Weather Talk: Upgrade of Doppler radar gets under way this week

On Tuesday or shortly thereafter, the National Weather Service Doppler radar in Mayville, N.D., will be turned off for a week or so. During the outage, forecasters will rely on other Dopplers in the region as well as increased attention on storms from area storm spotters in order to keep people alerted to any severe weather.

Technicians will be adding new technology to the Doppler transmitter so that it will be equipped with the most modern radar technology available. Dual-Polarized Doppler will greatly enhance the Doppler’s ability to estimate rain amounts, hail size, and to determine the boundaries between rain and snow.

Dual-Pol Doppler also offers advantages during some tornado situations, such as the ability to spot flying debris in certain conditions, making it easier for forecasters to tell if a tornado is on the ground.

This upgrade is part of a multimillion-dollar upgrade to the National Weather Service Doppler radar system across the country.
