Hail is a good reflector of energy and will return very high dBZ values.
These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Depending on the type of weather occurring and the area of the U.S., forecasters use a set of rainrates which are associated to the dBZ values. The higher the dBZ, the stronger the rainrate. This feature allows you to see meteorological conditions for various locations at once. Typically, light rain is occurring when the dBZ value reaches 20. WeatherRadar More than just your standard weather map See the latest enhanced radar map, which includes areas of cloud cover, sunshine, rainfall, snowfall, hail, thunderstorms, and lightning strikes. The scale of dBZ values is also related to the intensity of rainfall. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion. Notice the color on each scale remains the same in both operational modes, only the values change.
Wednesday 21 June is said to be sunny with some clouds with a thunderstorm warning between. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). 2 days ago &0183 &32 You can find the rundown of the weather forecast for Glastonbury as noted by Accuweather below. One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). Each reflectivity image you see includes one of two color scales. The dBZ values increase as the strength of the signal returned to the radar increases. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). "Reflectivity" is the amount of transmitted power returned to the radar receiver. Frequently echoes can be seen from Snowdonia, the Pennines, the Lake District and other areas of high ground even when no rainfall is actually present.The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.

Sometimes the radar will not 'see' rain at long ranges or report rain at high altitudes that does not reach the ground. At longer ranges, typically over 100km, the accuracy falls off due to the curvature of the Earth. Using radar we can get a picture of the extent and intensity - the greater the intensity of rainfall, the stronger the signal returned. By rotating the antenna and sending out a stream of pulses, the radar can build up a picture of objects. By measuring the time taken for the pulse to reach the object and travel back to the radar, the distance can be calculated.
