...DISCUSSION...
AN ACTIVE/MULTI-DAY SEVERE RISK WILL BE A DISTINCT POSSIBILITY FOR
AT LEAST PARTS OF THE SOUTH-CENTRAL CONUS ESPECIALLY AROUND DAYS 5-6
TUESDAY/WEDNESDAY...AND PERHAPS INTO DAY 7/THURSDAY. WHILE AT LEAST
CATEGORICAL SLIGHT RISKS SEEM POSSIBLE ON ONE OR MORE
DAYS...CONSIDERABLE GUIDANCE VARIABILITY REGARDING THE EVOLUTION OF
THE SOUTHWEST STATES UPPER TROUGH PRECLUDES ANY SPECIFIC DELINEATION
OF 30 PERCENT EQUIVALENT SEVERE RISK AREAS. IN GENERAL...THE 00Z
ECMWF FEATURES A MUCH SLOWER SOLUTION AS COMPARED TO THE FASTER/MORE
POSITIVE-TILT 00Z GFS/UKMET GUIDANCE.

THAT SAID...CURRENT SPECULATIONS ARE THAT SOME SEVERE TSTMS MAY BE
POSSIBLE ACROSS THE SOUTHERN HIGH PLAINS SUCH AS WEST/NORTHWEST TX
INTO WESTERN OK ON DAY 5/TUESDAY...WITH STRONGER TSTMS POTENTIALLY
ALSO POSSIBLE ACROSS SOUTHERN PORTIONS OF AZ/NM. A MORE WIDESPREAD
SEVERE RISK COULD OCCUR ACROSS THE SOUTHERN PLAINS INTO DAY
6/WEDNESDAY...WITH ALL SEVERE FACETS POTENTIALLY POSSIBLE ESPECIALLY
ACROSS OK/TX AND PERHAPS PORTIONS OF KS/ARKLATEX.
