.DISCUSSION...

AGAIN LARGE DEGREE OF OVERNIGHT CONVECTION TO S AND ONGOING MORNING
ACTIVITY...WHICH COMPLICATES MAIN ISSUE FOR DAY...WHICH IS SEVERE
WEATHER POTENTIAL.  OTHER THAN OBVIOUS AIRMASS MODIFICATION ISSUES
AND CLOUDS WHICH WL LIMIT SFC BASED DESTABILIZATION TDA OVER MAINLY
E...MAIN PROBLEM IS THAT UPPER LEVEL ENERGY DOES NOT TIME OUT WELL
FOR SEVERE THREAT...AS WAVE MOVES THROUGH LATE MORNING THROUGH EARLY
AFTERNOON WITH RISK OF ELEVATED TSRA.  UPR FORCING ABANDONS LOW LVL
FRONTAL ZONE/DRYLINE ACRS FAR WRN AREAS FOR LTR AFTERNOON...AND
ACTUALLY WL BE IN A WKLY LIFT HOSTILE ENVIRONMENT FOR A WHILE THIS
AFTERNOON.  SOURCE OF MID AND HIGH CLDS FM CONVECTION WL WKN GRIP ON
WRN AREAS LATER MORNING AND MIDDAY...ALLOWING BREAKING/CLEARING OF
CLDS AS WAVE MOVES BY. THIS WL BRING DECENT SFC HEATING INTO
PICTURE. HOWEVER...MOISTURE IS NOT NEARLY AS GOOD IN TRAJECTORY FOR
THIS AREA AS WNDS VEER SOMEWHAT...WITH DEEP WLY FLOW AT MRR...AND
INCREASINGLY WLY LOW LVL ALREADY AT NLG. STG UPR JET PUNCHES INTO SD
DURING LTR AFTN WITH ENTIRE AREA IN EXIT REGION. MOST DIVERGENT AND
LIFTY AREA WOULD BE ACRS NRN CWA...BUT WLY COMP REALLY FLUSHES OUT
THE MOISTURE ALFT. LOW LVL CONVERGENCE AXIS SETS UP ALG JAMES VLY
BY LATER AFTN...AND THIS ALONG WITH WAA REGION AHEAD WOULD BE FOCAL
AREA FOR AFTERNOON DEVELOPMENT AS STEEP MID LVL LAPSE RATES NOTED ON
WRN RAOBS LIES ABOVE THERMAL ZONE.  FOR NOW...WL DROP THINGS BACK TO
ISOLD ALONG CONVERGENCE AXIS FOR AFTN...BUT MAY HAVE TO RAISE KHON
AREAS BACK TO SCT LVL COVERAGE.

NOTE...IF ANYTHING DOES GET GOING ALONG THE DRYLINE...IT WILL
CERTAINLY HAVE A DECENT SEVERITY POTENTIAL WITH DEEP LAYER SHEAR.
EXPECT ISOLD SUPERCELLS TO DEVELOP...WITH LOW WBZ TO KEEP LARGE HAIL
THREAT AND DAMAGING WIND WITH STRENGTH OF SR MID LVL FLOW.

UPDATES OUT EARLIER...ANY MAY HAVE TO MAKE TWEEKS TO LOWER SOME ERN
TEMPERATURES AFTER A LITTLE FURTHER REVIEW MIDDAY...AND EVEN POSSIBLY
RAISE TMPS A BIT ACRS FAR W.
