AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
400 PM HST WED MAR 4 2009

.SYNOPSIS...
HIGH PRESSURE NORTH OF THE STATE WILL KEEP MODERATE TRADE WINDS
BLOWING FOR THE NEXT COUPLE OF DAYS. THE HIGH IS EXPECTED TO WEAKEN
THROUGH THE LATER PART OF THE WEEK WITH A SUBSEQUENT DECREASE IN
TRADE WIND SPEEDS. THE ATMOSPHERE WILL BECOME MORE UNSTABLE INTO THE
WEEKEND LEADING TO INCREASED SHOWERS OVER WINDWARD AND MAUKA AREAS.
LEEWARD AREAS MAY ALSO SEE A FEW SHOWERS OVER THE WEEKEND.

&&

.DISCUSSION...
DOPPLER RADAR IS SHOWING SCATTERED SHOWERS MOVING WESTWARD IN
MODERATE TO FRESH TRADE WIND FLOW. THIS IS PROVIDING SHOWERS FOR
MOST WINDWARD AND MAUKA AREAS WITH A FEW LIGHT SHOWERS MOVING OVER
SOME LEEWARD AREAS AT TIMES.

A UPPER LEVEL TROUGH TO THE WEST OF THE MAIN HAWAIIAN ISLANDS
CONTINUES TO SEND LAYERED MID AND HIGH LEVEL CLOUDS OVER THE ISLANDS
FROM THE WEST AND SOUTHWEST. THESE HIGH CLOUDS SHOULD REMAIN WITH US
THROUGH THURSDAY WITH A GRADUAL EASTWARD SHIFT EXPECTED BEGINNING
FRIDAY. BY SATURDAY MOST OF THE HIGH CLOUDS ARE EXPECTED TO BE EAST
OF THE STATE.

MODELS ARE IN GOOD AGREEMENT WITH THE UPCOMING WEATHER SCENARIO. AT
THE SURFACE STRONG HIGH PRESSURE NORTH OF THE STATE CONTINUES TO
WEAKEN AND WILL MOVE EASTWARD WITH TIME. THIS WILL CAUSE A GRADUAL
DROP OFF IN TRADE WINDS SPEEDS TO NEAR NORMAL LEVELS. ITS ASSOCIATED
SURFACE RIDGE IS EXPECTED TO REMAIN SUFFICIENTLY NORTH OF US KEEPING
US IN TRADE WIND FLOW. IN THE UPPER LEVELS OF THE ATMOSPHERE AN EAST
NORTHEAST THROUGH WEST SOUTHWEST ORIENTED TROUGH IS EXPECTED TO FILL
IN OVER THE STATE. THIS WILL HELP DESTABILIZE THE ATMOSPHERE
ALLOWING FOR THE POTENTIAL OF INCREASED SHOWER ACTIVITY BUT STILL
MOST LIKELY OVER WINDWARD AND MAUKA AREAS. SOME LOCALLY HEAVY
SHOWERS ARE POSSIBLE OVER THE WEEKEND ESPECIALLY OVER THE KONA
SLOPES.
