DAY 1 CONVECTIVE OUTLOOK  
NWS STORM PREDICTION CENTER NORMAN OK
0754 PM CDT SUN AUG 27 2006

VALID 280100Z - 281200Z

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS SERN CO/SWRN KS/NERN
NM/THE TX AND OH PANHANDLES...

...CENTRAL AND SRN HIGH PLAINS...
UPPER TROUGH CONTINUES MOVING SEWD INTO THE PLAINS...WITH
LARGE-SCALE ASCENT ACROSS THE CENTRAL AND SRN HIGH PLAINS SUPPORTING
STORMS FROM NWRN KS SWD ACROSS THE SRN HIGH PLAINS.  

STRONGEST SHEAR IS INDICATED FROM KS/CO SWD INTO THE TX PNHDL/NERN
NM...WHERE PRIMARY SEVERE THREAT EXISTS THIS EVENING.  WITH 1000 TO
1500 J/KG MEAN-LAYER CAPE AND KINEMATIC ENVIRONMENT CHARACTERIZED BY
WEAK LOW-LEVEL FLOW BUT DEEP-LAYER SHEAR SUFFICIENT FOR
ORGANIZED/ROTATING STORMS...EXPECT HAIL AND LOCALLY STRONG/GUSTY
WINDS TO BE THE MAIN SEVERE THREATS WITH STRONGEST CELLS THROUGH MID
TO LATE EVENING.

MEANWHILE...INCREASING INSTABILITY SWD INTO THE TRANSPECOS REGION
WILL SUPPORT A MORE ISOLATED SEVERE THREAT ACROSS THIS REGION --
WITH DEVELOPING SELY LOW-LEVEL JET SUPPORTING WIDESPREAD CONVECTION
THROUGH THE REMAINDER OF THE PERIOD.

...OH VALLEY WWD INTO THE OZARKS/ARKLATEX...
LIMITED SHEAR BUT SUFFICIENT INSTABILITY EXISTS ACROSS THE OH VALLEY
REGION AND SWWD INTO THE OZARKS/ARKLATEX...WHERE WIDESPREAD
THUNDERSTORMS ARE ONGOING.  THOUGH OVERALL SEVERE THREAT SHOULD
DIMINISH SLOWLY WITH TIME...LOCALLY STRONG/GUSTY WINDS OR
MARGINALLY-SEVERE HAIL WILL BE POSSIBLE WITH STRONGEST STORMS --
MAINLY PRIOR TO MIDNIGHT.
