HAVE ISOLATED TO SCATTERED CONVECTION THIS MORNING STREAMING IN FROM THE GULF...AND HELPED BY WEAK SURFACE FRONT STALLED NEAR THE COAST. THIS BOUNDARY SHOULD WEAKEN AND LIFT NORTH TODAY. COMBINE THIS BOUNDARY...THE ABUNDANT MOISTURE STILL IN PLACE AND A UPPER LEVEL DISTURBANCE AND WE SHOULD GET SCATTERED CONVECTION TO DEVELOP ONCE AGAIN. NOT REALLY EXPECTING ANYTHING ORGANIZED...BUT CERTAINLY HIGH RAINFALL RATES WILL BE POSSIBLE WITH SOME OF THESE SHOWERS/STORMS AND COULD LEAD TO ISOLATED FLASH FLOODING.

THE COMBINATION OF COPIOUS MSTR/UPPER FORCING AND A MEANDERING SFC BOUNDARY/TROUGH (GFS DETERMINISTIC AND TO A LESSER EXTENT THE ECMWF) WL CONTRIBUTE TO SCT/NUMEROUS CONVECTION SATURDAY NIGHT THROUGH MONDAY NIGHT. STG 0-6KM VERTICAL SHEAR MAY CONTRIBUTE TO STG/SEVERE CONVECTION SUNDAY...CONSISTENT WITH SLGT RISK FOR SVR FROM SPC. FLASH FLOODING IS ANOTHER THREAT OWING TO ALREADY WET/NEAR SATURATED SOIL CONDITIONS/LOW FLASH FLOOD THRESHOLDS. A TRANSITON TO DRIER CONDITIONS ANTICIPATED FOR TUESDAY.
