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. in which weather and interviews will be spotted in a 'Terry toons' hour, with more cartoons in a 9:30-10 a.m. Future radar to see where severe weather is headed. 250 meter radar, the highest resolution available. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. The KPLC Mobile Weather App includes: Access to station content specifically for our mobile users. 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. Local News Live/WAFF Original Content 11 a.m. The higher the dBZ, the stronger the rainrate. WELCOME TO THE WAFF 48 NOW LIVESTREAM CLICK HERE FOR 48 NOW ORIGINAL CONTENT ON DEMAND CLICK HERE FOR THE LATEST NEWS VIDEOS FROM WAFF 48 WHAT TO EXPECT ON WEEKDAYS: 4:30 a.m. 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. Lake Charles, LA current today tonight 73 F° C° Cloudy Pressure 29. 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. Current weather updated multiple times per hour. The dBZ values increase as the strength of the signal returned to the radar increases. The KPLC Mobile Weather App includes: Access to station content specifically for our mobile users. 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.
