20050331: WWDISP no longer plots severe wx (thundestorm/tornado) watches

Hi,

A Unidata user has reported that the v2004 WWDISP command no longer
plots "convective (severe thunderstorm/tornado)" watches, while "Winter
ones, and flood watches plot fine".  He further comments:  "It stopped
working after the watch-by county SLS product was dropped by the WFOs.
I have the new products going in, but they apparently aren't decoding."

Can you verify that this assertion is correct?

If this is correct, then what are the needed changes for the
SEVERE_WX_WATCH_OUTLINE definition in WXCORE.PRD?

I note the  November 8, 2004 admin message sent in NOAAPORT that
relates to this:

 ...

ON TUESDAY...FEBRUARY 22 2005 AT 1200 UTC... DESIGNATED WFOS IN
THE CONTIGUOUS UNITED STATES WILL DISCONTINUE ISSUING STATE AREAL
OUTLINE STATEMENTS /SLS/ TO DEPICT COUNTIES AND INDEPENDENT CITIES
IN INITIAL SEVERE THUNDERSTORM AND TORNADO WATCH AREAS FOR THEIR
STATE OR STATES.

THE INFORMATION CONTAINED IN THE SEV AND SLS PRODUCTS CAN NOW BE
FOUND IN THE WATCH OUTLINE UPDATE MESSAGE /WOU/ ISSUED BY THE SPC.

 ...

Thanks in advance for any insight you can provide!

Cheers,

Tom
