SYNOPSIS
BREEZY TRADES WILL GRADUALLY WEAKEN TO MODERATE SPEEDS WEDNESDAY
THROUGH THE REST OF THE WEEK, BECOMING RELATIVELY LIGHT THIS
WEEKEND. ISOLATED TO SCATTERED SHOWERS WILL CONTINUE TO FOCUS OVER
WINDWARD AND MAUKA AREAS THROUGH WEDNESDAY. THURSDAY, LIGHTER
WINDS WILL SUPPORT SEA BREEZES EACH AFTERNOON, INCREASING CHANCES
OF CLOUDS AND SHOWERS OVER MAUKA AND INTERIOR AREAS WITH LAND
BREEZES CLEARING THESE CLOUDS AND DECREASING CHANCES OF SHOWERS
OVERNIGHT AND EARLY MORNING.
DISCUSSION
A HIGH NORTHEAST OF STATE WILL MAINTAIN BREEZY TRADES THROUGH
WEDNESDAY. A BATCH OF LOW LEVEL CLOUDS AND SHOWERS WILL CONTINUE
TO GENERATE ISOLATED TO SCATTERED SHOWERS MAINLY ALONG WINDWARD
AND MAUKA AREAS. CLOUDS AND MODERATE SHOWERS HAVE DEVELOPED ALONG
THE UPSLOPE OF THE KONA COAST OF THE BIG ISLAND THIS AFTERNOON AS
SEABREEZES HAVE KICKED IN. EXPECT CLOUDS AND SHOWERS TO CLEAR
ALONG SHORTLY AFTER SUNSET AS LAND BREEZES DEVELOP ALONG THE KONA
SLOPES OF THE BIG ISLAND.
NEAR TERM MODEL ANALYSIS SHOWS THE HIGH NORTHEAST OF THE STATE
GRADUALLY SHIFTING FURTHER NORTHEAST TONIGHT AND WEDNESDAY ALLOWING
WINDS TO EASE A NOTCH COMPARED TO TODAY. CONTINUE TO EXPECT CLOUDS
AND SHOWERS TO FOCUS MAINLY ALONG THE WINDWARD AND MAUKA AREAS
TONIGHT AND EARLY WEDNESDAY MORNING WITH DRYING TREND STARTING
WEDNESDAY AFTERNOON. THIS WILL BE TO A COMBINATION OF WEAK LIFT
FROM EASING TRADEWINDS AND DRIER AIR FILTERING IN FROM THE EAST.
THE HIGH WILL BEGIN TO WEAKEN THURSDAY THROUGH THE WEEKEND AS A WEAK
COLD FRONT APPROACHES THE STATE FROM THE NORTHWEST. BREEZY TRADEWINDS
WILL WEAKEN TO LIGHT TO GENTLE SPEEDS FRIDAY AND HOLD THROUGH THE
WEEKEND IN RESPONSE TO THE LACK OF A PRESSURE GRADIENT ACROSS THE
STATE. THE LIGHTER WINDS WILL ALLOW FOR SEABREEZES TO DEVELOP
EACH AFTERNOON BEGINNING THURSDAY THAT COULD SLIGHTLY INCREASE
CHANCES CLOUDS AND SHOWERS DEVELOPING UPSLOPE OF MOUNTAIN TERRAIN
AND OVER INTERIOR AREAS, HOWEVER AVAILABLE MOISTURE WILL BE
LIMITED.
LATE THIS WEEKEND THE SURFACE HIGH FAR NORTHEAST OF THE STATE
WILL BUILD BACK AS THE FRONT DISSIPATES TO THE NORTH. BREEZY NORTHEAST
TRADES WILL GRADUALLY BUILD BACK SUNDAY INTO EARLY NEXT WEEK. A
MORE TYPICAL BREEZY TRADEWIND PATTERN WILL RETURN NEXT WEEK AS
CLOUDS AND SHOWERS BECOME MORE FOCUSED ALONG WINDWARD AND MAUKA
AREAS.
