Brood V (5) 17-year cicadas have emerged, this spring of 2016, in Maryland, New York, Ohio, Pennsylvania, Virginia & West Virginia.
(7/4/16): It’s a wrap! I’m sure there are some periodical cicadas hanging on out there, but for the most part, the emergence should be over. I hope you had fun.
(6/26/16): By now you should see (and hear) sharp declines in cicada populations. They’ll be gone in most places by July 4th. You should start to see Flagging of tree limbs where the cicadas lay their eggs. This is a natural part of the process.

Gene Kritsky has updated his book “In Your Backyard: Periodical Cicadas“. It is available for the low price of $4.99 for Kindle and Kindle readers. Totally worth it.
About Brood V:
The cicada species that will emerge are Magicicada cassinii (Fisher, 1852), Magicicada septendecim (Linnaeus, 1758), and Magicicada septendecula Alexander and Moore, 1962. These periodical cicadas have a 17-year life cycle. The last time they emerged was 1999.
When: Generally speaking, these cicadas will begin to emerge when the soil 8″ beneath the ground reaches 64 degrees Fahrenheit. A nice, warm rain will often trigger an emergence. So, definitely May, but something might happen in April if we have a particularly hot spring.
Locations where they are likely to emerge:
This data comes from the Cicada Central Magicicada Database and other sources.
Although the cicadas will emerge in MD, NY, OH, PA, VA and WV, the area is limited and patchy. No Brood V cicadas for D.C., Cincinnati, or NYC (people have asked). Their range is closer to this map (with cicadas in the orange areas):
