What's up with the weather?

We've had enough rain. That's always a good thing. How about some warm, sunny weather?! It was threatening to drop below 50 last night so I brought the basil in. It has been so darn cold that nothing seems to be growing. The bush beans are just hanging out, the tomato plants look blue, the peppers aren't even putting out flowers and the swiss chard hasn't grown in over a week. The roof, (my major growing area) is exposed to plenty of sun...if it would just come out! I'm trying some new planters this year, (Earth Boxes) for my veggies and can't wait to see things take off.
