Overlay rain, snow, cloud, wind and temperature, city locations and. 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. Animated Wisconsin weather map showing 12 day forecast and current weather conditions. Hail is a good reflector of energy and will return very high dBZ values. RECENT PROGRESS IN RADAR METEOROLOGY Contents 1 3 22 33 46 58 72 Introduction Recent Advances in Doppler Radar Probing of the Clear Atmosphere - K.S. 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. Notice the color on each scale remains the same in both operational modes, only the values change. MyForecast provides Madison, WI current conditions, detailed, hourly, 15 day extended forecasts, ski reports, marine forecasts and surf alerts, airport delay forecasts, fire danger outlooks, Doppler and satellite images, and thousands of maps. Mountain WI radar weather maps and graphics providing current Base Reflectivity weather views of storm severity from precipitation levels with the option. 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. 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).

Other mainstem rivers in southeast Wisconsin also went.

The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan. WSR - 88D Doppler radar estimated that 2 to 3 inches fell in about 1.5 hours.
