EVENT...POSSIBLE HEAVY RAIN THREAT AS AN UPPER-LEVEL TROUGH APPROACHES
FROM THE WEST
.
SATELLITE ANALYSIS AND TRENDS...WATER VAPOR IMAGERY DEPICTS TWO
UPPER-LEVEL TROUGHS IN THE VICINITY OF THE ISLAND CHAIN. THE FIRST IS TO
THE EAST OF THE BIG ISLAND AND SLOWLY MOVING NORTHWARD WHILE THE SECOND
IS TO THE WEST OF KAUAI AND MOVING EASTWARD TOWARD THE STATE. THE BLENDED
TPW PRODUCT CONTINUES TO DISPLAY BETTER MOISTURE BEING TRANSPORTED TO THE
ISLANDS WITH THE LOW-LEVEL FLOW BEING EASTERLY TO SOUTHEASTERLY. LIHUE`S
00Z SOUNDING SHOWS THE INCREASE IN MOISTURE, WHILE SHOWING AN INCREASE
IN INSTABILITY FROM THE 12Z SOUNDING, NOW AROUND 1200 J/KG.
.
SHORT TERM OUTLOOK VALID 0405-1000Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...GIVEN THE GOOD MOISTURE, SHOWERS ARE POSSIBLE
OVERNIGHT ACROSS MAINLY WINDWARD SECTIONS OF THE ISLAND CHAIN. THE
UPPER-LEVEL TROUGH TO THE WEST OF THE STATE SHOULD IMPACT THE STATE
OVERNIGHT. AS IT MOVES EASTWARD TOWARD THE ISLANDS, INCREASED MOISTURE
AND LOCAL EFFECTS COULD HELP TO ENHANCE RAINFALL TOTALS ACROSS KAUAI,
NIIHAU AND POSSIBLY THE ISLAND OF OAHU LATER IN THE OUTLOOK. THE INCREASE
OF INSTABILITY TO COULD LEAD TO SOME POSSIBLE CONVECTION FOR KAUAI,
NIIHAU, AND SURROUNDING WATERS, BUT CONFIDENCE IS LOWER.
