Narrative:

While being vectored by new york departure control in a modified B757; we found ourselves within a few miles of a weather buildup; since we were still trying to familiarize ourselves with the radar. We asked new york departure control for a slight deviation around the weather; and were told to 'stand by.' I assumed the controller was coordinating with another controller; so I turned to avoid the weather. The controller then approved our request and said; 'I see you're turning already.' I responded; 'I'm exercising captain's emergency authority;' to which he said; 'you have to tell me that;' to which we didn't respond. I guess I could have told the controller I was deviating before I turned; but I was taken aback; when he told us to stand by. That's not something you typically hear from departure control. I also felt it was pointless to say anything; because he was probably not listening to us. We deviated approximately 3 miles; and did not appear to cause any loss of aircraft separation.

Title: A B757 Captain exercised his command authority to deviate around weather during a NYC departure because ATC told him to standby when the weather encounter was becoming imminent. ATC complained that the pilot turned before talking.
