MODERATE INTO TUE. ENSEMBLES SHOW THAT AN UPPER LOW MAY DRIFT WWD
TOWARDS THE ISLANDS UNDERNEATH A RIDGE ALOFT SAT-MON. IT MAY GET
CLOSE ENOUGH TO THE ISLANDS TO CAUSE SOME DESTABILIZATION LATE MON
INTO WED  BEFORE IT IS PULLED N BY THE NEXT TROF IN THE POLAR
WESTERLIES. THE NEXT AMPLIFYING MID LATITUDE 500MB TROF ALONG 165W
MAY CAUSE PRES TO FALL N-NW OF THE ISLANDS AGAIN THE LATTER

AIR IN PLACE AND NO TROPICAL INFLUENCE...PCPN WILL BE ON THE LIGHT
