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. 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. Also, GeoColor images may occasionally miss a frame or two. On the GeoColor satellite images (GOES-West/East cutoff at -114°) the pale bule areas are nighttime areas of lower clouds. The radar, lightning, visible satellite, IR satellite, GeoColor satellite, SIGMETs/CWAs, and flight categories/weather can be toggled on/off. KEMX Tucson, Arizona Based Nexrad Doppler Radar Station with Enhanced Nexrad Doppler Radar from the National Weather Service for the General Tucson, AZ. Bright reflectivity returns that are stationary and appear during both calm and inclement weather are usually land-based obstructions such as mountains, trees, or especially wind farms (nothing gets electromagnetic signals confused like spinning metal blades!).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.This is helpful for picking out snow/mix/rain transition zones In all snow situations, dBZ values of 40 indicate 3-4”/hr snowfall rates and whiteout conditions. Anything larger than this is usually due to “bright banding” where the radar is seeing the part of the atmosphere where snowflakes are clumping together and melting into raindrops. In cold climates during the winter months, actual dBZ values rarely exceed 40.This is your standard radar data that shows precip or other solid/liquid particles in the atmosphere. The first type of data currently available is reflectivity. We currently have two types of radar data available with plans to add more soon. Use radar data with caution especially if your area of interest is far from the nearest radar location! A lot can happen between 0 and 5,000 feet and therefore the depiction of precipitation given by radar may differ some from what’s actually happening on the ground. Because of this phenomenon, the radar beam will only see precipitation falling through the mid levels of the atmosphere. To see this in action, imagine a circle (earth) with a straight line emanating from some point on the circle if you continue this line out into space, it will gradually get farther and farther from the circle. Because the earth is round and the radar beam is flat, the farther away from the radar tower the beam (energy) travels, the farther removed from the ground becomes. There is a notable constraint to radar data though. This is the highest resolution radar data available which enables you to see features such as sea breeze or outflow boundaries that standard resolution radar entirely misses.

This data is gathered from over a hundred radar towers located across the US. For more information please see SCN 20-85.
