AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 407 AM CST MON NOV 17 2003 SCATTERED THUNDERSTORMS DEVELOPED IN THE WEST THIS MORNING... AND ALTHOUGH THEY ARE CONTINUING TO MOVE TO THE NORTHEAST THERE HAS BEEN LITTLE SIGN OF REDEVELOPMENT SO FAR. THE MODELS ARE IN DECENT AGREEMENT WITH THE BEST LIFT DEVELOPING ACROSS THE SOUTHEAST HALF OF THE AREA THROUGH THE DAY. MOISTURE IS SURGING NORTHWARD AND LOW CLOUDS HAVE MOVED INTO ALMOST THE ENTIRE AREA. SURFACE DEWPOINTS IN THE MID 60S ARE HAVE MOVED INTO SOUTH CENTRAL OKLAHOMA. MAY SEE SOME RELATIVELY HEAVY RAIN ESPECIALLY IN THE SOUTHEAST TODAY AND WILL MENTION HEAVY RAIN IN THOSE ZONES. WILL ALSO LIKELY MAKE LAST MINUTE ADJUSTMENTS ON FIRST PERIOD POPS. PRECIP MAY LINGER A LITTLE BIT LONGER INTO THE SECOND PERIOD IN THE EASTERN PART OF THE AREA AND WILL RAISE POPS A TOUCH. BUT PRECIP WILL MOVE OUT AS THE DRYLINE AND COLD FRONT EXIT THE AREA TONIGHT. THE 16/00Z GFS SEEMS TO HAVE BEEN THE ABERRATION AND THE LATEST RUN SHOWS A BIG BOWLING BALL UPPER LOW MOVING INTO THE CENTRAL PLAINS ON SUNDAY. THE RUN TO RUN CONSISTENCY OF THE MEDIUM RANGE MODELS HAS BEEN VERY LOW LATELY. BUT WITH A LITTLE CONSISTENCY IN THE BROAD PATTERN AMONG THE LATEST MODELS WILL TREND SUNDAY AND SUNDAY NIGHT TEMPERATURES LOWER. BUT CONFIDENCE IS NOT HIGH YET.
