.
SATELLITE ANALYSIS AND TRENDS...LATEST WV IMAGERY INDICATES LARGE SCALE
MID-UL TROF AXIS LOCATED JUST NORTH OF THE HAWAIIAN ISLANDS. BEST FORCING
FROM THIS FEATURE IS ROTATING OVER THE ERN PART OF MAUI AND EXTENDING
OVER THE BIG ISLAND. CIMSS & NOAA/NSSL EXPERIMENTAL WIND PRODUCT SHOWS
75 KT JET STREAK PROPAGATING EWRD TOWARDS THE BIG ISLAND ENHANCING UL
DIVERGENCE OVER ERN HAWAII. 12Z RAOB PW VALUES WERE AT 1.7" WHICH ARE 2
STD DEV ABOVE NORMAL AND BLENDED TPW ANALYSIS CONTAINS PW VALUES GREATER
THAN 2.0" JUST SOUTH OF THE ISLAND. FOR THE MOMENT CONVECTION REMAINS
OFFSHORE MOSTLY TO THE S/SE OF HAWAII.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 1930Z-2230Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...SHOWERS/ISOL TSTORMS ARE LIKELY TO SPREAD ONSHORE
FROM EAST TO WEST AS FORCING FROM UL TROF/JET STREAK COINCIDE OVER THE
ISLANDS WITH ANOMALOUSLY HIGH MOISTURE VALUES. BEST FORCING/HEAVIEST RAINS
ARE EXPECTED TO REMAIN OVER THE BIG ISLAND WITH MORE SHOWERY ACTIVITY
EXTENDING NORTHWESTWARD TOWARDS MAUI AND THE OTHER CENTRAL ISLANDS DUE
TO LOWER MOISTURE VALUES/LESS MID-LVL FORCING. EASTERLY FLOW NEAR THE SFC
SHOULD ENHANCE RAINFALL ALONG WINDWARD FACING SLOPES OF THE BIG ISLAND.
