...Weather Radar Upgrade Scheduled at Great Fals...

The weather radar used by the National Weather Service Forecast
Office in Great Falls, MT will be down for approximately four days
beginning March 27 as technicians will install an important upgrade.
The work on the weather radar has been scheduled as to minimize
potential impacts to office opperations, and will be delayed if
hazardous weather is forecast.

During the outage, radar coverage will be available from nearby
radar sites including Billings, Glasgow, Missoula and Pocatello.

A crew will install a new signal processor, which replaces obsolete
technology, improves processing speed and data quality, and provides
additional functionality and security.

This the first of four major upgrades, known as service life
extension projects planned over the next five years to replace and
refurbish major components of the 20-year old radars, and keep them
operational into the 2030s. The $150M investment in the radars is
being made by the three organizations that support these radars,
including NOAA`s National Weather Service, the U.S. Air Force and
the Federal Aviation Administration. The other service life
extension projects include refurbishing the transmitter, pedestal
and equipment shelters.

The tri-agency Radar Operations Center, which supports the radars,
estimates that it will take about 10 months to upgrade the signal
processor on all 159 operational weather radars.
