...BREEZY TO WINDY CONDITIONS SLOWLY ABATING AND LINGERING
SHOWERS BEFORE WHAT MAY PROVE TO BE ONLY A BRIEF RESPITE...
SCATTERED TO NUMEROUS SHOWERS ARE EXPECTED TO PERSIST INTO THE
LATTER PART OF WEEK...ESPECIALLY ACROSS WINDWARD FACING PORTIONS
OF THE ISLANDS...UNTIL DRY AIR ADVECTS INTO THE REGION LATER IN
THE WEEK. THE DRY ADVECTION WILL BE IN RESPONSE TO STRENGTHENING
HIGH PRESSURE AT THE SURFACE. BREEZY TO WINDY CONDITIONS ARE ALSO
LIKELY IN RESPONSE TO THE PRESSURE GRADIENT BETWEEN THE HIGH TO
THE NORTHEAST AND A BROAD TROUGH OF LOW PRESSURE TO THE SOUTH AND
WEST OF THE ISLAND. WINDS SHOULD VEER WITH TIME STARTING ON SUNDAY
OR MONDAY AS THE SURFACE HIGH PRESSURE AREA BUILDS
SOUTHWARD...WHICH STARTS TO DRAW DEEPER MOISTURE NORTHWARD.
OVERALL THE MODEL GUIDANCE IS IN GOOD AGREEMENT WITH THE SYNOPTIC
SCALE FEATURES...HOWEVER THE GFS CONTINUED TO BE MORE INCLINED TO
BE WETTER THAN THE ECMWF INTO THE FIRST HALF OF NEXT WEEK (MORESO
IN THE WESTERN ISLANDS).
