly bounced back and grew just fine. Not as sharp as hot weather would have made it, but still plenty sharp and tasty!
