AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
330 PM CST THU MAR 2 2000

STRONG TO SEVERE THUNDERSTORMS DEVELOPED FROM BOWIE TO EASTLAND AT
2130Z.  UNUSUALLY HIGH DIRECTIONAL AND SPEED SHEAR ENVIRONMENT IS IN
PLACE WITH SURFACE LOW PRESSURE CENTERED NEAR ALTUS OK...DRYLINE
EXTENDING SOUTH THROUGH BRECKENRIDGE TO NEAR SAN ANGELO...AND A WARM
FRONT STRETCHING SOUTHEAST THROUGH DALLAS TO LONGVIEW.  JET MAX WILL
WORK AROUND THE UPPER LOW SYSTEM THIS EVENING...SO STRONG LIFT
SHOULD GRADUALLY OVERCOME THE CAPPING INVERSION LOCATED FROM D/FW
EASTWARD.  IN ADDITION...CLOUDS WERE BREAKING A BIT AND SHOULD
PROVIDE A BIT OF SURFACE HEATING BEFORE SUNDOWN.  EXPECT SEVERE
THREAT TO CONTINUE...ESPECIALLY EAST OF THE DRYLINE AND SLIGHTLY
NORTH OF THE WARM FRONT WHERE TORNADO THREAT REMAINS HIGH.

AS THE SYSTEM EXITS EAST ON FRIDAY...WRAPAROUND MOISTURE WILL KEEP
CONSIDERABLE CLOUD COVER AND STRONG COLD ADVECTION SHOULD COOL OFF
AREA.  TIGHT PRESSURE GRADIENT SUGGESTS POSSIBLE WIND ADVISORY ON
FRIDAY...BUT WILL DEFER UNTIL WE GET A SOLID HANDLE ON THE DEPARTURE
OF THE CURRENT SYSTEM.

ANOTHER UPPER LOW PRESSURE SYSTEM STARTS TO INTENSIFY OVER THE SW
U.S. DURING THE EXTENDED PERIOD.  SHORTWAVE ENERGY EJECTS AHEAD OF
THE SYSTEM AND COULD BRING A BRIEF SHOT OF THUNDERSTORMS ON SUNDAY
NIGHT AND MONDAY.  THE MAIN SYSTEM SHOULD COME THROUGH
WEDNESDAY/THURSDAY...BRINGING A BETTER OPPORTUNITY FOR THUNDERSTORMS.
