KJAN/KDGX   RADARS
STORM OF THE MONTH




You have arrived at the NWFO Jackson Mississippi Storm of the Month webpage. Here you can view RADAR images of intense storms that occurred within the KJAN(Jackson MS)or KDGX(Brandon MS) WSR-88D Coverage Umbrellas of approximately 124nm and that were selected by the staff as being most impressive for that particular month. The KJAN radar served the area from 4/1993 to 2/2003 and the KDGX 88D radar began coverage for the area on 2/19/2003.  The new radar location facilitates improved radar detection ability for much of the eastern third of Mississippi...especially in regard to rainfall amounts. 


The icons in the table below give you an indication of the type of storm for that month. Some of the image files are quite large and may take a few moments to load. You may click on any icon in the table to see the contest winner for that month which includes brief highlights of the storm. Each month's winner may not necessarily be the storm that inflicted the most damage. At the end of the calendar year, we select a winner from among the twelve monthly entries.



It is our hope that professionals, amateurs, and retirees will all benefit from viewing these images since no one person will likely ever experience in real-time the variety that all these storms represent. The methods we utilize to view radar imagery will certainly change over the years as computer technology advances. The advent of Doppler technology at NWS field offices in the early 1990s opened a new window of storm structure information. We hope you are as impressed with nature's display of power represented in these storms as we have been and still are. For example, compare the quality of the images below: the first set is from our original radar display system called the Principal User Processor(PUP) and the second from a newer and faster system called Warning Decision Support Software(WDSS). Advancing computer analysis techniques are revealing more and more useful data about individual storms including what they might produce.

Here are the two views of our 1995 Yearly WINNER that occurred in Claiborne County. The first images came from the original radar PUP screen display in operational use at the time.

These second images of the same storm were later reprocessed by the newer

WSR-88D Algorithm Testing And Display System(WATADS)

which has developed into operational WDSS.
