Aircraft X and Aircraft Y were descending into DAY. The weather in the area was heavy and extreme precipitation was displayed on radar. Aircraft are both requesting detailed information about weather and information on DAY. The DAY weather and RVR were rapidly changing due to thunderstorms in the area. Numerous times over the course of the descent into Dayton; the Dayton METAR; wind; altimeter; RVR; and RBDT (Windshear Ribbon Display) feeds were lost on the NIDS (NAS Information Display System) and relevant information was not able to be passed onto the pilots in a timely manner. This issue has been reported and noted for months and still is creating safety issues for us in the most extreme weather. The NIDS needs to be fixed. Attached is a picture from another instance of the NIDS with big yellow Xs over the relevant information and just blank information for the RVR.
CMH TRACON Controller reported their NIDS (NAS Information Display System) routinely fails to depict current adverse weather conditions.
