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. Updated 10:32PM Weather FOX 9 Minnesota weather: Icy conditions overnight into Wednesday After a snowy Tuesday, conditions are turning icy overnight. 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. Minneapolis, MN Doppler Radar Weather - Find local 55199 Minneapolis, Minnesota radar loop and radar weather images. 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. Our interactive map allows you to see the local & national weather. The value of the dBZ depends upon the mode the radar is in at the time the image was created. See the latest Minnesota Doppler radar weather map including areas of rain, snow and ice.
Notice the color on each scale remains the same in both operational modes, only the values change.

So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. 1 Today Hourly 10 Day Radar Season South St. 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.
