Ozone, particulate, and sulfur dioxide levels are sampled through the Lung Association and Missouri Department of Natural Resources, Air Quality Division, and the U.S. Missouri Weather Radar AccuWeather Radar Satellite Current Conditions Forecast. And to help you breathe easier, we monitor allergens through the St. Missouri Weather Doppler RadarNational Weather Service Springfield. With a network of over 35 cameras throughout the viewing area, we can even show when and where air masses are changing and precipitation types are changing.įor astronomers, we track the moon phase and provide star charts for significant celestial events. With fast-changing air masses, computer software samples temperatures from hundreds of weather stations around the viewing area and the country to show temperature trends so that you can prepare for flash freezes, heat waves, cold fronts, and warm fronts to help dress for the changing air masses. The radars precise location is latitude 38.698611, longitude -90.682778, at an elevation of 722 feet. Tornadoes, flash flooding, severe thunderstorms, and winter weather driving conditions are the favorite chase items. KLSX is the ICAO code for the nexrad doppler radar located in ST LOUIS, MO. It is a mobile weather broadcast weather center. It has a built-in weather station, three cameras, editing and recording equipment, road temperature sensing equipment, and live broadcast capabilities. Not only do we study weather in the studio, but we also chase severe weather in the field with the Woods Basement System Stormrunner. There are two weather centers to track, forecast, and help you understand how weather works. It also tracks rain, freezing rain, sleet, snow pellets, and snow.įrom winter storms with snow, sleet, and freezing rain to severe thunderstorms with lightning, thunder, wind, and tornadoes we have the best weather equipment. It can even tell what type of precipitation is falling, how strong the winds are, and where the winds are rotating. Power Doppler, located in Weldon Spring, Missouri scans the sky for precipitation. In addition, our meteorologists have more experience than the competition with over 100 years in the field. 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.Every season, every hour, every day, FOX 2 and KPLR 11 covers all types of weather with more meteorologists than any other station. com 26 Today Hourly 10 Day Radar Storms Hazelwood, MO Radar. Hail is a good reflector of energy and will return very high dBZ values. Louis weather forecast, flood warnings and updates about weather in St. 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. Current and future radar maps for assessing areas of precipitation, type, and intensity. 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. Louis Weather Radar Now Rain Snow Ice Mix United States Weather Radar Michigan Weather Radar More. Louis, Missouri daily and weekly weather forecasts from KMOV First Alert Weather. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Today Hourly Daily Radar MinuteCast Monthly Air Quality Health & Activities St. 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). Video Forecast Tracking isolated storms with extreme heat this afternoon How to set up weather app alerts How to add locations How to get notifications How. 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). "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.
