10 AM HST THU FEB 8 2001

SUMMARY...HIGH CLOUDS COMING UP FROM THE SOUTH WILL BLANKET THE
ISLANDS. THE SOUTHERN EXTENSION OF A LOW PRESSURE SYSTEM NORTH OF
HAWAII WILL MOVE WEST FROM THE BIG ISLAND TO KAUAI THE NEXT COUPLE
OF DAYS. A CHANCE OF HEAVY SHOWERS AND THUNDERSTORMS WILL ACCOMPANY
THE EXTENSION.

DISCUSSION...HEAVY SHOWERS AND THUNDERSTORMS FORMED OVERNIGHT OVER
THE COASTAL WATERS EAST AND SOUTHEAST OF THE BIG ISLAND. THE
MOISTURE FOR THE DEEP CONVECTION WAS PROVIDED BY CONVERGENT LOW
LEVEL FLOW INTO A LOW NORTH OF THE ISLANDS. THE INSTABILITY WAS
PROBABLY PROVIDED BY AN UPPER TROUGH TO THE WEST AND PERHAPS THE LOW
ITSELF. THE CONVECTION WILL CONTINUE TO MOVE OVERLAND THE SOUTHEAST
PART OF THE BIG ISLAND.

THE LOW IS PRESENTLY CENTERED ABOUT 500 MILES NORTH OF KAUAI AND
MOVING TO THE NORTHWEST. THE MOISTURE ON THE BIG ISLAND WILL MOVE
WEST UP THE ISLAND CHAIN AS THE LOW MOVES AWAY. THERE IS A CHANCE OF
HEAVY SHOWERS AND THUNDERSTORMS IN THE FORECAST BECAUSE THE MOIST
AND UNSTABLE ATMOSPHERE AND BECAUSE AFTERNOON HEATING MAY AIDE AND
ABE)T THE CONVECTIVE PROCESS. CRAIG
