.DISCUSSION...
THE PRESENT ROUND OF RAIN MOVING SLOWLY ACROSS SOUTH CENTRAL
OKLAHOMA IS EXPECTED TO GIVE AROUND AN INCH OF ADDITIONAL RAIN TO
THESE AREAS BEFORE LATE EVENING TODAY. A MORE SIGNIFICANT WAVE,
ASSOCIATED WITH THE EVENTUAL PASSAGE OF THE STRONG SYNOPTIC-SCALE
UPPER LEVEL WAVE, WILL BEGIN TO BRING RAIN INTO WESTERN OKLAHOMA
EARLY SATURDAY AND EXPAND AND MOVE SLOWLY WEST TO EAST OVER NEARLY
ALL OF OKLAHOMA AND ADJACENT PARTS OF TEXAS THROUGH THE WEEKEND.
A FLASH FLOOD WATCH REMAINS IN EFFECTIVE UNTIL MONDAY. A LARGE
AREA OF 4 TO 5 INCH RAINFALL IS EXPECTED IN SOUTH CENTRAL AND
CENTRAL OKLAHOMA. THE MAJORITY OF THIS IS EXPECTED TO FALL
SATURDAY NIGHT AND SUNDAY WHEN RIVERS ALREADY NEAR OR IN FLOOD
WILL RISE EVEN MORE. HOWEVER, BEFORE THEN, FAIRLY STRONG WIND
SHEAR WILL HELP TO SUSTAIN THUNDERSTORMS SATURDAY, BUT LIMITED
INSTABILITY WILL PROBABLY KEEP SEVERE THUNDERSTORM COVERAGE LOW.
MONDAY WILL BE A TRANSITION DAY TO LESS RAIN BEFORE UNTIL ANOTHER
MORE PROGRESSIVE UPPER WAVE MOVES OVER TUESDAY. THIS WILL BRING A
GOOD CHANCE FOR HEAVY RAIN SINCE THE MOIST AIRMASS WILL REMAIN IN
PLACE. A THIRD GOOD CHANCE FOR MORE RAIN AND STRONG THUNDERSTORMS
LIKELY WILL ARRIVE FRIDAY OR IN THE WEEKEND.
