Officials say a radar upgrade at the National Weather Service office in Cleveland will allow forecasters to get a more accurate look at severe weather.The upgrade to dual polarization radar will enable forecasters to see what's in clouds in two dimensions rather than one. That will allow them to accurately tell if a storm is producing heavy rain, hail, sleet, snow or a mixture, and the rate at which it is falling. The service is spending 50 million dollars to install the new radar at 160 stations nationwide.
