DAY 1 CONVECTIVE OUTLOOK  
NWS STORM PREDICTION CENTER NORMAN OK
0648 AM CST TUE DEC 19 2006

VALID 191300Z - 201200Z

...NO SVR TSTM AREAS FORECAST...

LARGE/DEEP UPPER LOW OVER AZ/CA WILL TRACK SLOWLY EASTWARD TODAY
INTO NM.  MEANWHILE...FORCING FOR UPWARD VERTICAL MOTION WILL
OVERSPREAD MUCH OF THE SOUTHERN PLAINS STATES...HELPING TO CREATE A
LARGE PRECIPITATION SHIELD ACROSS THE REGION.  CLOUD COVER AND WEAK
LAPSE RATES WILL SUPPRESS CAPE VALUES TO BELOW 500 J/KG.  THIS MAY
BE ENOUGH FOR ISOLATED THUNDERSTORMS THROUGHOUT THE FOUR CORNERS
REGION INTO PARTS OF TX/OK/KS.  STRONG LINEAR FORCING AND INCREASING
WIND FIELDS ALOFT MAY SUPPORT A RISK MORE ORGANIZED THUNDERSTORM
ACTIVITY OVER TX LATE TONIGHT.  HOWEVER...SEVERE THREAT APPEARS TOO
LOW TO WARRANT PROBABILITIES AT THIS TIME.
