MODELS IN GENERALLY GOOD AGREEMENT BUT BELIEVE THAT NGM IS VERIFYING
WELL AND WILL THEREFORE FOLLOW IT CLOSELY AT THIS TIME. WITH THIS IN
MIND...BASED ON SATELLITE I CAN SEE TWO AREAS OF MOISTURE
CONVERGENCE...ONE MOVING ACROSS US AT THIS TIME AND ANOTHER SOUTH OF
U.S.V.I. LOW TO THE NORTHWEST WITH TROUGH AXIS EXTENDING TO
HISPANOLA WILL BEGIN TO PULL NORTHWARD. AS THE LINGERING TROUGH
PULLS NORTH OF THE AREA TONIGHT RESULTING IN AN INDUCED LOW LEVEL
TROUGH TO SET UP TEMPORARILY JUST WEST OF LOCAL AREA PULLING THE
MOISTURE CURRENTLY SOUTH OF THE U.S. VIRGIN ISLANDS ACROSS US.

PUERTO RICO AND U.S. VIRGIN ISLANDS TO REMAIN IN THE SOUP THROUGH
NOON ON WEDNESDAY BEFORE WE SEE THE MAJORITY OF THE MOISTURE PULL
NORTH OF AREA. SATELLITE ANALYSIS SHOWS A BREAK BETWEEN MOISTURE
MOVING THROUGH AND ANOTHER SHOT WHICH I WILL WILL MOVE THROUGH
TONIGHT. THIS BEING THE CASE WITH ENOUGH MOISTURE LINGERING ON
WEDNESDAY AFTERNOON DIURNAL PATTERNS WILL BE THE DEFINING
THUNDERSTORMS PRODUCER. ALTHOUGH NO LARGE SCALE LIFT IN
ORDER...CONDENSATION PRESSURE DEFICIT INDICATES THAT ONLY A SMALL
AMOUNT OF LIFT WILL BE NEEDED TO GET CONDENSATION. THIS BEING THE
CASE WILL INCREASE POPS AND CHANCE OF THUNDERSTORMS FOR TONIGHT.
