THE BAND HAS BEEN MOVING TOWARD THE SOUTHEAST NEAR 10 MPH OVER THE PAST 6 HOURS... WITH THE LEADING EDGE OF THIS BAND ABOUT 400 MILES NORTHWEST OF KAUAI. BETWEEN THE ISLANDS AND THIS FRONTAL BOUNDARY...INFRARED IMAGERY HIGHLIGHTS AN AREA OF BROKEN HIGH CLOUDS WITH A SIMILAR ORIENTATION AS THE FRONTAL CLOUD BAND. NEAR THE ISLANDS...RANDOMLY DISTRIBUTED PATCHES OF SHOWERY LOW CLOUDS ARE SEEN MOVING TOWARD THE WEST WITHIN A DIMINISHED TRADE WIND FLOW. MORE SPECIFICALLY...IMAGERY FOCUSED ON THE ISLANDS REVEALS BROKEN TO OVERCAST CUMULUS /CU/ AND STRATOCUMULUS /SC/ OVER KAUAI OAHU AND MOLOKAI AND ADJACENT WATERS. THESE CLOUDS HAVE INCREASED IN COVERAGE IN THE PAST COUPLE OF HOURS...APPARENTLY IN RESPONSE TO A SOUTHWARD MOVING GRAVITY WAVE. MAUI AND THE BIG ISLAND HAVE FEWER LOW CLOUDS...WHERE SCATTERED SC AND CU PREVAIL OVER THE ADJACENT WATERS. THE LOWER SLOPES OF THE BIG ISLAND...HOWEVER...REMAIN BLANKETED IN BROKEN TO OVERCAST SC AND CU...WHILE SIMILAR LOW CLOUD CONDITIONS ARE OBSERVED OVER THE LOWER SLOPES OF HALEAKALA. LOW CLOUD MOTION NEAR THE ISLANDS IS TOWARD THE WEST AT SPEEDS NEAR 10 MPH. WHILE WATER VAPOR IMAGERY REVEALS A PAIR OF LOWS ALOFT IN THE CENTRAL NORTH PACIFIC...BOTH OF WHICH ARE CUT OFF FROM THE MAIN WESTERLIES LOCATED FARTHER TO THE NORTH. ONE LOW IS NEARLY STATIONARY ABOUT 1050 MILES EAST OF THE ISLANDS...CENTERED NEAR 21N 141W. ANOTHER COMPACT LOW IS CENTERED ABOUT 950 MILES WEST-SOUTHWEST OF KAUAI...NEAR 20N 174W...AND IS MOVING TOWARD THE SOUTH-SOUTHWEST NEAR 10 MPH. A LARGE LOW ALOFT IS CENTERED FAR NORTH OF THE ISLANDS NEAR ALASKA/S ALEUTIAN ISLANDS...AND A BROAD TROUGH EXTENDS SOUTHWARD FROM THE LOW TO A LOCATION ABOUT 425 MILES NORTHWEST OF KAUAI. THE HIGH CLOUDS TO THE NORTH OF THE ISLANDS ARE DEVELOPING IN RESPONSE TO DIFFLUENCE BETWEEN THE TROUGH ALOFT TO THE NORTH AND THE CUT OFF LOW TO THE WEST OF THE ISLANDS. $$ BIRCHARD +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
