MESOSCALE FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
1140 PM CDT FRI JUL 11 2003

.DISCUSSION...
SURFACE OBSERVATIONS/SATELLITE/WIND PROFILERS CONTINUE TO INDICATE
ADDITIONAL THUNDERSTORMS DEVELOPING ALONG AN 85H THETA-E RIDGE AXIS
ACROSS SOUTHERN MISSOURI. WIND PROFILERS OVER NORTHERN OKLAHOMA AND
SOUTHEAST KANSAS ARE ALSO SHOWING AN SIGNIFICANT INCREASE IN THE LOW
LEVEL JET FROM THE SOUTHWEST...WHICH IS IMPENDING UPON SOUTHERN
MISSOURI. 25H JET MAX OF 70K WAS ALSO MOVING INTO THE AREA WHICH IS
LIKELY SUPPORTING ADDITIONAL UPWARD VERTICAL MOTION. TRAINING OF
CELLS IN PHELPS AND DENT COUNTIES HAS ALREADY PROMPTED A FLASH FLOOD
WARNING IN THESE AREAS...AND ADDITIONAL TRAINING OF STORMS WILL
LIKELY AFFECT A PORTION OF SOUTHERN MISSOURI OVERNIGHT.

LATEST RUC/LAPS INFORMATION ALSO SHOW MOISTURE ADVECTION OVER
SOUTHERN MISSOURI THROUGH AT LEAST 12Z...WITH A SLOW PROGRESSION TO
THE SOUTH OVERNIGHT. DEEP MOISTURE WITH PRECIPITABLE WATER VALUES IN
EXCESS OF 1.75 INCHES WILL CONTINUE THE THREAT OF FLOODING
OVERNIGHT...ESPECIALLY IN AREAS THAT RECEIVED HEAVY RAINFALL FRIDAY
EVENING.
