![]() Since hail can cause the rainfall estimates to be higher than what is actually occurring, steps are taken to prevent these high dBZ values from being converted to rainfall. 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. 5am-9am WBAP Morning News Team 9am 11am The Casey Bartholomew Show 11am-2pm Dan Bongino Show 2pm-5pm WBAP Afternoon Show. 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. Typically, light rain is occurring when the dBZ value reaches 20. 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. Notice the color on each scale remains the same in both operational modes, only the values change. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). DFW weather: Windy day ahead of rain, cold front moving in over weekend DFW Weather: Warm temps ahead of weekend cold front, rain chances DFW Weather: Whats the chance for severe. 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. At the same time, The National Weather Service issued storm warnings in Tarrant, Johnson and. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). Hail stones the size of cricket balls and winds of up to 87 kilometres per hour were recorded in some areas. a strong line of storms coalesced and pushed toward the Metroplex from the west. "Reflectivity" is the amount of transmitted power returned to the radar receiver.
