...DISCUSSION...
A QUIESCENT PATTERN FOR SEVERE POTENTIAL WILL PERSIST INTO THIS
WEEKEND OWING TO THE LACK OF SUFFICIENT BUOYANCY IN THE CONUS. EARLY
NEXT WEEK...GUIDANCE HAS TRENDED TOWARD INCREASED CONSISTENCY WITH A
MODERATELY-AMPLIFIED AND PROGRESSIVE UPPER-LEVEL TROUGH MOVING INTO
THE CNTRL CONUS AROUND D6/MON. LOW-LEVEL MOISTURE RETURN FROM THE
WRN GULF APPEARS MODEST BUT SUFFICIENT FOR TSTM DEVELOPMENT ALONG A
COLD FRONT SWEEPING E/SEWD FROM THE MID-MS VALLEY TO THE SRN PLAINS.
ATTM...IT APPEARS STRONGER FLOW AND FORCING SHOULD BE DIVORCED FROM
THE COMPARATIVELY GREATER POTENTIAL BUOYANCY CLOSER TO THE COAST. AS
SUCH...SOME RELATIVE INCREASE IN SEVERE POTENTIAL IS APPARENT...BUT
STILL WELL BELOW THE AOA 30 PERCENT THRESHOLD FOR HIGHLIGHTING AN
AREA.
