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. At Gray, our journalists report, write, edit and produce the news content that informs the communities we serve. 26 Today Hourly 10 Day Radar Video New Haven, CT Radar Map Rain Frz Rain. The following is a technical discussion of Connecticuts forecast written by Channel 3s meteorologists. Hail is a good reflector of energy and will return very high dBZ values. WFSB Early Warning Weather Rocky Hill, CT. Wtnh Weather Forecast CtNew Haven, CT Weather and Radar Map - The Weather Channel. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. This view is similar to a radar application on a phone that provides radar, current weather, alerts and the forecast for a location. 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. This view combines radar station products into a single layer called a mosaic and storm based alerts. ![]() 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. 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). Temperatures will be in the 90s starting Wednesday and continuing through Friday/Saturday. Each reflectivity image you see includes one of two color scales. ALERT: Hot stretch starting Wednesday, another storm threat Thursday. The dBZ values increase as the strength of the signal returned to the radar increases. Connecticut Weather Radar More Maps Radar Current and future radar maps for assessing areas of precipitation, type, and intensity Currently Viewing RealVue Satellite See a real view of. 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. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
