Cool spring weather is a great time to plant peas, lettuce, spinach, cilantro, cabbage, onions, radishes, carrots, beets, arugula, and potatoes. Most leafy vegetables or root vegetables can be planted 8 weeks or more before your last average frost date.
Early spring is also a great time to plant fruit trees, berry bushes, strawberries and most other fruiting plants.
Even if you get some snow all these plants should come through it just fine.
Arugula, cabbage, and onions in my portable 2' x 2' Square Foot Garden. I take this garden with me to Square Foot Gardening classes.

All of these planted in March, made it through at least two snows and some rain just fine.
Peas, spinach, lettuce, arugula, and cilantro can also be planted about 6 weeks before the first fall frost. As weather begins to cool in the fall, temperatures are again at the levels these plants prefer and it is likely you will be able to harvest a fall crop.
