Our interactive map allows you to see the local & national weather. 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. See the latest Alabama Doppler radar weather map including areas of rain, snow and ice. Hail is a good reflector of energy and will return very high dBZ values. High temperatures will be in the upper 80s to the lower 90s. exports large quantities of live poultry to Canada. Partly cloudy by the afternoon with isolated to scattered afternoon showers and thunderstorms. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. and computers, and weather radars in 85 countries Fagan claims that Republic accounts for 86. 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. Hi - Lo - Live Radar Failed to load Something went wrong loading the data. 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). message about ' hazardous weather ' in northwest Alabama from the Memphis. One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). However, most in the audience had already heard the tapes played ' live. Each reflectivity image you see includes one of two color scales. Alabama 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 Earth. The dBZ values increase as the strength of the signal returned to the radar increases. The best way to keep up with the hit-or-miss thunderstorm action this time of year is with the WVTM 13 app: see our live radar and get updates when rain and storms are getting close to your location. 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.
