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.38351 WEATHER WARNINGS (SEVERE T-STORM & TORNADO) All the Lexington, TN, weather info you need for today and the next seven days. 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. Zoom in to your street or out to your region. Also get information on current severe weather watches and warnings in your area. Click on the Layers menu in the bottom right of the radar to select radar options like Current Conditions, Storm Tracks and Feels Like Temps. The higher the dBZ, the stronger the rainrate. Track rain, storms and weather wherever you are with our Interactive Radar. 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). 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. Wind direction is N at 0 mph0 km/hwith visibility of 10 mile(s) mi16 km. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
