I’ve tried other local channels, just not impressed. Base Reflectivity Doppler Radar loop for Saint Louis MO, providing current animated map of storm severity from precipitation levels. If I can just stay awake at least for the weather with Steve. Thank you so much for your up to date reporting not just while I get ready in the morning but your evening and nightly reports, which I also look forward to. Oh my, when we have hurricanes, I’m all ears. You even let me know about weather disasters in other states. Louis but has offices located all over the US so I feel the need to know what’s going on.

When I’m out of town to visit family in Michigan or Colorado, I’m totally lost on their news programs in just hunting through their programs to get what I need for the days. 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.It’s the only news, traffic and weather I watch. 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. 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). 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. 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). Contact the helpdesk for operational issues. Review the Radar FAQ for help with the transition to the new site. The radar products are also available as OGC compliant services to use in your application. "Reflectivity" is the amount of transmitted power returned to the radar receiver. The NWS Radar site displays the radar on a map along with forecast and alerts. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan. Louis, Missouri daily and weekly weather forecasts from KMOV First Alert Weather.
