Given our Doppler Radar is a very large piece of constantly rotating equipment, inevitably parts will need replacing. Today it was the rotary joint that allows the dish to turn. Radar is an essential tool for our forecasters, so we thank our technicians for their great work! pic.twitter.com/pEzBxtaErF— NWS Chicago (@NWSChicago) February 6, 2018
