Beginning Monday, January 8, the KNQA WSR-88D radar operated by the
National Weather Service in Memphis, Tennessee will be down for
approximately four days to install an important technological
upgrade. A crew will install a new signal processor, which replaces
obsolete technology, improves processing speed and data quality,
provides added functionality, and supports IT security.

This is the first of four major upgrades, known as service life
extension projects, planned in the next five years to replace and
refurbish major components of the 20+ year old WSR-88Ds and to keep
the radars operational into the 2030s. The $150M investment is being
made by the three organizations that use these radars, the NOAA
National Weather Service, United States Air Force, and Federal
Aviation Administration. The other service life extension projects
include refurbishing the transmitter, pedestal, and equipment shelter.

The work on the WSR-88D has been scheduled to minimize any potential
impacts to office operations and will be delayed if hazardous weather
is forecast.

During the outage, adjacent radars include: NWS Paducah (KPAH),
NWS Little Rock (KLZK), NWS Jackson MS (KDGX), NWS Nashville (KOHX),
and Columbus Air Force Base (KGWX).  The TDWR site at Memphis (TMEM)
will also be available.  For direct access to any of these surrounding
radar sites, go to the following web page:

The KNQA 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.
