..WET PATTERN AGAIN ON TAP THIS WEEK
ISLAND TRADES HAVE INCREASED AS SURFACE HIGH PRESSURE CELLS
BRIDGE TO THE NORTH OF THE STATE. THIS FAVORS A GENERALLY WET
TRADE PATTERN GIVEN LINGERING MOISTURE FOR EARLY THIS WEEK, WITH
MORE FOCUS ON WINDWARD TERRAIN. GUIDANCE GENERALLY AGREES THAT
UPPER TROUGH/CLOSED LOW AND SURFACE SYSTEM GENESIS REMAINS SET TO
DIG AND SETTLE JUST TO THE WEST OF THE STATE BY MID-LATER WEEK.
WEAKENING AND VEERING LEAD FLOW TO SOUTHEASTERLY TO SOUTHERLY
WINDS OVER THE STATE SHOULD DEEPEN LEAD MOISTURE TO FUEL SHOWERS
AND SOME HEAVIER LOCAL DOWNPOURS. THE UPPER SYSTEM SHOULD SLOWLY
EJECT AND LOSE INFLUENCE INTO THE WEEKEND, BUT A MOISTURE POOLING
TRAILING FRONT AND SHOWERS FOCUS MAY WORK SLOWLY INTO THE STATE.
