Mostly sunny in the morning, then partly cloudy with showers and thunderstorms likely in the afternoon. 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.60632 WEATHER WARNINGS (SEVERE T-STORM & TORNADO) 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. This view is similar to a radar application on a phone that provides radar, current weather, alerts and the forecast for a location. The value of the dBZ depends upon the mode the radar is in at the time the image was created. This view combines radar station products into a single layer called a mosaic and storm based alerts. Notice the color on each scale remains the same in both operational modes, only the values change. One of two major storm waves expected to pound the Chicago area Friday arrived in the late. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). Use the live interactive radar below to track whats happening in your area. Check the latest weather conditions, get location-specific. One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). You can also view current severe weather warnings & watches for Milwaukee on the WISN alerts page. 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. fire danger outlooks, Doppler and satellite images, and thousands of maps. Chicago, IL Use Current Location Radar & Maps Home & Garden Forecasts AccuWeather. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. MyForecast is a comprehensive resource for online weather forecasts and reports. Chicago, IL Doppler Weather Radar Map - effective May 25, 2018. 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.
