Beginning Monday, January 14th, the KLZK WSR-88D radar operated by the
NOAA National Weather Service in Little Rock, AR will be down for
approximately 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 20-year-old
radar operating smoothly for another 20 years.
This transmitter update is the second major project 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. NOAA National Weather
Service, the United States Air Force, and the Federal Aviation
Administration are investing $150 million in the seven year program. The
first project was the installation of the new signal processor. The two
remaining projects are the refurbishment of the pedestal and equipment
shelters. The Service Life Extension Program will complete in 2022.
During the downtime, adjacent radars include: KSRX in Fort Smith, AR;
KNQA, in Memphis, TN; KSGF, in Springfield, MO; and KSHV in Shreveport,
LA. For direct access to any of these surrounding radar sites, go to the

The KLZK 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.
