AN APPROACHING COLD FRONT MAY LEAD TO A MODEST UPTICK IN SHOWER
ACTIVITY SATURDAY AND INTO EARLY SUNDAY, ESPECIALLY OVER THE
WINDWARD SLOPES OF THE BIG ISLAND, WHERE AMOUNTS COULD LOCALLY
EXCEED 1". DRIER AIR WILL PUSH IN FROM THE NORTH AS THE HIGH
PRESSURE BUILDS OVER THE REGION. EAST TO NORTHEASTERLY TRADE WINDS
WILL ALLOW FOR A FEW SHOWERS OVER WINDWARD FACING LOCATIONS, BUT
LEEWARD LOCATIONS SHOULD REMAIN MOSTLY DRY UNDER THIS REGIME. THE
TRADE INVERSION SHOULD KEEP ANY SHOWER ACTIVITY PRETTY SHALLOW AND
LIGHT, AND THUS SIGNIFICANT RAINFALL IS NOT ANTICIPATED.
