![]() This page will be updated to a more robust version including PIREPs by the end of April. The NWS Radar page and NWS Satellite page also are available. The URL should auto-update with the current settings, allowing for an easy bookmark/favorite. Īdditional URL parameters include lt (center latitude), ln (center longitude), zm (zoom level, 0-12), nolabel (removes flight category icon ID labels), hidemenu (hides the menu options on the lower left), wide (thicken US state boundaries), county (include US counties and other political boundaries based on zoom level), hidefir (hide FIR boundary), zseareas (add the ZSE ARTCC areas), and start (UTC start date/time, YYYYMMDDhhmm format, AWC data goes back up to 2 days, GLM data up to 5 hours). ![]() To expand the radar map, keeping the menus/options above and legend below, click ⟺ (include "&invert" in the URL to reverse the background/text colors). To toggle the lower-left menu visible/hidden, click the ≪ or ≫ button. Left-clicking on the "Speed" area will slow the loop and right-clicking will accelerate the loop, ranging from 0.05 to 5 second interval. : National Oceanic and Atmospheric Administrations : National Weather Service. When both the flight category and weather are displayed, the flight category icon will be on the inside and the partially-transparent weather color on the outside.Ĭlicking on the map will start/stop the loop. Latest weather radar images from the National Weather Service. Also, GeoColor images may occasionally miss a frame or two. Current and future radar maps for assessing areas of precipitation, type, and intensity. ![]() On the GeoColor satellite images (GOES-West/East cutoff at -114°) the pale bule areas are nighttime areas of lower clouds. Also details how to interpret the radar images and. The radar, lightning, visible satellite, IR satellite, GeoColor satellite, SIGMETs/CWAs, and flight categories/weather can be toggled on/off. Provides access to meteorological images of the Australian weather watch radar of rainfall and wind. 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.The above loop uses radar and visible/IR satellite data obtained from Aviation Weather Center (AWC), GeoColor satellite data from NOAA NESDIS-STAR, lightning (GLM) data from NOAA nowCOAST, and observations (for flight category and weather) from MesoWest. Hail is a good reflector of energy and will return very high dBZ values. See a real view of Earth from space, providing a detailed view of. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Current and future radar maps for assessing areas of precipitation, type, and intensity. 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). Alternately, you can view the Wunderground radar loop here, which may be more up to date than the National. One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). Weather Underground weather radar loop for KEMX. 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. Additionally, simulated radar is derived from numerical models, and the output may differ from human-derived forecasts. The interactive map makes it easy to navigate. Note: Radar products are designed for optimal performance on modern desktop and mobile browsers, such as Firefox and Chrome. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). See the latest Tucson, AZ RealVue weather satellite map, showing a realistic view of Tucson, AZ from space, as taken from weather satellites. Choose from dozens of live Tucson weather radar and. ![]() "Reflectivity" is the amount of transmitted power returned to the radar receiver. Tucson, AZ Doppler Radar Weather - Find local 85701 Tucson, Arizona radar loop and radar weather images. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan. Composite Doppler Radar loop for Tucson AZ, providing current animated map of storm severity from precipitation levels.
