AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
222 AM CDT TUE MAR 18 2008

.DISCUSSION...
THE SLOW MOVEMENT OF THE UPPER LOW WILL ALLOW AMPLE SYNOPTIC LIFT
IN THE SATURATED AIRMASS THROUGH TONIGHT. SHOWERS AND
THUNDERSTORMS WILL BE COMMON OVER THE SOUTHEAST HALF OF OKLAHOMA
TODAY UNDER THE INFLUENCE OF SMALL WAVES AHEAD OF THE MAIN UPPER
LOW WHICH IS EXPECTED TO MOVE FROM SOUTHERN CHIHUAHUA INTO CENTRAL
TEXAS DURING THE DAY TODAY. TONIGHT AS THE UPPER LOW MOVES ACROSS
NORTHEAST TEXAS INTO WESTERN ARKANSAS, SOUTHEAST OKLAHOMA WILL
AGAIN BE IN THE SWEET SPOT FOR MORE RAIN. THE FLASH FLOOD WATCH
CONTINUES THROUGH THE DAY, BUT HAS BEEN EXTENDED INTO TONIGHT FOR
SOUTHEAST OKLAHOMA.

A WEAK WAVE ON FRIDAY SHOULD ALLOW FOR A DRY COLD FRONT. NEXT BOTH
THE GFS AND ECMWF BRING A SHORTWAVE TROUGH FROM THE NORTHERN HIGH
PLAINS SATURDAY NIGHT/SUNDAY. A CHANCE FOR RAIN EXISTS THE SECOND
HALF OF THE WEEKEND.
