Beginning Tuesday, December 3rd, the KABR WSR-88D radar operated by the NOAA National Weather Service in Aberdeen, SD will be down for three to five days for the refurbishment of the transmitter. Although the form, fit, and function of the transmitter will remain the same, old breakers and cables original to the radar will be replaced with modern fuses and new cables.  This will help keep the radar, originally installed in 1994, operating smoothly for another 20 years. The radar is expected to be back in service by Saturday, December 7th.


This is the Transmitter update portion of the NEXRAD Service Life Extension Program, a series of upgrades and replacements that will keep our nation’s radars viable into the 2030’s. The KABR WSR-88D is part of a network of 159 operational radars. The Radar Operations Center in Norman, Oklahoma, provides lifecycle management and support for all WSR-88Ds. NOAA National Weather Service, the United States Air Force, and the Federal Aviation Administration are investing $150 million in the seven-year program.  The Service Life Extension Program will be completed on all radars nationwide in 2023.


During the downtime, data from adjacent NWS radars will be available, including: Grand Forks, ND, Bismarck, ND, Minneapolis, MN, Sioux Falls, SD, and Rapid City, SD. Data from any of these surrounding radar sites can be selected via the website:


During the outage, our office will still perform our standard level of operations and continue to issue necessary hazardous weather warnings and advisories. Meteorologists will be able to utilize neighboring radars; multi-radar multi-sensor (MRMS) derived products, GOES high-resolution satellite data, as well as weather spotter reports.
