Started the PCT in the first week of May of 2004, a real light snow pack year. Each year can be vastly different so wait till the last few weeks to decide what gear you'll need and what gear to send ahead.
Best advice I took was from Lynne Wheldon who said to get a tan before hitting the trail. I'm also from the northeast and I had six sessions (5-7 minutes each) in tanning booths, not tanning beds, for two weeks before heading west. It made for a relatively easy transition into desert hiking in record high temperatures.
The wind, aspecially the Santa Anna wind, can chill you to the bone even in moderate temperatures and make forward progress slow at times . Make sure you're prepared.
Looks like your starting a few days after the ADZPCTKO party ends, April 27-29. The main pack can really deplete water caches in the desert section. Don't count on getting all the water you need from water caches when you're so close behing the main pack.
Good luck!
