...Weather Radar Upgrade Rescheduled...

The weather radar KDMX Des Moines used by the Des Moines National
Weather Forecast Office will be down for approximately five days
beginning Tuesday, October 24th for technicians to install an
important technological upgrade. The work on the WSR-88D has been
scheduled to minimize any potential impacts to office operations.

During the outage, radar coverage is available from adjacent radar
sites including: KOAX Omaha, KDVN Davenport, KFSD Sioux Falls,
KARX La Crosse, KMPX Minneapolis and KEAX Pleasant Hill.

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 $150 million 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 shelters.
