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. 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. Abbreviated Kxgj-Fm Bay City Weather Forecast 6 Day/Night Kxgj-Fm Bay City Weather Forecast 7 Day Kxgj-Fm Bay City Weather Forecast 14 Day Kxgj-Fm Bay City Weather Forecast Weather Radar. 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. Scattered thunderstorms in the morning, then partly cloudy late. Typically, light rain is occurring when the dBZ value reaches 20. The scale of dBZ values is also related to the intensity of rainfall. Weather forecast for Houston, Texas, live radar, satellite, severe weather alerts, hour by hour and 7 day forecast temperatures and Hurricane tracking from. 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. Read the air pollution in Bay City, Texas with. Winters are mild and short, with highs in the mid-60s F (low-teens Celsius) and lows in the mid-40s F (low-7 Celsius). Summers are hot and humid, with average high temperatures in the mid-90s F (mid-30s Celsius) and lows in the mid-70s F (low-20s Celsius). Get real-time, historical and forecast PM2.5 and weather data. Bay City, Texas has a mild climate year-round. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). Bay City Air Quality Index (AQI) is now Good. 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. is the official website for KENS-TV, Channel 5, your trusted source for breaking news, weather and sports in. The dBZ values increase as the strength of the signal returned to the radar increases. Weather forecast and conditions for San Antonio, Texas and surrounding areas. 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.
