A LARGE AREA OF HIGH PRESSURE OVER THE SERN STATES WILL MAINTAIN
OFFSHORE FLOW OVER THE GULF COASTAL AREA INTO PART OF SATURDAY.
MODELS ARE IN REASONABLE AGREEMENT EJECTING THE UPPER LOW NOW MOVING
SLOWLY SWD THROUGH CA INTO THE SRN PLAINS SATURDAY NIGHT....WITH
ATTENDANT LEE CYCLOGENESIS AND DEVELOPMENT OF A SLY LOW LEVEL JET
OVER THE SRN PLAINS AND LOWER MS VALLEY.

OFFSHORE TRAJECTORIES WILL MAINTAIN AN INFLUX OF CP AIR OVER THE NRN
GULF MUCH OF SATURDAY. RICHER GULF MOISTURE WITH SURFACE DEWPOINTS
AROUND 70 SHOULD REMAIN OFFSHORE S OF A WARM FRONT. HOWEVER...THE
STRENGTHENING SSWLY LOW LEVEL JET WILL RESULT IN AN INCREASE IN LOW
LEVEL MOISTURE AS MODIFIED CP AIR ADVECTS INLAND OVERNIGHT ABOVE THE
RELATIVELY COOL AND STABLE BOUNDARY LAYER. THE RESULTING THETA-E
ADVECTION AND ISENTROPIC LIFT WILL LIKELY RESULT IN THE DEVELOPMENT
OF VERY MARGINAL INSTABILITY AND ELEVATED CONVECTION FROM ERN PARTS
THE SRN PLAINS INTO THE LOWER MS VALLEY. ISOLATED LIGHTNING MAY
ACCOMPANY SOME OF THE ACTIVITY...ESPECIALLY NEAR THE COAST WHERE
POTENTIAL FOR SLIGHTLY GREATER INSTABILITY WILL EXIST.
