SATELLITE ANALYSIS AND TRENDS...IR IMAGERY SHOWS TWO LINES OF CNVTN OVER
HAWAII AT THIS TIME..ONE MOSTLY OF THE WATERS BETWEEN THE BIG ISLAND
AND MAUI AND THE OTHER NE OF KAUAI. WV IMAGERY SHOWS THIS CNVTN WRAPPING
NWD INTO WHAT IS LEFT OF THE UPPER LOW..TRACKED TO NEAR 29N/157W. CLOUD
TOP TEMPS OVER THE ERN PART OF THE STATE HAVE SHOWN A GENERAL WARMING
TREND OVER THE PAST FEW HRS WITH THE EXCEPTION OF CELLS NE OF THE BIG
ISLAND. NEWEST CELLS HAVE FORMED OFF THE W COAST OF THE BIG ISLAND BUT
EXPECT THE HEAVIEST RAINS TO REMAIN OFFSHORE. RECENT TRENDS HAVE BEEN FOR
CELLS TO STAY OVER THE WATERS BETWEEN THE TWO ERN ISLANDS BUT BELIEVE
THAT MAUI COULD SEE SOME HEAVIER PRECIP OVER THE NEXT FEW HRS AS CELLS
MOVE MORE NWD IN THE FLOW.
.
OVER KAUAI BOTH VIS AND IR INDICATE THAT CNVTN SHOULD CONTINUE TO
BACKBUILD ALONG A BNDRY STRETCHING DIRECTLY OVER CENTRAL KAUAI AND ACROSS
NIIHAU THEN OFF TO THE SW. CELLS OVER AND JUST NE OF KAUAI HAVE CLOUD
TOPS OF -40 TO -49C. SSMI PASSES FROM AROUND 16Z SHOWED THE TWO SEPARATE
MOISTURE PLUMES FEEDING INTO THE UPPER LOW N OF HAWAII WITH AN AREA OF
DRIER AIR IN BETWEEN OVER THE CENTRAL ISLANDS. PW VALUES OF 1.6-1.7"
WERE SEEN IN BOTH PLUMES WITH SLIGHTLY HIGHER VALUES UP TO 1.85" NE
OF THE BIG ISLAND. SOME OF THE AREAL AVG INSTANTANEOUS RAIN RATES FROM
THE SSMI SENSOR WERE AROUND .25"/HR WITH THOSE NE OF THE BIG ISLAND UP
TO .35"/HR. THESE RATES WOULD BE OBVIOUSLY BE INCREASED BY THE LOCAL
TERRAIN OF THE ISLANDS. SEE WEB ADDRESS IN 10-15 MIN FOR GRAPHIC.
