THE MARITIMES AND SHORTWAVE RIDGING TO THE WEST. AS THE LARGE UPPER
LOW PULLS AWAY LATER TODAY INTO SUNDAY, A WEAK SHORTWAVE AND
ATTENDANT LOW PRESSURE WITH AN INVERTED TROUGH APPROACH THE AREA.

PRECIPITATION SHOULD START BY LATE MORNING INTO EARLY AFTERNOON FROM
NORTHWEST TO SOUTHEAST ALONG THE INVERTED TROUGH. GUIDANCE CONTINUES
