CLOUDS ARE ISOLATED OVER MOST AREAS FROM NIIHAU TO MAUI BUT THERE ARE SMALL PATCHES OF BROKEN LOW CLOUDS HERE AND THERE. RADARS SHOW SCATTERED MODERATE SHOWERS FORMING ALONG THE KOOLAU MOUNTAINS OF OAHU BUT NO OTHER PRECIPITATION FROM NIIHAU TO MAUI. THERE ARE STILL BROKEN LOW CLOUDS OVER MOST LOWLAND AREAS OF THE BIG ISLAND OF HAWAII WITH CLEAR SKIES OVER THE UPPER SLOPES OF MAUNA KEA AND MAUNA LOA AND ONLY ISOLATED LOW CLOUDS NEAR CAPE KUMUKAHI AND SOUTH CAPE AND ALONG THE COAST OF LEEWARD KOHALA. THERE ARE AREAS OF BROKEN LOW CLOUDS OVER WATER NORTH OF KAUAI... NORTHWEST THROUGH NORTHEAST OF OAHU...SOUTHWEST OF THE ISLANDS OF MAUI COUNTY AND NORTH OF THE WINDWARD KOHALA DISTRICT AND WEST OF THE SOUTH KONA DISTRICT OF THE BIG ISLAND. CLOUDS MOTIONS NEAR THE ISLANDS ARE QUITE VARIABLE. LOW CLOUDS EAST OF THE BIG ISLAND ARE MOVING FROM THE EAST AROUND 10 MPH. IT APPEARS THAT THE FLOW DIVERGES AROUND THE ISLANDS WITH THE FLOW FROM THE EAST SOUTHEAST OFF THE WINDWARD SIDES OF THE ISLANDS AND FROM THE EAST NORTHEAST IN THE AREA SOUTHEAST OF THE BIG ISLAND. SOME REMNANTS OF AN OLD FRONTAL BAND REMAIN NORTH OF THE MAIN HAWAIIAN ISLANDS. THESE AREAS OF LOW CLOUDS HAVE STRETCHED OUT FROM WEST SOUTHWEST TO EAST NORTHEAST AHEAD OF A NEWER FRONTAL BAND 590 MILES NORTH NORTHWEST OF KAUAI. ONE FRAGMENT OF THE OLD FRONT RUNS FROM 26N145W TO 30N144W AND ANOTHER RUNS FROM 27N158W TO 30N150W. THESE FRAGMENTS ARE 100 TO 150 MILE WIDE BANDS OF SHOWERY BROKEN TO OVERCAST LOW CLOUDS. WATER VAPOR IMAGERY SHOWS A TROUGH ALOFT FROM 25N140W...OVER THE BIG ISLAND TO A LOW ALOFT NEAR 13N179E. THE PART OF THE TROUGH EAST OF 150W HAS BEEN MOVING SOUTHEAST SLOWLY WHILE THE REST OF THE TROUGH HAS BEEN NEARLY STATIONARY. A JET STREAM ASSOCIATED WITH THE TROUGH RUNS FROM 16N180W TO 17N175W TO 60 MILES SOUTH OF THE BIG ISLAND TO 23N140W. THERE ARE BROKEN TO OVERCAST CIRRUS CLOUDS SOUTHEAST OF THE JET. THERE IS ALSO AN AREA OF SCATTERED TO BROKEN CIRRUS NORTH OF 25N EAST OF 170W. $$ DONALDSON +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
