The web site only gives status 2 hours or less before flight time. The telephone CSRs have no better information. This time frame does not allow customers to make a time-saving decision prior to leaving for the airport. Once you're at the airport, you can just look at the screen. I'd prefer more advance notice of delays than additional ways of getting no useful information.

P.S. Southwest's web site lists arrival and departure gates. If you are patient, you can match up gates and figure out where your departing aircraft is arriving from, then track down the status of that flight. This can provide a much more accurate indication of the ultimate delay than any initial optimistic projection. JetBlue's site lacks this capability because it does not show gate numbers.
