AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
818 PM CDT FRI MAY 9 2003

...MESOSCALE CONVECTIVE DISCUSSION...

CAP CONTINUES TO HOLD STRONG IN THE WARM SECTOR OVER OUR CWA.
MOISTURE CONVERGENCE HAS BEEN STRONG ENOUGH FOR CONVECTION TO BREAK
THROUGH THE CAP ALONG THE BOUNDARY THE STRETCHES ROUGHLY FROM NE
INTO WC MO AND THE SSW FROM THERE INTO CENTRAL OKLAHOMA. SIX MINUTE
PROFILER DATA FROM NDSK1 SHOWS THE LOW LEVEL JET BEGINNING TO
INTENSIFY WHICH SHOULD ENHANCE CONVERGENCE OVER THE ALONG THE
BOUNDARY.

CONVECTION OVER NORTH CENTRAL OK SEEMS TO BE TRYING TO ORGANIZE
SOME. IF CONVECTION CAN CONTINUE TO ORGANIZE AND DEVELOP A COLD POOL
THAT MAY BE ENOUGH TO OVERCOME THE STRONG CAPPING INVERSION OVER OUR
AREA BUT LIKELY WOULDNT ARRIVE UNTIL AFTER 4Z.

THREAT OF ANY SEVERE CONVECTION OVER THE MAJORITY OF OUR AREA SEEMS
TO BE QUITE LOW THROUGH 10 PM. ADDITIONAL CONVECTION SEEMS TO BE
DEVELOPING ALONG A NORTHWARD MOVING BOUNDARY IN NE OK...SHOULD THAT
MAINTAIN ITSELF THEN THE OUR WESTERN COUNTIES MAY SEE SOME
CONVECTION WORK ITS WAY INTO THE AREA BEFORE 10 PM.

  THE AIRMASS OVER THE OUTLOOK AREA REMAINS VERY UNSTABLE...HOWEVER

  WILL BE FROM LARGE HAIL AND POSSIBLY SOME DAMAGING WINDS.

  THUNDERSTORMS WILL LIKELY CONTINUE INTO THE OVERNIGHT HOURS WITH
  LARGE HAIL AND LOCALLY HEAVY RAINFALL BECOMING THE PRIMARY THREATS
  AFTER MIDNIGHT. THE GROUND IS ALREADY SATURATED OVER CENTRAL
  MISSOURI SO FLASH FLOODING IS POSSIBLE IF THUNDERSTORMS BEGIN TO
  TRAIN AND PRODUCE HEAVY RAINFALL.

  MORNING...BUT A BRIEF BREAK IS EXPECTED BY LATE MORNING AND EARLY
  AFTERNOON. THEREAFTER...THE COLD FRONT WILL FINALLY PUSH THROUGH
