![]() Discover the weather conditions in Meriden & see if there is a chance of rain, snow, or sunshine. 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. Stay informed on local weather updates for Meriden, CT. Hail is a good reflector of energy and will return very high dBZ values. Rainfall Storm Total Doppler Radar for Meriden CT, providing current static map of storm severity from precipitation levels. 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. AccuWeather meteorologists say the threat of tornadoes, including some that could form after dark, will return to the South as well as areas of the Midwest that have largely avoided damaging. 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. MERIDEN, CT Weather Map Discussion, 5 am & 4pm Coastal Waters Forecast, 4 am, 10 am, 4 pm & 10 pm Offshore Marine Forecasts: South of New England. 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. Winsted, CT Weather and Radar Map - The Weather Channel Weather. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). Connecticut Traffic, Live Traffic Reports & Traffic Map CTroads Alerts MERIDEN. ![]() "Reflectivity" is the amount of transmitted power returned to the radar receiver. AccuWeather forecasters break down what to expect with the approaching wintry weather. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan. Places up and down the Eastern Seaboard enjoyed a spring preview Sunday and Monday.
