![]() ![]() Intensifying storms (strong updrafts) would show increasing DVIL values. In fact, a storm with lowering DVIL values could be a collapsing cell about to produce a microburst before weakening. DVIL trends over time are very important and indicate growing or decaying storms. Other cells had lower DVIL values and were weaker at this time. The storm southeast of Elizabethtown in Hardin County also was strong. The storm with the light brown color in Nelson County was severe, and had the highest DVIL values compared to other storms nearby. Limitations exist, but it gives NWS forecasters a quick assessment of storms in an area.Ībove, DVIL is shown for several thunderstorms in north-central Kentucky in April 2011. National Weather Service Louisville, KY 6201 Theiler. ![]() For example, in volume coverage pattern (VCP) 212 (i.e., radars antenna scan strategy), the radar scans 14 elevation angles in about 4 minutes. It helps differentiate the relative strength and depth of storms. With NWS Doppler radar, all elevation angles (tilts) within a particular volume scan can be viewed very quickly using the 'All Tilts' product. The interactive map makes it easy to navigate around. DVIL is useful to identify storms containing hail and a large liquid water content (i.e., deep, tall storms). See the latest Kentucky RealVue weather satellite map, showing a realistic view of Kentucky from space, as taken from weather satellites. DVIL is a vertical integration of reflectivity values within the full depth of a thunderstorm, with values converted to equivalent liquid water. This is an example of the Digital Vertically Integrated Liquid (DVIL) derived product. NWS Doppler radar shows the location, intensity, and movement of precipitation, ranging from light snow flurries to very heavy rain and large hail. Contact the helpdesk for operational issues.

Weather forecast and conditions for Louisville, Kentucky and surrounding areas. The last row contains various dual pol images. The images below show various products and data from the NWS Louisville Doppler radar. The radar products are also available as OGC compliant services to use in your application. Louisville KY radar weather maps and graphics providing current Base Reflectivity weather views of storm severity from precipitation levels with the option. NWS Doppler Radar (WSR-88D) Example Data Fields. This is very important, for example, during thunderstorm events where forecasters need to. Although limitations exist, the overall estimates usually are quite good and alert forecasters to locations where heavy precipitation is or has occurred. NWS Doppler Radar (WSR-88D) Example Products The NWS Radar site displays the radar on a map along with forecast and alerts. NWS Doppler radar produces 1-hour, 3-hour, user-defined, and storm-total precipitation estimates. ![]()
