...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
STRONG LARGE SCALE UPPER RIDGE ALONG THE WCOAST WILL EDGE EWD THE
NEXT COUPLE OF DAYS.  THIS WILL CAUSE THE VIGOROUS MID-LEVEL
SHORTWAVE TROUGH...NOW MOVING ONTO THE NRN HIGH PLAINS...TO AMPLIFY
AND DIG SEWD.  THE IMPULSE SHOULD REACH THE CNTRL PLAINS/CORN BELT
AND BEGIN TO CLOSE-OFF INTO A CYCLONE BY LATE TONIGHT. AT THE
SURFACE...RAPID CYCLOGENESIS WILL OCCUR THIS AFTN OVER THE CNTRL
PLAINS WITH THE LOW DEVELOPING RAPIDLY SEWD TOWARD SRN IA/NRN MO BY
12Z SATURDAY.  

...ARKLATEX REGION...
GPS PWAT AND 12Z SOUNDINGS SHOW A NARROW TONGUE OF MOISTURE
ADVECTING NWD THROUGH ERN TX AND THE ARKLATEX REGION LATE THIS
MORNING.  THE BOUNDARY LAYER SHOULD CONTINUE TO MOISTEN THROUGH THE
AFTN AS MODEST LOW-LEVEL FLOW IS MAINTAINED AHEAD THE AMPLIFYING
UPPER TROUGH.  

TSTM POTENTIAL WILL INCREASE OVERNIGHT ACROSS THE ARKLATEX REGION AS
THE UPPER IMPULSE APPROACHES THE REGION.  SHORT TERM MODELS/09Z SREF
AGREE THAT THE COLUMN WILL MOISTEN AND WEAKLY DESTABILIZE ALOFT AS
THE ENHANCED UVV SPREADS SEWD ATOP THE MOIST AXIS. HIGHEST TSTM
PROBABILITIES WILL OCCUR AFT 09Z AND PRIMARILY BE CONFINED TO
CNTRL/SRN AR.  BUOYANCY SHOULD REMAIN SUFFICIENTLY WEAK TO PRECLUDE
ORGANIZED SEVERE TSTMS...HOWEVER.

...CNTRL PLAINS...
TSTMS MAY ACCOMPANY STRONG DCVA SPREADING SEWD THROUGH SRN SD/NRN
NEB THIS AFTN. ACTIVITY SHOULD REMAIN ISOLD ENOUGH TO PRECLUDE A
GENERAL TSTM OUTLOOK ATTM.
