Narrative:

An A320 aircraft arrived with a 'possible lightning strike' report from the flight crew. The captain was met by me on arrival and I was briefed by him upon completion of his post flight inspection. In his brief we discussed the 'possibility of a lightning strike' on the lower fuselage aft of the cockpit during flight. We discussed that on his walk-around he did not see any damage in the suspected area or on any area below wing. After our brief I went to the flight deck to obtain the logbook; preceded back to the office for the inspection task 05-51-18; (inspection after lightning strike on condition); suited-up in preparation for the heavy rain that was falling and grabbed my flashlight for the approaching nightfall. Please note that on the same day; our ZZZ airport and the surrounding area experienced a major weather event which involved heavy precipitation fall; severe lightning and associated turbulence which lasted in the area for approximately 36-hours.my inspection where I began with the step by step set up of the aircraft for the visual below and above wing inspections. Upon completion of the aircraft set up; I began a detailed inspection that started at the fuselage radome exterior surface and lightning diverters. I went through the task step by step for the inspection until I was complete. I returned the aircraft to its original configuration per the task and completed the inspection with the logbook and maintenance computer entries. The strike hole was discovered three days later; and was corrected with an engineering order and was released for service. I was notified three days later and resulted is this form being submitted. Gaps in days due to days off of lead mechanic and aviation maintenance technician. Lead mechanic was also not able to notify me on the day of discovery. The only amt action that could be mentioned that might have avoided this event was to ground the A320 aircraft until the weather environment was suitable for a safe inspection.
