WATER VAPOR IMAGERY REVEALED A PRONOUNCE SWIRL NEAR 27N88W QUICKLY MOVING NORTH AND ANOTHER CYCLONIC ROTATION NEAR 26N92W. IN ADDITION...A SUB-TROPICAL JET OF 30 TO 40 KNOTS FROM OLD MEXICO OVER BAY OF CAMPECHE TO YUCATAN WAS NOTED. AVN INITIALIZED THE CYCLONIC CIRCULATION OVER THE WEST GULF BETTER THAN THE OTHERS. IN ADDITION...THE AVN IS THE ONLY ONE THAT HOLDS ON TO THE VORT MAX AND TAKES IT OVER THE MOUTH OF MISSISSIPPI RIVER BY 18Z TODAY. THE OTHERS IGNORES THIS FEATURE...A FEATURE WHICH MAY INITIATE CONVECTION EARLY TODAY. WILL BE MORE INCLINE TO AGREE WITH AVN POPS FOR TODAY AND SATURDAY. CYCLONIC CIRCULATION REMAINS OVER THE WEST GULF AND SOMEWHAT TRACKS NORTHEAST TOWARD THE LOUISIANA COAST BY 12Z SATURDAY...PLACING SOUTHEAST LOUISIANA AND SOUTH MISSISSIPPI IN THE NORTHEAST QUADRANT AND UNDER PRETTY GOOD UPPER LEVEL DIVERGENCE. FORECAST SOUNDINGS ON ALL SHORT RANGE MODELS KEEPS PRECIPITABLE WATER VALUE AROUND 2 INCHES AND GREATER THROUGH SATURDAY ALONG WITH WINDS LESS THAN 25 KTS THROUGH THE COLUMN...EXPECTING HEAVY RAINFALL.

BELIEVE THAT STRETCH VORTICITY POTENTIAL WITH APPROACH OF VIGOROUS UPPER LEVEL LOW OUT OF GULF WILL SPAWN SEVERAL WATERSPOUTS OVER THE COASTAL WATERS AND INLAND WATERWAYS THIS MORNING. WILL BE ADDRESSING WITH NOWCASTS LATER TONIGHT ALONG WITH POTENTIAL FOR LOCALLY HEAVY RAINFALL IN LINE WITH CALCULATOR AMOUNTS OF 1.5 TO 3 INCHES EXPECTED WITH COASTAL CONVERGENCE SHOWERS. LOOKING NORTH...VIGOROUS SHORT WAVE IN THE NORTHERN STREAM WILL BROADEN TROUGH OUT WEST. HOWEVER...WESTERLIES DO NOT COME THAT FAR SOUTH ENOUGH TO DRIVE MOISTURE EAST IN THE MID LAYER OVER THE FORECAST AREA. IN FACT...ANTI-CYCLONIC CIRCULATION RE-ESTABLISHES OVER SOUTHEAST CONUS AND NORTHERN OLD MEXICO SUNDAY...VERY WEAK FLOW ALOFT AND MOISTURE IN PLACE OVER THE FORECAST AREA.
