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.
United States Radar: NOAA National Weather Radar Maps Wash: E. GOES-EAST & WEST IMAGE VIEWER: NOAA National Weather Radar Mosaic Sectors. Color Satellite Interactive Wx Map US Precipitation US Temperatures US Climate Data. Hail is a good reflector of energy and will return very high dBZ values. Northeast Wx Conditions Northwest Wx Conditions The Plains Wx Conditions. 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. Doppler Radar For The NortheastNortheast Weather Doppler Radar and Satellite Map Our Cape Weather Doppler radar and satellite will display rain, snow, ice.
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. Morning sunshine will give way to a fair amount of clouds this afternoon due to the increasing cold air aloft. See the latest New York 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. WCCO meteorologist Mike Augustyniak is tracking the isolated severe storms possible over the next few hours, with hail the main concern. 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. NOAA’s new interactive radar viewer webpage with expanded radar data will allow you to observe the type and movement of precipitation falling from the sky. AccuWeather forecasters break down which areas are most likely to face heavy snow and a dangerous ice. The dBZ values increase as the strength of the signal returned to the radar increases. Meteorologists rely on weather radar to see developing storms, and now you can, too. Right on the heels of a record-setting blizzard, another winter storm is on the weather maps.

Also details how to interpret the radar images and. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Provides access to meteorological images of the Australian weather watch radar of rainfall and wind. 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. Additionally, simulated radar is derived from numerical models, and the output may differ from human-derived forecasts. Please consult your device documentation for instructions.The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.

On mobile devices, you can save the bookmark as an easy-access icon similar to other apps.

The URL will automatically update as you select the view and settings. Home > Graphical Forecasts > Northeast This graphical forecast page is planned to be replaced by the map viewer now experimentally available at .gov/. This view is similar to a radar application on a phone that provides radar, current weather, alerts and the forecast for a location. This view combines radar station products into a single layer called a mosaic and storm based alerts. This view provides specific radar products for a selected radar station and storm based alerts. The winter storm continued to hurl rain, snow and ice across New England Friday, and AccuWeather forecasters say some more wintry conditions will develop this weekend in the Northeast. This site is organized into views that provide relevant radar products and weather information for a common task or goal.
