A generic report for your ZIP code suggests that pointing SE toward West Palm Beach would be a good start... It also looks as if you may need to consider adding a High-VHF antenna if you want to have a chance at seeing the NBC and CBS affiliates, WPTV and WPEC.
Mounting outdoors, clear of obstructions is going to be vital if your conditions are similar to the generic report. If I was in a similar situations, I'd be considering a tower or at least a push up type mast... Going for above tree top level.
