.PREV DISCUSSION... /ISSUED 221 PM CDT SAT JUN 13 2009/

SHORT TERM...
STILL FOCUSED ON SEVERE STORM CHANCES THIS AFTERNOON AND EVENING.
WTM SOUNDING /PERSONAL COMMUNICATION/ AND LATEST SPC MESOANALYSIS
PAGE SHOW CIN HAS GREATLY WEAKENED AND THIS IS REFLECTED IN CU
BUBBLING UP TO THE EAST OF LUBBOCK. SURFACE FRONT CONTINUES TO PIVOT
AND SHIFT WESTWARD AROUND 10 KTS AND WAS LOCATED ROUGHLY FROM A
KRESS TO FLOYDADA TO LAKE ALAN HENRY LINE. GIVEN THE VERY STRONG
INSTABILITY IN PLACE /ESPECIALLY EAST OF THE BOUNDARY/ AND
CONVECTIVE TEMPERATURES BEING APPROACHED...STILL EXPECT
THUNDERSTORMS TO ERUPT LATER THIS AFTERNOON. ANY STORMS THAT DO
DEVELOP ARE EXPECTED TO QUICKLY BECOME SEVERE WITH VERY LARGE
HAIL...STRONG WINDS AND ISOLATED TORNADOES. THE BEST TORNADO THREAT
WILL LIKELY BE NEAR AND TO THE MOIST SIDE OF THE FRONT WHERE
INSTABILITY AND LOW-LEVEL SHEAR WILL BE MAXIMIZED AND LCLS AND LFCS
MINIMIZED. ACROSS THE WESTERN ZONES...LOW-LEVEL MOISTURE HAS BEGUN
TO MIX OUT...THOUGH DEWPOINTS IN THE 50S WERE STILL PERSISTING
THROUGH THE CENTRAL SOUTH PLAINS...AND WITH TEMPERATURES CLIMBING
THROUGH THE MID/UPPER 90S...COULD ALSO SEE HIGH-BASED STORMS DEVELOP
HERE.

STORMS COULD ORGANIZE INTO A COMPLEX AS THEY MOVE EASTWARD TONIGHT
INTO A STRENGTHENING SOUTHERLY LLJ. STILL...CAN NOT COMPLETELY RULE
OUT AN OVERNIGHT STORM ACROSS THE SOUTH PLAINS AS AN UPPER LEVEL
DISTURBANCE SLIDES BY TO THE NORTHWEST. STORM CHANCES WILL
REINVIGORATE SUNDAY AFTERNOON AS THE DRYLINE TIGHTENS AND ANOTHER
UPPER LEVEL DISTURBANCE APPROACHES FROM THE WEST. PROGGED
INSTABILITY AND SHEAR WILL AGAIN SUPPORT A SEVERE WEATHER THREAT.
LOWS TONIGHT WILL BE MILD...WITH ANOTHER TOASTY DAY EXPECT SUNDAY.

LONG TERM...
STILL APPEARS THAT SUNDAY AND MONDAY ARE POTENTIAL DRYLINE
CONVECTION DAYS WHILE TUESDAY AND BEYOND WILL FEEL THE EFFECTS OF
AN INCREASING UPPER LEVEL RIDGE. HOT TEMPERATURES THROUGHOUT THE
FCST PERIOD WITH HIGHS IN THE 90S TO 100-105 RANGE. SUNDAY NIGHT
CONVECTION APPEARS MORE LIKELY A LITTLE FURTHER EAST THAN CURRENT
FCST AND HAVE ADJUSTED GRIDS TO SHOW THIS. MONDAY POPS LOOK FINE
AND HAVE LEFT UNCHANGED AND HAVE DROPPED INHERITED SLIGHT CHC POPS
DOWN INTO UNMENTIONABLE RANGE.
