![]() 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. Hourly Weather Forecast for Pomona Park, FL. Wind direction is W at 7 mph with visibility of 10.00 mi. Pomona Hourly Forecast 48 Hour View Views Today Sunny Sunny, with a high near. Hail is a good reflector of energy and will return very high dBZ values. Pomona Junior College Doppler Radar Current Conditions: Clear, the temperature is 54☏, humidity 58. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Wind direction is WNW at 15 mph with visibility of 6.00 mi. 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. Pomona Baptist Church Doppler Radar Current Conditions: Light Snow, the temperature is 34☏, humidity 76. Radar Current Weather Rivers & Lakes Satellite Forecast Maps Hour by Hour Forecast Winter Weather Graphical. 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. Click on the Layers menu in the bottom right of the radar to select radar options like Current Conditions, Storm. Wind direction is W at 9 mph with visibility of 10.00 mi. Track rain, storms and weather wherever you are with our Interactive Radar. ![]() The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). Pomona Superior Court Doppler Radar Current Conditions: Clear, the temperature is 90☏, humidity 10. One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). The radar products are also available as OGC compliant services to use in your application. Each reflectivity image you see includes one of two color scales. The NWS Radar site displays the radar on a map along with forecast and alerts. 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.
