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. Current and future radar maps for assessing areas of precipitation, type, and intensity. 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. Wind direction is W at 6 mph with visibility of 10.00 mi. The higher the dBZ, the stronger the rainrate. Pomona Park Doppler Radar Current Conditions: Clear, the temperature is 54F, humidity 54. NA 64F 18C More Information: Local Forecast Office More Local Wx 3 Day History Mobile Weather Hourly Weather Forecast Extended Forecast for Pomona CA. 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. Wind direction is NW at 10 mph with visibility of 5.00 mi. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). Pomona Lake Doppler Radar Loop Current Conditions: Light Snow, the temperature is 36☏, humidity 93. One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). 21 hours ago &0183 &32 Coolest air since May forecast for next week WTHR Weather Blog 9/9/23. 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. Wind direction is SSW at 5 mph with visibility of 10.00 mi. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Pomona Doppler Radar Current Conditions: Overcast, the temperature is 39F, humidity 76. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). US airline pilots fight their unions to increase.

"Reflectivity" is the amount of transmitted power returned to the radar receiver. 10 Day Forecast Weather Radar for Zip Code 65789 Pomona, MO. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
