Aircraft Y was being worked by the STN controller on a 160 heading and clipped the corner of my airspace on final (ARM sector); right where Aircraft X was descending out of 6;000 for 4;000. Aircraft Y entered my airspace without a point-out. The STN controller was busy and had several areas of thunderstorms affecting his airspace. Aircraft Y passed less than 5 miles behind Aircraft X; a heavy with 700 feet of altitude. There was several significant areas of precipitation affecting the entire airspace and every sector was overwhelmed including the supervisors. There was not enough staffing to staff hand-off positions and coordinator positions. Supervisors were having to work Coordinator positions for the MCO departure sectors and arrivals sectors and were not able to keep an eye on other sectors than may need attention.I recommend adequate staffing levels to staff coordinator and hand-off positions so that supervisors are not having to stand behind just 1 sector to coordinate for an extended period of time and they can keep an eye on the entire operation. It is a known issue that F11 experiences significant thunderstorms every afternoon during the summer months and staffing was decreased instead of increased to allow for necessary positions to be staffed.
Orlando TRACON Controller reported an airspace incursion and a loss of separation due to another Controller being overwhelmed with traffic and weather.
