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. The Mega Millions jackpot is still up for grabs, but a winning 4 million ticket was sold in Central Texas. Hail is a good reflector of energy and will return very high dBZ values. ![]() is the official website for KVUE-TV, Channel 24, your trusted source for breaking news, weather and sports in. Early tests with the Doppler radar have provided 30-minute advance warnings. Weather forecast and conditions for Austin, Texas and surrounding areas. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Two technological breakthroughs should help weather experts spot conditions. See the latest Texas Doppler radar weather map including areas of rain, snow and ice. Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. 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). Get the latest weather news and forecasts from CNNs meteorologists, watch extreme weather videos, learn about climate change and follow major hurricanes. 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. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan. ![]()
