Yes, if the communications uses a broken (lack of) key exchange. 
Stupidly, SSL only recently got improved to support 
perfect-forward-security, Safari and Internet Explorer don't really 
support it, and the PRISM companies, coincidentally, don't support it.

The good news is that a third of Firefox, Crome, and Opera SSL traffic 
uses good key exchange and not susceptible to passive snooping or 
after-the-fact decryption.

I didn't realize that SSL was so stupid.  Rather important technology 
was left out of SSL, even though it was already two years old at that 
point.  Grrr.

An interesting article on this:

The fact that the traffic with the PRISM companies allows this easy 
decryption underlines that efficiencies matter for the NSA.  Every 
monkey wrench helps...
