300 AM CDT MON AUG 18 1997

THE FRONT WILL MOVE NORTH FROM NORTH TX TODAY ACROSS THE FORECAST
AREA.  BY LATE THIS AFTERNOON, IT WILL LIKELY BE SOMEWHERE NEAR THE
OK-KS BORDER SETTING THE STAGE FOR SOME HEAVY RAIN TONIGHT.  THE NEXT
MID-LEVEL WAVE, OVER NORTHERN AZ THIS MORNING, WILL APPROACH WESTERN
OK TONIGHT.  COINCIDENT WITH THIS WILL BE AN UPPER LEVEL JET STREAK
WHICH WILL PUT NORTHERN OK IN THE RIGHT REAR QUADRANT.  AS SOUTH
WINDS CAUSE CONVERGENCE ALONG THE SURFACE BOUNDARY AND THESE UPPER
FEATURES COME INTO PLAY, A LARGE COMPLEX WILL LIKELY DEVELOP ACROSS
SOUTHERN KS/NORTHERN OK TONIGHT.  WITH A VERY RICH MOISTURE SUPPLY IN
PLACE, THE DAY SHIFT WILL HAVE TO FURTHER EVALUATE THE FLASH FLOOD
THREAT.

IN THE MEAN TIME, STORMS WILL PROBABLY FORM AGAIN THIS AFTERNOON
ACROSS SOUTHWEST OK WITH TEMPERATURES REACHING INTO THE MIDDLE AND
UPPER 90S AND THE APPROACH OF THE MID-LEVEL WAVE.

TUESDAY, THE FRONT WILL REMAIN NORTH OF THE STATE WITH SOME AFTERNOON
STORMS DEVELOPING ALONG BOUNDARIES PRODUCED BY TONIGHT'S COMPLEX.
