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. 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. 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. Long-term weather report - including weather conditions, temperature, pressure, humidity, precipitation, dewpoint, wind, visibility, and UV index data. Notice the color on each scale remains the same in both operational modes, only the values change. Norco, Louisiana - Detailed weekend and 10-day weather forecast. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). On Saturday, the highest temperature will be a couple of degrees higher than March 's average maximum temperature. As the largest natural gas distribution company in Illinois, Nicor Gas ensures that natural gas an American, abundant, affordable and clean energy source. The maximum temperature will be a moderately hot 75.2F (24C), while the minimum temperature will be a mild 57.2F (14C). One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). On Saturday, in Norco, bright and sunny weather is anticipated.

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. Temperature In Norco, the average high-temperature in May slightly increases from a moderately hot 77.2☏ (25.1☌) in April to a still warm 83.5☏ (28.6☌). The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
